With Mersey Heating and Cooling, you know exactly what you’re going to get. We guarantee it.

Why Choose Us?


No Loopholes™

Your satisfaction is our priority. If you’re unsatisfied with our work, products, or materials within 2 years of the installation date, we’ll do our best to make it right. No Loopholes™, just accountability.


No Hassles™

We stand behind the work we do. If within two years of your installation, you find yourself without heat due to a system breakdown, we will repair the issue within 24 hours of your call, or we’ll offer you $1000 for your inconvenience. No Hassles™, just results.


Just Right™

Consistency is key. If your system doesn’t give you the set temperature you desire within the first 5 years, we’ll make the necessary adjustments, up to and including replacing the system at no charge. No fluctuations, Just Right™


We Respect You™

We hold our technicians to the highest possible standard, and expect everyone on our team to respect you, your family, and your property. If we fail to live up to these standards, we will gift you with our full 5-year system check-up package at no charge. We Respect You™.
