"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

"The technician came out after 11 pm when other companies could not until the next morning. Mr. Meriweather, was very courteous, and fast with the repair. I will definitely call G & R in the future for any heating and air conditioning needs."

"I had the best experience. It was a super hot day and my air conditioner stopped working (it had given me problems in the past and i knew it was time for a new one). Called Keith Lascos heating and cooling; told them the situation and they said they would be out by my house around 5pm. Not only did they show up on time but they completed the installation the very same night. The price was fair and they answered all my questions and ever since I have had no problems with my AC. It was probably the best experience I've ever had with a HVAC company."

"When our air-conditioning went out during a stretch of 90 plus degree weather, Jeff answered our call and came out the same day to fix our unit! He also followed up to ensure we were satisfied with his service. We could not be more pleased with his service!"

"I noticed this deal of Air Duct cleaning for unlimited vents and called Angies List customer service to ask about the deal and make sure that my one furnace with 3 zones would fit this deal and got all my questions answered; then I purchased the service deal and within an hour or so, I was called by the service company (LOWE'S Air Duct Cleaning Inc) and told that they are working in my area today, and have an opening in the middle of the day since someone changed their appointment; I accepted the time; the service man (Milo) came on time, worked non stop for about 3 hours, where he opened each air vent for the incoming and returned air and cleaned. I have asked for a camera to be used in 3 air vents in order to see before and after cleaning, and noticed the difference. Milo was extremely kind, professional, and worked very hard to get things done in a reasonable amount of time given that I have about 27 air vents and returned air plus 4 long ducts in the basement that are coming from an into the one furnace; The service also included sanitizing and air freshening. I was extremely satisfied with the service, and would defenetly recommend the service to anybody."

Air Conditioning questions, answered by experts

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.
