"Our mini-split A/C wasn't cooling after we stopped using it to heat the house. We were in the middle of a local heat wave, but Joshua was able to come the day after we sent in our request for service. He was very professional and explained all of the options for getting things cooling again. After checking out the unit, he added several pounds of refrigerant which fixed the problem. His rates were very reasonable (even during the heat wave) so we'll use his company in the future and highly recommend him to anyone needing similar service."

"I was contacted right away and they were at the house within an hour of my returning their call. They knew exactly what to do, had all the right equipment and were very knowledgeable about duct cleaning. The job was diagnosed, and completed in 30 minutes which included leaving the work site neat and clean. Great job!"

Air Conditioning questions, answered by experts

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
