"Made a call at 8am. Service technician arrived on time at noon and problem was solved AND fixed within a half hour. Technician was polite, kind, neat and clean but also got down to business quickly. Best part was... he had the part on his truck so there was no back and forth!"

"I currently own a rental property in Michigan. I often find it difficult to provide quality maintenance from afar, I live in Florida. When my tenant called and informed me that the furnace was not working, I immediately called Aire Serv. they have provided furnace tune ups for me in the past and have always provided top notch customer service. 
I worked with Bradley Bonniville, their furnace retail rep. He was patient and took the extra time to assist me with picking out the best furnace unit for my budget. He even took pictures of the final product and sent them to me when everything was done!
I highly recommend Aire Serv for any heating and air services. Thank you so much for the great customer service.

Air Conditioning questions, answered by experts

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
