"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!"

"During this very cold winter, I wanted my HVAC system checked out, esp after the fan were frozen in place before being de-iced by me. The service person was great. He checked my system and was able to answer my questions. Thank you."

"Mast Electrical Services installed three outdoor GFCI outlets in the soffit of my house. I was worried that because there was no flooring in my attic that it would be an issue, but not for Mast Electrical Services. They arrived on time, performed professionally, did an outstanding job, and all for a very reasonable price. They even answered some questions regarding running low-voltage wiring through my walls that enabled me to perform that work myself. I strongly recommend Mast Electrical Services for your electrician needs."

Heating and Air Conditioning questions, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

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.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.
