"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

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

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.
