"Angie, I was glad to find Advent on your web site. The technician did such a great job that I referred them to my friend who was having HVAC problems. Our A/C quit and I thought the problem was the thermostat so I changed it. The unit did not run. I wanted a company that served Eastern OK County & checked Angie's List on-line. Advent is in Choctaw OK and has a superior rating. I know why, now! The tech was running late and called to let me know, which I appreciate. When he arrived, I explained what I had done, saying that I had found the brown wire broken and reconnected it. He traced the wires and got the unit working. What really impressed me was that he doubled checked the unit at the heat pump and found that it was heating, not cooling. He went back to the furnace & thermostat, removed the brown wire, and reversed 2 other wires. He was very patient with me and answered all of my questions. I really enjoyed this experience. Two years ago, when I was very sick, I was "hooked" into a costly plumbing problem by a local contractor. I'll check Angie's List first. Oh, by the way, the original thermostat was defective and the one I installed was good. Thanks Angie, thank you Advent!!!"

"We have used Airco for annual maintenance on our home HVAC.  Our upstairs unit has had a coolant leak for a while.  Other servicers wanted to just top up the coolant, which has been getting more expensive with the rising cost of coolant and government regulations.  Airco checked for the source of the leak and determined that it was in the evaporator coil.  Government regulations do not allow replacement of just the coil since it uses R-22 coolant.  Airco sent someone to check our cooling needs, measured the area to be cooled and advised on the size of unit needed.  I asked about getting a larger unit with more heating and cooling capability but they said that it would be a waste of money (although it would have been more money for them).  They also advised on the different units available and credits available for installing a more efficient unit then what we had.  We selected a unit and within a week it was installed and operating.  It working great, and we're even letting it carry some of the load for our older unit which covers the downstairs zone in our home."

Heating and 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.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.
