Replacing Your HVAC System

Replacing Your HVAC System

If you’re replacing your HVAC system, when you select Calvin’s Climate, it’s more than just a change of equipment. It’s a design that takes into account your preferences, likes and dislikes, as well as properly sizing the unit for your space.

Have hot and cold rooms?  No problem.  We’ll make sure your unit is properly sized by performing a heat-load calculation on your home.  Our expertise will ensure your unit is installed to perform at optimum factory specifications, and not simply replacing your current design.

Looking for an ultra-quiet unit? No problem.  Not only will your outside unit be quiet, but we’ll make sure the ductwork is properly designed for maximum airflow in your home, resulting in quieter operation.

Want to adjust the temperature without getting out of bed at night?  Simply use your phone app with our professionally installed Wi-Fi thermostats and adjust the temperature from anywhere with an internet connection.


Let us discuss your needs and design the right system at the right price for you. You’ll be increasing energy-efficiency, lowering utility bills and upping your comfort level. We perform a heat load calculation and submit permits to the local jurisdictions ensuring your system is installed with the utmost quality. Couple that with our unparalleled service warranties and you’ll be glad we went the extra mile to ensure your satisfaction.
