"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"

"This business is the company that bought the older Barrington Heating and Air Conditioning. I have relied on Barrington to service my house furnace and A/C for more than 50 years. They have come to my rescue more than once. My service technicians have become friends, not just repair people."

"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."

"Austin, Orin and James were great to work with. Due to raccoon damage to the attic insulation and ceiling drywall all old insulation needed to be removed and contaminated areas treated. They installed new soffit baffles between each pair of rafters, sealed all potential air leakage points (e.g. around can light fixtures), ran all new insulated bath fan ducts (4) to soffit mounted valved vents and blew in all new insulation. Cost was very reasonable. Overall excellent value. Austin provided my insurance company with all necessary information so the claim was quickly settled to my satisfaction. Highly recommend Greenlink Energy Solutions."

Air Conditioning questions, answered by experts

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. 

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
