Our Philosophy: What Would Mom Want?

At Thermo Tec Mechanical, our philosophy is simple yet profound.

Our Values

Our Core Values:
Integrity, Quality & Family

Integrity, trust, superior technology, the pursuit of grants and rebates on behalf of our customers, and repeated follow-ups. Those are our core values at Thermo Tec.

With over 40 years of experience and a family tradition spanning three generations, we treat every customer like family, providing the same high-quality service we would want for our own homes. Whether it’s installing heat pumps, furnaces, or air conditioning systems, we’re here to exceed your expectations and ensure your comfort all year round.

We recognize that new technology may be a struggle for some clients. That’s why we go above and beyond our initial installation to make sure your HVAC system is functioning perfectly and meeting your needs.

We also know that a new heating and cooling system is a significant investment in time and money. We’ll work with you to schedule your installation at a time that is convenient for you. Additionally, we’ll help you navigate grant paperwork, and work with auditors so you can qualify for government funding.

From installation to follow-up support and ongoing maintenance, we are dedicated to providing you with the highest quality service and ensuring that your HVAC system meets your needs both now and far into the future.
