"Butch called back right away. Came out in a timely fashion. Got one unit working. Then he said the main board was malfunctioning on the downstairs unit and would have to be replaced. It would cost 1200 or 1300. But if we spent a little extra on a service contract he would wave the trip fee and it would be 1100 something. Okay. We did that. It was too late for him to get the board that day so he came out the next day to install the board. But the unit still didn't come on. He said the thermostat was bad and it would we 300 to 500 to replace the thermostat depending on what we wanted. My husband told him we could do that ourselves. Just by pass it and get the unit working. Then he came down and said that the blower motor was out and it would be 1800 to replace the blower motor or 2400 to just replace the whole unit and then we'd be under warranty again. I told them I wanted a second opinion before we did that. I called Ed & Sons they came out, confirmed that we did need a new thermostat. And said they could rebuild the blower motor for around 100$. I ordered two new thermostats for 300 for both of them and my husband installed the thermostats. The work they did was fine. But I felt like they were more of the school of let's just replace parts until it works or we can sell them a new unit. Rather than what can we fix."

"July 2017 OAT +101 (F) -one of my AC units stopped working. I called them at 3:30 P.M. Wed. and they tried to to help me that same day , but of course, with the temps in the 100's they were very busy with other emergencies. They got to me first thing the next day and had my A/C up and running within a few hours. Great service! Great communication! I would definitely recommend them. They will do all my future HVAC work."

"After moving into our house, the ducts desperately needed to be cleaned. I was able to get an appointment with Go air duct quickly and they were fantastic to work with. Noah is the best! He was amazingly professional, friendly, and was very honest about what we needed done and what we could hold off on. I am really happy with how clean it came out. Thanks a ton, Tommy"

"I returned home Sunday afternoon to discover my A/C had been broken for awhile. My thermostat inside read 99°. Jose quickly responded and I had a temporary fix with A/C flowing. Jose installed a brand new A/C system 2 days later. His pricing was very fair, and I am already reaping the benefits of a lower monthly electric bill."

Heating and Air Conditioning FAQs, answered by experts

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.
