"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"

"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."

"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!"

Air Conditioning questions, answered by experts

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.
