"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."

"I had such a dismal experience with local carpenters, who lied to me and did not understand the basic HVAC. I found this company when I was searching for a better business, and they have all been excellent. From their company representative who came out to give me a bid, to the techs that cleaned my vents for me, everyone has been professional and helpful. I really appreciate that their technicians are on time and clean our office with care -its worth every penny"

Heating and Air Conditioning FAQs, answered by experts

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own. 

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, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
