Another successful furnace replacement for a great customer.
This home’s original furnace served reliably for over 25 years, but during inspection we found a cracked heat exchanger, which can allow dangerous carbon monoxide to enter the home.

We installed a new Trane furnace and safely restored reliable heat for the family. Comfort, safety, and quality work—every job.

We got a customer a new Aprilaire dehumidifier with ductwork installed in his basement this last week.
His basement kept having high humidity levels all year long and that known "musty smell" that kept traveling upstairs.
High humidity can potentially cause the wood and other parts of the home to form mold, mildew and rot.
It's important to keep your basement or crawlspace cool, dry, and regulated.
If you need a dehumidifier installed, either in a basement or a crawlspace or a whole home dehumidifier, give us a call and we will take care of all your needs!

Here we have a system that wasn't cooling
The system was so dirty and no air could pass through these coils!
Much needed Maintainance cleanings done on this 10 year old system.
This is what happens when systems are not properly and routinely Serviced!
Efficiency and cooling goes down!
Happy to get another good client fixed up and ready to go for this week's heat wave!
