"Cody showed up on time. Very polite young technician Appears to know his job well. He examined the indoor part of the system. Verified what initially indicated to his office that Freon is needed. He indicated that vents need to be cleaned before sealant and Freon can be added. Cost was as follows: $96 diagnostics + $203 for 1.5 pound Freon & labor + $60 another 30 minutes labor + $187 sealant (cost $27 on Amazon) = $545. System is working well. This cost is significantly higher than last service provider."

"I went from one outlet to three & from a floor cluttered with electrical cords to a clean space. Amir suggested additional outlets because I had created a fire hazard by using a multiple outlet power surger which probably caused the outlet & the power surger to blow out during a storm."

"The men were very professional and fair. They tried very hard to fix the AC but the unit was deemed beyond repair. It was leaking coolant somewhere. They said they could give me a very good deal on a new AC with all parts and labor included if and when I choose to replace the AC unit with them. Even though the unit was not fixed because it was frankly beyond repair, I am still satisfied by their dedicated effort, honesty and professionalism. I will most likely buy a new AC from One Hour AC of Naperville in the near future."

Air Conditioning questions, answered by experts

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.
