"I'd give Milo ten stars if I could! Another company quoted me an outrageous price for a major air conditioning repair that I did not need; Milo was completely honest and professional with me -- and fixed my air conditioning unit for one-tenth the price I would have paid the other company (whose estimator was "out on the golf course" when I called for help). So happy I found Maintenance Plus! Most definitely a company I would use again."

"Update 10/07 — I had an electrical issue with a washer/dryer (due to manufacturer error), and texted Tripped for help at 1pm. They had someone drive out immediately (my home is in a VERY remote location), and Marqus arrived by 3pm. The issue was fixed by 3:45pm. This company has EXCELLENT service, and I could not recommend them enough!"

"Justin and his assistant did incredibly high quality precision work removing an old furnace and installing a new furnace and AC. The price was very competitive and work was scheduled and completed quickly. It was amazing to see such high quality work after working with so many mediocre companies."

Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

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.
