We guarantee the lowest price

We charge up to $4,000 less than other contractors in your area and we do it without sacrificing quality.

We save money by ordering products and materials in bulk, and we pass those savings on to you.

We never mark up the cost of parts and equipment. With Tetra, you pay the same price as we do.

We secure manufacturer rebates on your behalf and give you those savings as an upfront discount.

The price we quote is the price you’ll pay. We never surprise customers with hidden charges later in the process.

We’ve replaced units for more than 5,000 homeowners and they're raving about us!

From removing the old system to installing a new Lennox, the entire process was easy and saved me thousands of dollars.

I was skeptical at first when I saw the price, but there were no catches at all. Very high quality work and excellent customer service.

The crew was very respectful and did high-quality work during the gas boiler job. They left my house spotless, too.
