"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."

"Justin is great! He is communicative, prompt, and thorough. I contacted him as we were having an issue with our boiler. I appreciate that he fully explained the work he was going to do and took the time to ensure the issue was resolved. I have dealt with many contractors both professionally and in my home and Justin is one of the good ones. I would definitely recommend him to my friends and family."

"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

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.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.
