"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."

"O2 Kool servicers contacted me less than a minute after filling up my search on home advisor. I explained my issue and they came to my home within a few hours. They identified several problems that I wasn't even aware of once they began inspecting my HVAC unit. By 1:00 the next day they completely installed a brand new system. I was very pleased with the service from these gentlemen and would highly recommend them for any way needing HVAC service in the future."

"My wife and I were moving from our old townhouse to a new one. We found out that the HVAC system on the new townhouse was not working. So, of course, we called Texas Duct Service for help. They came out quickly, cleaned the system, and got it running again!"

"TeamEnoch work quality and cost were the best. Installation Evan and Richard took care everything much better than I expected. I have had American Home Shield who assigned several different contactors to fix my HVACs. Their (AHS contractors) work quality was poor (I would rate them as 2-star the most). I highly recommend TeamEnoch for HVAC work. In fact I will hire them again to install the 2nd HVAC for my house in the near future."

Heating and Air Conditioning questions, answered by experts

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.
