How to maintain a heat pump

Homeowners who have heat pumps systems in their homes know the many benefits they provide. While it is economical to use a heat pumps split system, they still need to be maintained like a traditional gas furnace.

By implementing just two simple habits, you can deliver the type of care necessary for your heat pumps to work efficiently while extending its lifespan.

Heat Pumps Maintenance
Heat pumps maintenance is an important part of caring for your heating system. Heat pumps maintenance should be done twice a year, in between major seasons.

Maintenance helps prevent expensive repairs and permanent damages. Since the heat pumps system works around the clock, it is exceptionally important that specialized care is provided.

During the maintenance call, your heat pumps contractor:

Removes buildup and obstruction inside the heat pumps split system
Tests safety switches, gauges and meters
Resets pressure settings on refrigerant coils
Tests motors and belts
Measures airflow
Changes the air filter
Maintenance also gives your heat pumps contractor the opportunity to speak to you about how the system has changed. Because the system changes as it ages, homeowners should also adjust their usage pattern accordingly.

Clean Out the Heat Pumps’ Outdoor Unit

The heat pumps system relies on outdoor air to adequately heat and cool the home. So, it is important that the heat pumps unit is located in the right place. When it was first installed, your heat pumps contractor most likely chose the best location. However, with time, outdoor settings change.

Homeowners might find that their heat pumps unit has been covered with broken branches, is near a trash bin or around other organic waste. This may hurt the efficiency of your heat pumps system since it has to work doubly hard to filter through the mess. It might also create resistance in airflow, slowing down the air conditioning process.

For these reasons, homeowners are encouraged to closely monitor their heat pumps’ outdoor unit. Position the heat pumps off the ground and away from any plants, trash, dirt or even snow. Clearing the area around the heat pumps also prevents damages.

Keep drains and pipes free of buildup. As efficient as the heat pumps system is, any type of blockage could easily reduce efficiency up to 25 percent.

If you are unsure how to handle your heat pumps and care for the system from home, contact your HVAC contractor. He or she can provide additional help to make your heat pumps last.

New Furnace Mistakes.

Are you in the market for a new furnace? This can be quite a daunting process! There are many different furnaces to choose from, and the system you select (as well as the contractor you work with for the installation) can have a big impact on your home’s comfort and efficiency levels for years to come. Today we’re going to make the process a little easier by talking about some of the biggest furnace buying mistakes you can make and help you select the perfect heating system for your home!

4 big furnace buying mistakes to avoid when you’re in the market for a new system

Working with a low-cost, low-quality contractor. In many ways, choosing the right contractor is the most important part of buying a new furnace. There are low-quality contractors out there who will try to offer extremely low installation prices just to get your business, only to perform the installation poorly or install a system that isn’t sized right for your home. The mistakes that a bad contractor can make during a furnace installation will end up costing you a whole lot of money in the form of future repair costs and high heating bills. A high-quality contractor like 3D Air Services will match your home with the perfect heating system and perform the installation the right way so that your system will operate at its peak efficiency and performance levels.
Focusing on price alone. Another big mistake that some homeowners make is focusing too much on the initial price of the furnace that they choose. Although high-efficiency furnaces cost more up-front than mid-efficiency systems, a furnace with a high AFUE rating will save you money in the long run because it will result in lowering monthly heating bills for years to come. We know that the up-front cost of a furnace is important, but it should not be the only factor you consider when choosing a system.
Not thinking about fuel-type. Furnaces can use a variety of different heat sources, including natural gas, electricity and oil. Unless you install a heat pump, which is a highly-efficient electricity-powered heating system, the most efficient heat source for furnaces is natural gas. If your current furnace is not gas-powered, you should consider replacing it with one that is because natural gas is the least expensive heat source.
Not considering signing up for a maintenance agreement. You will spend good money on your new furnace, so it’s important to take good care of it throughout its operating life. One of the best ways to do that is by signing up for an HVAC maintenance agreement. 3D Air Services maintenance clubs include annual tune-ups for your furnace, in addition to other great time- and money-saving benefits. Signing up for a maintenance agreement will maximize your investment in your new system and ensure that it runs great for years to come.

10 Air Conditioner Mistakes

In general, we don’t have to interact with our air conditioners a whole lot. Our thermostats tell our systems when to turn on and off, so the cooling process is basically on autopilot. However, there are some common mistakes that homeowners often make during those times when we do have to interact with our air conditioners that can have big effects on your system’s efficiency and performance levels. Today we’re going to talk about 10 common air conditioner mistakes to look out for so that you don’t fall into the same traps that many other homeowners often do!

10 air conditioner mistakes to avoid

1)Skipping air conditioner tune-ups. Regular tune-ups aren’t just for fixing problems, they are also for taking care of important maintenance tasks that need to be performed every year in order for your system to work at peak efficiency. If you skip out on a regular tune-up, you’re at a big risk of a breakdown this summer and your cooling bills will likely be higher than they would be if you had a tune-up performed.

2)Not changing dirty filter. A dirty filter is responsible for a huge amount of common air conditioner problems. Alot of homeowners completely forget their filters and leave the same filter in for months even years, while others simply forget to change their filters. Your filter should be checked and/or changed once per month.

3)Installing an oversized system. You might think that “bigger is better” when it comes to air conditioners, but that is wrong. If you install a system that’s too big for your home, your home will be uncomfortable due to big temperature swings, uneven cooling and high humidity.

4) Turning down the temperature. Some people have the idea that the lower you set your thermostat, the faster your home will cool down. This is not true. Your home cools down at the same speed no matter where your thermostat is set. If you turn down your thermostat, you can forget to change it back, which will waste a lot of energy and force your system to work extra hard on days that are likely already hot.

5)Ignoring problems. We know that summers can be busy and it can be hard to find the time to call for an air conditioner repair. But the longer you ignore a problem, the worse that problem will get and the more expensive the repair will likely be.

6) Going with the cheapest contractor. When you are choosing an air conditioning company for an install or repair, it can be tempting to choose the cheapest contractor you can find. This is a huge mistake, because the cheapest contractor is almost always the lowest-quality. Choosing a highly-reputable company like 3D Air Services is much better in the long run because your system will be properly taken care of and you won’t have to spend money on problems that are caused by the work of untrained and unqualified technicians.

7)Placing appliances close to the thermostat. If you place any lamps or other appliances that put off heat near your thermostat, it can cause your thermostat to think your home is hotter than it actually is. This will keep your air conditioner running longer and harder than it needs to, which can make your home too cool and will waste power.

8)Waiting too long to replace your system. Many homeowners want to get every last day out of their old and inefficient air conditioners. The problem, however, is that old air conditioners will inevitably break down and leave your home with no cool air. In addition, old air conditioners are a a lot more expensive to run than new, high efficiency systems.

9)Blocking or closing your air vents. There is a common myth that by closing vents in unused rooms in your home, you can save energy by not cooling those rooms. However, this is not an effective energy-saving strategy, and it can actually lead to problems with efficiency and performance issues.

10)Trying to cover your outdoor unit. Some people try to make their air conditioners’ outside units blend in with their yards by planting trees, flowers and other plants around it. This is in-correct, because it blocks the airflow to the outside unit and makes it more difficult for your A/C to cool your home.

My air-conditioner is frozen?

Have you ever checked the indoor piece because you suspected a problem and found it was frozen up? What causes this? This is a more common problem that you might expect. Here is  4 things that can cause you’re system to freeze up.

– Low Refrigerant. The refrigerant in you’re air-conditioner actually absorbs heat from you’re homes air and transfers it outside. image imageIf you’re system has a refrigerant leak, there won’t be enough refrigerant available to adequately remove heat from the air, as a result the evaporator coil will stay cold and freeze up.

-Poor airflow. Even if your air-conditioner has enough refrigerant, it can freeze over when there isn’t enough return air blowing over the coils. This makes sense when you think about it. The heat that your evaporator coils absorb comes from the air inside your home. If something is blocking airflow (such as a dirty air filter, closed air registers or issues with the blower motor) then there won’t be enough heat available to warm up the coils.

-Dirty coils. When dirt builds up on our evaporator coils, it creates an extra layer between the warm air that’s blown over them and the refrigerant inside the coils. This makes it much harder for heat to transfer between the air and the coils, which causes the coils to get too cold and freeze up.
Cold weather outside. This can be a problem during the springtime when temperature levels can rise and fall unpredictably. If your air conditioner is operating when the temperature outside is below 60 degrees, your coils have a chance of freezing over.
How can you prevent your air conditioner from freezing up?

The best way to prevent your air conditioner from freezing up is to schedule a tune-up every year. During your tune-up, we’ll check your system’s refrigerant levels, inspect the blower motor and clean your coils so that the heat transfer process can execute with ease. In addition, make sure to change your air filter regularly and keep all of your air registers open and clear of obstructions so that your system doesn’t operate with any airflow issues.
