"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"We had an HVAC issue develop on a Sunday. Contacted MSP and they scheduled a technician for Monday. They called us back an hour later and said they had a technician come available and asked if we were interested in getting serviced right away at the same service rate. The technician came by, fixed our system and even gave us some tips on our system. Very professional and informative. Excellent experience."

"August 29, 2012 was a very hot day, in fact I believe it was over 100 degrees.  My air conditioner suddenly stopped cooling and started making some very scary noises.   I called my usual A/C guys and they couldn't respond for two weeks, so I started looking on Angie's List.  I called several companies, but they were understandably too busy to respond right away.  When I called McLay Services, Inc. they promised to have a technician at my house within two hours. 
In the meantime, I shut the system  down because it was making very loud sounds and not providing any relief from the heat.  Todd arrived right on time (if not a little early, thank goodness!)  Of course, when we turned the system back on it was not making the noises and was providing some cool air.  Nevertheless, Todd did a very thorough check of the system inside the house and out.  He checked the filters, air flow and several other items that could be issues. 
About the time he was starting to explain that it was an older unit and probably just couldn't keep up with this type of heat, the noises started again.  Todd shut the unit off and opened it up.  He found that a contactor was burnt and no longer working.  He replaced the contactor, checked the operation of the A/C unit which was working beautifully and has been working fine ever since. 
I was impressed by the quick response as well as by Todd's knowledge, skill, professional attitude and obvious pride in his work.

Heating and Air Conditioning questions, answered by experts

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.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on
