"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."

"I have nothing but good things to say about this company. My old Ac unit died on a Friday eve (Labor Day weekend) so I put in a service request. I was called near immediately and they came out the next morning to evaluate. By the end of the day the following Tuesday I had a brand new central air system at what I thought was a very fair price. The company owner JR came out several times to check progress. His installers were polite and professional and I was kept up to date on the arrival times and completion time estimate. Highly recommended."

"In the middle of a record heat wave my AC broke. AC repair companies have been very busy, but 02 Kool assured me they would make it out to me the same day, and did. Tech fixed my AC and had it cooling in a half hour. I can sleep at night thanks to 02 Kool."

"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."

Air Conditioning FAQs, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Yes, high-efficiency models reduce environmental impact with lower energy use.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.
