Matt Stringer | First-String HeatingA Different Take on Heating And Air

A large percentage of the public view HVAC companies as “the heating company” or “the air conditioning company.” First String Heating’s owner, Matt Stringer, has a different take on what a HVAC company should do and what their responsibility to their customers. It’s not only our responsibility to heat or cool your home, it’s our responsibility to create an environment in which you are not just comfortable, but are safe and healthy. In fact we take this responsibility personally….

In 2011, Matt had a person close to him have a medical condition that caused a compromised immune system. In other words, if they got sick it would cause extreme medical issues. Matt dug in and began research into how he could create an environment inside their home in which the air was germ, virus, mold and allergy free. This research and passion has become the cornerstone of our business.

Our Mission: To provide our customers with the most up to date information and products in order for them to make the best decisions about both their indoor air quality and comfort.

Keeping you comfortable is our goal – call us for details. We can service your needs 24 hours a day, 7 days a week, 365 days a year.

We're here to serve your family

“Great service and excellent prices! Matt knows his stuff and is very customer friendly! He is honest and full of integrity!”
