How to avoid scams with HVAC Repairs


Talking about scams and dishonest business isn’t really a fun topic; and the fact that these kinds of things exist at all is pretty disheartening. But the truth of the matter is that it does happen. And you need to know how to spot Birmingham HVAC scammers!

At 3D Air Services there is absolutely nothing we take more seriously than protecting our patrons. When you need Birmingham HVAC services, you need a reliable and effective solution. Part of finding this is knowing exactly what to look for, and what to avoid.


The summer season unfortunately brings a lot of unsavory characters out of the woodwork. Be wary of any of the following situations:

Unsolicited visits. Professionals do not run around town looking for HVAC problems. When you need our help, you know who to call! If a stranger shows up at your door citing some oddball and sudden HVAC “emergency” that requires immediate attention, don’t be fooled. On the off chance that you’re just dealing with a good samaritan, go ahead and schedule a visit from HVAC professionals. But some off-the-street handyman that wants to come into your home should never be trusted.
“Cash up front” services. If your chosen HVAC technician wants full payment up front, you probably want to drop them. This is a common scam, and most of the time, you’ll never see this person (or your money) ever again. And be doubly wary of cash only services. We live in a modern world, and folks that only accept cash for contracted work probably aren’t pros.
Unprofessional behavior. Your HVAC expert doesn’t need to show up in a suit and tie speaking oxford english or anything, sure. But if you call in for service and the person that shows up is rude, uncouth, or given to withholding information, don’t work with them! Scammers aren’t often all that friendly, and if they are, it usually feels decidedly fake.


Most of the time, a professional HVAC contractor is pretty easy to spot. When you’re looking for a trustworthy and dependable service, be sure they have:

Credentials. Licensing and insurance are clear hallmarks of a real, professional business. If you’re planning on getting some Birmingham HVAC service, make sure your chosen service experts are actually experts!
Marks and branding. When a 3D Air service vehicle rolls up, you know it’s us. It’s the same for most proper businesses. Uniforms, verifiable business cards, branded vehicles; all of these things are signs that you’re dealing with a real business and not a fly-by-night scammer.
Good reviews. It’s the technological age, and computers are a common part of most United States homes. Use this to your advantage! Seek out testimonials and reviews from actual customers online (they’re pretty easy to find) to see whether or not previous experiences with the company have been positive.

Air conditioner blowing hot?

Trying to stay cool in an Birmingham home, There’s nothing worse than sitting in your home and realizing that your air conditioner is blowing hot air–especially during the sickeningly hot summer months.

Even though It’s not summer yet, you don’t want to look for answers for why your air conditioner isn’t working when you’re burning up inside your home. It’s best to know the reasons ahead of time so you’ll know how to avoid them or when to call a professional.

So what causes this annoying phenomena? Here are 4 common reasons:

1) Thermostat turned to heat mode

Ok, this might be a huge “duh” but if you’re getting hot air, you might have accidentally flipped your thermostat to “heat” mode. It happens to all of us. If that’s the case, switch it back to “cool” and you’re good to go.

2) Dirty evaporator coil caused by a dirty air filter

Chances are, your thermostat is set to cool, and you’re still getting hot air. Now what?

The cause could be a dirty evaporator coil caused by a dirty air filter. This keeps your air conditioner from properly cooling your home. You can change the filter, but you’ll need a professional to clean the evaporator coil.

3) Outside AC unit not properly maintained

Walk outside and look at your air conditioner’s outside condenser unit. What do you see?

Is there anything blocking the condenser coils air flow? Are they blocked with dirt and debris?

If so, this seriously impacts your air conditioner’s cooling ability.

Cleaning the condenser coils needs to be a regular activity during the summertime.

4) Low on refrigerant/Freon

This is the usual culprit. Your air conditioner needs a proper refrigerant (usually Freon) charge to cool your home.

So a Freon leak can leave you feeling the heat since you’ll have a complete loss of cold air.

You can tell if your air conditioner doesn’t have enough Freon if ice forms on the inside and outside units.

Getting a Freon charge is best left to a professional.

Get AC maintenance done during the spring

Keeping an eye on these problems will not only will this keep your air conditioner from blowing hot air, it will also prevent a costly breakdown. And the last thing you want is a breakdown during summer.

So it only makes sense to get preventative maintenance done during the spring before it gets too hot.

Is my air conditioner over heating?

What Does it Mean When Your Air Conditioner is Overheating?
Overheating” is a term that you might hear applied to many different appliances and electronics, but it can be pretty vague. Does it mean something was sitting out in the sun too long? Working too hard? Left in a sauna? While we can’t speak for every product you own, we can definitely provide you with some information on what overheating means when it’s applied to your air conditioner. Today we’re going to explain what happens when your air conditioner is overheating and what can cause the problem!

What does it mean when your air conditioner is overheating?

When an air conditioner is overheating, it’s putting in much more work than it is capable of handling. This forces the system to consume a huge amount of energy, which causes one or more of its parts to heat up and eventually shut down. The most obvious sign that your air conditioner is overheating is when your system trips the circuit breaker. This happens when the flow of electricity to your air conditioner is too high and your system shuts down as a safety precaution.

There are many different components of your air conditioner that can overheat, including the compressor, fan motors, capacitors and more.

Why do air conditioners overheat?

Clogged air filter. When your air conditioner’s fan pulls in air from your home to be cooled, that air must pass through a filter. If your filter is clogged, the fan will have to work much harder than usual to do its job. You can compare this to the difference between taking a deep breath normally and taking a deep breath through a straw; you have to put in much more effort when your flow of air is restricted through a straw. The extra effort that your fan must exert when your filter is clogged can cause it to overheat.
Dirty fan blades. Another thing that can cause your air handler to overheat is dirt buildup on the fan’s blades. As dirt accumulates on the blades, it weighs them down and makes it much harder for the fan to spin. This can eventually cause the fan to overheat.
Low refrigerant levels. Your air conditioner is designed to operate with a specific amount of refrigerant. If your system has a refrigerant leak, it will not have enough refrigerant available to cool your home properly. This forces your air conditioner to work much harder and longer than usual, which can lead to overheating.
Dirty or frozen coils. If your air conditioner’s cooling coils are either dirty or frozen over, there will be a barrier in between the coils and the air that’s blown over them. This can cause overheating because it will diminish the transfer of heat from your home’s air, which means your system will have to work overtime to keep your home cool.
Old age mixed with hot weather. Old age on its own can cause an air conditioner to overheat because its parts will be inefficient and outdated. Overheating will happen even quicker in hot weather, because the aging system won’t stand a chance against the high outdoor temperatures.
General lack of maintenance. Almost all of the issues above can be prevented by taking good care of your air conditioner throughout its lifetime. If you don’t change your filter monthly or schedule tune-ups annually, the likelihood of your system overheating will increase dramatically.

5 Reasons to Consider a new Thermostat

When to Replace Your Thermostat: 5 Situations When You Should Consider a New Unit
Thermostats are tightly integrated with your heating and cooling system, but that doesn’t mean you have to use the same thermostat throughout the lifetime of your furnace and air conditioner. In fact, there are a number of reasons why you might consider replacing your current thermostat even if you won’t be replacing your heating and cooling system any time soon. Today we’re going to talk about 5 situations when you should consider replacing your thermostat and how it can benefit your home!

5 situations when you should consider replacing your thermostat

You’re replacing your heating and cooling system. Perhaps the most obvious time that you’ll want to replace your thermostat is when you install a new heating and cooling system. It’s rare that you’ll want to keep the same thermostat when you switch to a new system for a couple of reasons. For one, your thermostat is likely old and there are sure to be much better models out there now than there were when your current thermostat was installed. Also, your current thermostat might not be compatible with the design and features of the system that you’re about to install.
You’re adding a zoning system. A zoning system divides your home into separate sections that each have their own thermostat. In addition to installing more thermostats in your home when you add a zoning system, you might need to replace your current thermostat. That’s because not every thermostat is compatible with a zoning system, so you’ll likely need to replace your current unit with a thermostat that can control zoned heating and cooling.
You have a manual thermostat. Do you have to walk up to your thermostat and change it manually every time that you want to adjust your home’s temperature levels? If so, you should consider replacing your manual thermostat with a programmable model. A programmable thermostat allows you to save different settings for different times of the day, and it will adjust itself automatically without you having to lift a finger.
You prefer a touchscreen display. We live in a digital world where most of our gadgets are controlled by touchscreens instead of manual buttons. Touchscreens are not only easier to use, but they also tend to look better on a wall. If you have an outdated dial or button thermostat, consider replacing it with one that has a touchscreen display.
You want to control your thermostat remotely. More and more appliances are being designed with “smart” capabilities that connect them to the Internet, and thermostats are no exception. If you’d like to monitor and adjust your home’s comfort levels remotely, consider replacing your thermostat with a Wi-Fi enabled model.

How Humidity Effects Your Home

imageWhen your air conditioner is running, it’s not just cooling down your home; it is lowering humidity levels as well. That’s because when heat is removed from air moisture is released in the form of condensation. So if something goes wrong with your air conditioner, your home’s humidity levels can get too high and cause all kinds of issues. Today we’re going to talk about the effects of high humidity levels at home and what you can do to ensure your air conditioner can effectively remove moisture from the air!

The effects of high humidity at home Comfort and efficiency issues. When humidity levels are high, homes tend to feel warmer than they actually are. As a result, many people lower their thermostat settings to compensate for the uncomfortable environment. This is a waste of energy because your air conditioner will have to work harder to make your home feel comfortable.
Unhealthy air. Airborne contaminants like bacteria, viruses and dust mites tend to thrive in areas of high humidity. Not only does this increase the likelihood of people in your home getting sick, but it also makes symptoms worse for people who suffer from asthma or allergies.
Excess condensation. High humidity means there is excess moisture in the air. This tends to be most visible on your windows where you can see condensation dripping down the glass. If this happens for a prolonged period of time, it can damage wooden frames and nearby walls.
Damage to furniture. When there is a lot of moisture in the air, wooden furniture can get damp and stained. In severe cases, this can cause permanent damage.
Damage to musical instruments. Humidity can be a huge problem for instruments that are made of wood, such as guitars and violins. The moisture in the air causes the wood to swell, which can cause glue joints to fail, finish to lift, and neck angles to go bad.
Spoiled food. Certain foods can go bad quickly if humidity levels are high. This is most problematic for food that you would normally store in a cabinet or on the counter, such as bread and starchy vegetables.
Keep humidity levels under control by taking care of your air conditioner

The best way to ensure that humidity levels stay under control during summer is to take good care of your air conditioner. If your air conditioner is dirty, experiencing operational issues or having problems with the condensate line, it will not be able to remove moisture as effectively as it should. By scheduling annual tune-ups and regularly changing your air filter, you can greatly help avoid problems like these and keep your home’s humidity at the right levels.

Effects of a dirty air conditioner?

What are the Effects of a Dirty Air Conditioner?
Dirt can be a nuisance anywhere in your home, but one place that it poses some of the biggest problems is mostly hidden from view: inside your air conditioner. Dirt buildup on your air conditioner can cause huge performance and efficiency problems, which is why you should take steps to keep your system clean. Today we’re going to help you do that by talking about the effects of a dirty air conditioner and what you can do to prevent dirt from building up on your system!

How does an air conditioner get dirty?

When your air conditioner is operating, it pulls in air from your rooms in order to be cooled. As this happens, any dirt that has built up in your rooms can get caught up in your system’s airflow. That dirt travels through your return ducts until it encounters your air filter. If you have a good and clean air filter, the dirt should get trapped by the filter and only clean air should move on past it. If your filter is dirty or inefficient, dirt can bypass your filter and build up on your air conditioner’s components.

Dirt can also build up on your air conditioner’s outdoor unit over time simply due to the fact that it operates outside where dirt and debris are constantly blown around.

What are the effects of a dirty air conditioner?

Airflow can get blocked. If your air filter is completely covered in dirt, your system’s airflow will be severely impaired. That’s because your air handler will have to work extremely hard to try to push air past the clogged filter. This will greatly increase your system’s energy consumption and can also damage your air handler.
Your air handler can slow down. When dirt builds up on your air handler’s fan’s blades, the blades will not be able to spin as fast. As a result, your fan might not be able to operate powerfully enough to meet your home’s airflow demands. Your fan will also consume more energy while attempting to make up for the lack of performance.
Your cooling coils can lose effectiveness. Inside your home, your air conditioner blows warm air over evaporator coils and the coils remove heat from that air. Meanwhile outside, your condensing unit blows air over condenser coils, transferring heat from your home to the air outside. If either sets of these coils have a layer of dirt on them, the transfer of heat will be much more difficult. This can impair the ability of your air conditioner to adequately cool your home and often leads to frozen evaporator coils.
Your thermostat can get improper readings. If your air conditioner is cycling a lot of dirt in your home’s air, that dirt can build up on your thermostat. This can cause your thermostat to give false temperature readings, which can make it nearly impossible to keep your home comfortable.
How can you prevent your air conditioner from getting dirty?

Get annual tune-ups for your air conditioner. During a tune-up, we’ll perform a full system cleaning on your air conditioner in order to remove any dirt that might have built up since your last maintenance appointment.
Change your air filter every month. Your air filter is responsible for protecting your air conditioner from dirt buildup. In order to ensure it can do its job properly, change your filter every month.
Regularly clean your home. By controlling dirt at its source, you can limit the amount of it that gets caught up in your home’s airflow. Sweeping, vacuuming and wiping your home’s surfaces will all help remove dirt from your home and limit the amount or dirt that your air conditioner is exposed to.

Common sources of heat gain

Air conditioners don’t technically “produce” cool air. Instead, they remove heat from your home’s air in order to cool it down. So the more heat that your home contains, the harimageder your air conditioner will have to work to keep your home comfortable. “Heat gain” is a term that’s used to describe heat that is added to your home from an indoor or outdoor source. Today we’re going to talk about  of the most common sources of heat gain in your home so that you can help minimize their effects and improve the comfort and efficiency levels in your home!

Common sources of heat gain in Birmingham area homes

Sunlight shining through windows. When the sun is shining on a hot summer day, its rays can beam right through your windows and add a significant amount of heat to your home. There are a few different ways you can help limit this source of heat gain. First, you can close the drapes and blinds on your windows to block out the sun during the day. Second, you can provide shade to your windows by either installing awnings or planting trees near them. Third, you can install more efficient windows that are designed to reduce air leakage and minimize heat gain.
Sunlight beaming down on your roof. In most homes, the attic on the top level is not a conditioned space. As a result, an attic can get extremely hot during the day when the sun beats down on your roof. This heat can infiltrate downwards into your home’s living spaces, resulting in heat gain. You can minimize this source of heat gain by improving insulation levels in your attic so that heat doesn’t make it through the attic floor.
Cooking activities. Most cooking activities involve some sort of heat-producing appliance, whether that be the oven, the stove or a crockpot. While you are cooking with those appliances, heat is constantly being added to your kitchen and warming up the other surrounding rooms. You can limit this source of heat gain by using your microwave as an alternative whenever possible or taking your cooking completely outside onto your grill.
Indoor appliances. Lamps, computers, washing machines, dishwashers and driers are just a few examples of the types of heat-producing appliances that can be found in almost every home. You should use these appliances wisely in order to minimize the amount of heat gain that they can produce. Make sure to turn off lamps, computers and other electronics when they are not in use, and try as best you can to only do laundry or the dishes at night when it’s cooler outside.
Showers. The hot water that we use in the shower produces water vapor that can quickly heat up a bathroom and also seep outside to the surrounding rooms. The easiest ways to limit this source of heat gain are to take shorter showers and make sure to run your bathroom’s ventilation fan while you are bathing.
People. Human bodies naturally give off heat, which is why the amount off people in your family is something we take into account when sizing an air conditioner for your home. This is a source of heat gain that’s usually out of your control, but you can help minimize it by spending more time outside, especially when you are hosting a lot of guests.

The Effects of Air Leaks

In an ideal situation, your home would be completely sealed so that cool air from your air conditioner could stay inside and warm outdoor air would have no way of getting indoors. In reality, however, many homes have small cracks and openings (especially around windows and doors) that allow air to flow in and out of your home. Today we’re going to talk about the effects of these home air leaks and what you can do to avoid them!

Effects of home air leaks

Uncomfortable rooms. Rooms with significant air leaks can be extremely hard to keep comfortable. That’s because outdoor air can travel through the leaks and warm up a room, while conditioned air can escape out through the leaks. This is the most problematic in rooms with a lot of windows and/or exterior doors.
High energy bills. Because air leaks warm up the rooms in your home, your air conditioner has to work harder and consume more energy to compensate for them. This can lead to expensive energy bills, especially in the dog days of summer.
Poor air quality. The air that’s delivered to your rooms is filtered by your air conditioner’s filtration system. If your home has air leaks, unfiltered air from outside can seep through the cracks and cause contaminants to build up in your air. This is especially problematic during allergy season when there are a large amount of allergens in the air outside.
How to prevent home air leaks

The best way to prevent home air leaks is to inspect your home for leaks and seal up any ones that you find. A good place to start is with your doors and windows. Examine the frames around your doors and windows and see if any light shines through from the other side. If it does then you have found a leak. In addition, feel around your doors, windows and exterior walls for any signs of drafts. If you can feel air blowing through, then you have definitely found a leak.

Air leaks can be sealed in a couple of different ways. You can use caulk to plug up any holes that you find, while you can use weatherstripping around the moving parts of your doors and windows to ensure that they remain tightly sealed. For any other questions call 3D Air Services at 205-664-3501 or email us @

Air Conditioner Estimate

What to Look for in Air Conditioner Estimates from Birmingham Area Contractors?

A new air conditioner is a big investment for your home, and the cost of your system will vary depending on a number of different factors. That’s why air conditioning contractors provide customers with estimates for the cost of new systems. Unfortunately, not every contractor provides a good or trustworthy estimate. Today we’re going to help you ensure your estimates are performed right by talking about what to look for in air conditioner estimates from Birmingham contractors!

What is an air conditioner estimate?

An air conditioner estimate is the projected cost of installing a new air conditioner in your home. When performed correctly, an estimate will accurately tell you how much you can expect to pay for your installation and will not leave out any hidden fees. You can use an estimate to help budget for your new system and also to help you choose the right air conditioning contractor.

What to look for in an air conditioner estimate

Free and no obligation. First and foremost, you should not be charged for an air conditioning estimate. This should be a free service that includes absolutely no obligations. If a contractor tries to charge you for an estimate, move on to someone else.
Load calculation is performed. A low-quality contractor might present you with estimates before actually performing any sort of measurements on your home. This should be a huge red flag. The only way for a contractor to know what size of air conditioner is right for your home is to perform a cooling load calculation. Because the size of your system will directly affect its cost, you should not accept any estimates from contractors who do not perform a load calculation on your home first.
Various efficiency options are presented. Air conditioners come with a variety of different efficiency ratings. The higher the SEER rating of a system, the more that system will cost. Your contractor should provide you with a range of different efficiency options so that you can compare them and make a more informed decision. In addition, your contractor should be able to explain the long-term savings that a higher efficiency system can provide.
A time table is provided. Your estimate should give you an idea of how long the installation will take.
Options for advanced features are laid out. Your estimate should include options for advanced features like a zoning system, variable speed air handler and two stage cooling that will all help improve comfort and efficiency levels in your home.
Financing options available with approved credit through Alabama Power, Alagasco, Wells Fargo, and with no credit required through Microf .
Estimate is in writing. Estimates should not be handshake or verbal agreements. Instead, an estimate should be provided in writing before any work is performed. That way, you can refer to the estimate if a contractor tries to charge you much more for your installation than what was originally quoted.
