Customers say: True professional

"Replaced the original AC Unit(at least 25yr old), added a new humidifier to furnace and a new smart thermostat. The original guy who did repair work, Phil, was knowledgeable but at the end of the day wanted to sell anything he can. He had convinced me I was able to get rebates through ComEd for upgrading AC unit and adding the smart thermostat. At this time, I have been unable to get any rebates because he failed to mention I need to also have a furnace that qualifies and there was no receipts on the thermostat to claim that rebate. The day of the install, the guys that were here, did great work. They installed everything and added a damper to furnace(which does not work that great). When the guy installed the thermostat, he installed the wrong one and i had to show him the work order for the correct one. He left and it took a week for him to return to install the correct one. He also left with all the boxes."

Air Conditioning questions, answered by experts

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
