"Clark Heating and Cooling was able to come to my house the same day that I called for a much lower service fee ($74) than other companies that I called. The Clark technician immediately knew what was wrong with my AC when he heard the unit and had the part replaced in under 20 minutes."

"This was my first time using Cardinal Heating & Air Conditioning, and it was a fantastic experience. I received a phone call asking me if I wanted to schedule my annual air conditioning check, and when I said yes, the scheduler informed me that she could have a technician come out that day. The technician arrived within a couple of hours and did a thorough check. Everything checked out, and I am ready for the hot summer months."

"We hired Hopper to replace a a 19 yo central AC system. They suggested a solution that saved was 14.3% less than ordering new system from the manufacter. And more importantly they had it installed 2 days later. Hooper is a well establised company that has earned its good reputation."

Air Conditioning questions, answered by experts

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

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.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.
