$10,000 Mass Save® Rebate
We had a great experience from start to finish! The installers were professional, courteous, prompt, efficient, as well as clearly knowledgeable and experienced. We appreciated how considerate they were of the fact they were in our home. They took time to answer any questions we had and for whatever explanations were needed. And we love having central AC!!

Frequently asked questions

Is it worth getting a heat pump?

There are numerous compelling reasons to consider investing in an air source heat pump:

- Enhanced Comfort: Upgrading to a heat pump provides superior comfort compared to traditional heating systems.
- Annual Savings: Heat pumps offer substantial annual savings on energy costs.
- Advanced Technology: With cutting-edge technology, heat pumps ensure efficient and effective heating.
- Lower Maintenance: Heat pumps require minimal maintenance, reducing hassle and costs.
- Safety: Unlike traditional heating methods involving combustion, heat pumps eliminate the risk of fire hazards in your home.
- Government Rebates: Take advantage of available government rebates, such as Mass Save and Con Edison, which may change annually.
- Utilizing Pre-funded Rebates: These rebates have already funded through your electricity bill, making them a valuable resource.
- Efficiency: Heat pumps are four times more efficient than boilers, resulting in significant energy bill reductions.
- Extended Lifespan: With an average lifespan of 18 years, heat pumps offer longevity nearly double that of typical gas boilers.
- Environmental Benefits: Heat pumps produce 75% fewer emissions than traditional heating systems, making them a much more environmentally-friendly choice.

How much do heat pumps cost to run?

Monthly costs vary based on usage, the number of people in your household, and other factors. However, homeowners who install energy-efficient appliances report energy cost savings of 25% or higher.

Is a heat pump noisy?

The outdoor unit of the heat pump does make some noise, although it is only as loud as your refrigerator or a quiet washing machine.

The indoor parts of the heat pump - the circulation pump and immersion heater - might make a very small noise, but it will be no louder than a whisper.

When will you install my system?

We can install your system as soon as 7 days after you put down your deposit.

Who is doing the installation?

One of Tetra's fully vetted, top-quality installers will handle the job. We only work with the best local pros.

Will I be charged extra if something unexpected happens on installation day?

No. Our pricing is firm. We’ll confirm the cost of your project after your walkthrough and there will be no changes in price after that point—no matter what happens on installation day.

You haven’t been to my house. How do you know what I need?

We can make specific recommendations based on the information you provided and our experience installing hundreds of systems. Plus, the pre-installation walkthrough gives us an opportunity to confirm the recommendation.
