Frequently Asked Questions

How do I prevent pipes from freezing in my Newtown Square home?

Many older homes in the area have pipes in uninsulated crawlspaces or near exterior walls. We recommend insulating these lines and keeping a slow drip of water running during extreme cold snaps to relieve pressure and prevent costly bursts.

Can you install modern AC in a home with radiator heat?

Yes, we frequently install ductless air conditioner systems in Newtown Square homes that lack traditional ductwork. These systems are highly efficient and provide targeted cooling without the need for invasive renovations to your historic home.

Why should I consider a whole-home surge protector?

With the frequency of storms in our part of Pennsylvania, power surges are a common threat to expensive electronics and HVAC equipment. A whole-house surge protector provides a vital layer of defense that standard power strips simply cannot match.
