"Had a new Heating and AC unit put in. These guys are absolutely awesome. They are friendly and considerate and work very hard to make sure everything is done right. They consistently kept me updated on what was going on and explained everything they were doing in detail. If there was something I didn't understand, they happily explained what they were doing. They are a new company but don't let that fool you. The owner has many years of experience and knows what he is doing. I will only ever use these guys for all of my HVAC needs in the future. So glad I got them to do my HVAC work! Thank you Eliseo and Orlando! You guys are the best."

"I had just posted my house for sale when the AC decided to stop working. I opened Angie's List ready to call all the local HVAC companies to find out which one could come soonest. We already have a showing tonight and didn't want the house to feel like a sauna. I explained this to John, and though he said he was booked out for weeks, he said he'd try to shift things around to get to me by 2PM. He called at 10AM and said he could be here in 30 minutes. He was very professional and pleasant to talk to and work with. He quickly found the problem and had the parts available so he was able to make repairs immediately. I appreciate that he explained how the original installers could have done a better job with the drain line which would have prevented the cause of our outage. He then proceeded to redo the drain line the right way. Would gladly hire Absolute Temp Control again."

"Home Pro Heating and Air did an excellent job fixing my A/C. From the moment I called, they were professional, responsive, and straightforward. The technician arrived on time, diagnosed the issue quickly, and explained everything in a way I could understand. The repair was done efficiently, and my air conditioning has been running perfectly ever since. Their pricing was fair, and the level of service was outstanding. It’s rare to find a company that’s both honest and highly skilled, but Home Pro proved to be both. I’m extremely satisfied and would absolutely recommend them to anyone needing HVAC work."

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.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

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.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Assessing location for airflow, convenience, and minimal noise impact.
