"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!"

"Mark from Duke's Electrical Services was recommended by a friend in the home improvement business whose referrals have always been A+, and Mark certainly lived up to that reputation. Mark and his son were professional, punctual, and communicative. They texted before arriving and showed up exactly on time. Mark performed a thorough electrical inspection, took photos, and reviewed everything with me so I understood the condition of our system. I also asked about a few smaller projects, including a dock light switch and a deck remote-control switch that weren't working. Mark followed through on his promise to return, contacted me within a week, and scheduled the repairs. During that visit, I added two more switch replacements, and they completed all three jobs in under an hour. What impressed me most was their attention to detail. After finishing, they vacuumed the work area. As someone who appreciates cleanliness, that meant a lot. Professional, efficient, cleanliness, very rare find."

Heating and Air Conditioning questions, answered by experts

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.
