"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"Ray was very responsive and professional since my first contact with him. He came out early the next day to diagnose my broken AC and walked me through the testing stages and explained what he was doing, how it works, and why. He tried several methods to get the system up and running but ultimately, we had to replace the old unit. Since we were in a 100 degree heatwave, Ray was mindful of our situation and came early the next day to install the new unit within an hour. Very fortunate to have a seasoned professional like Ray to help us amidst the heat and Covid. I would highly recommend him to anyone looking for central AC work."

Air Conditioning questions, answered by experts

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

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.
