"I’m overly pleased with the work that Wells HVAC provided me. The heating/cooling in my home was antiquated, inefficient & unreliable. However, Michael & his expert-tech remedied those solutions for me. In addition to that; they were punctual in arrival times, they were neat & tidy, and something that stood out to me was their politeness! It feels so good not to be stressed about an unreliable climate & atmosphere in my home now thanks to Wells HVAC. I have, and will continue to highly recommend them to my friends, family, and associates. If you’re on the limb about getting a service done or whom to get it done by… Just call Michael, I promise there will be no regrets or disappointment!"

Heating and Air Conditioning questions, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
