"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

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

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.
