"These guys are the best! They taught me so much about my home HVAC system, both the pros and cons. They take so much pride in the results they provide it is almost as if they were the ones that installed the system in the first place even though they weren't although i wish they had because we definitely would not be having the issues we are having had these guys been in charge during the installation."

"It was late at night when we realized our water heater blew and flooded our basement like a swimming pool. We had to find a plumber and fast. we came across SWB he was out here within 30 minutes from our call the job he did was impeccable. He went above and beyond he went and got us a new water heater, installed it, and then stuck around to help us clean up, Since then we’ve used him for several other projects. Every time the professionalism came with him I would highly recommend him 100%."

"Techs were very nice. Took time to put mats down on my carpets to keep them clean. Explained how to operate the heat pump and gave suggestions on how to make it function most efficiently. Everything was cleaned up before they left, they even vacuumed! So glad I went with LaPlante for my heat pump! Bev"

Heating and Air Conditioning FAQs, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

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.

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.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
