"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"

"Matthew and his crew were extremely professional and efficient. The work was completed on the day scheduled and they cleaned up after themselves. Heat pump works great and they were able to direct me to an Effeciency Maine site where I received a substantial discount on the installation, equipment and cleaning plan!! Great company to do business with and will recommend them to family and friends. I will definitely not hesitate to use this company again if the need should arise!!"

Customers say: Quick response

"Karl was very professional. Came out to quote the job and started shortly thereafter. Even though the install took more man hours than anticipated, we came to a new, fair agreement and am very happy with the results. New HVAC system is top notch. Would recommend to anyone looking to covert to heat pumps."

Heating and Air Conditioning FAQs, answered by experts

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.
