What if Something Goes Wrong with my New System?

When we buy cars, we always worry, what happens later? If I have an engine light come on, what is covered?

At Calvin’s Climate, we understand that purchasing a cooling and heating system for your home is a similar process.  In the Flower Mound, Highland Village and Lewisville areas, our homes are a source of pride and comfort.  The last thing we want to worry about after upgrading the comfort equipment in our homes, is a breakdown.

Let us help you relax.

We prefer to install American Standard equipment,  due to its reliability. In addition, we offer unsurpassed care for all of our new system installations.  For two years, we include our Family Circle Maintenance Program.

We come and clean and service your units twice per year, once in the spring and again in the fall, complimentary.  If you ever have a problem with your system, you are our priority.

We’ll do the right thing.

From doing only the best quality installations with city permits and insurance coverages and lots of extras that others don’t include, to offering unsurpassed warranties; doing the right thing for our customers has served us well since we started in 2000.  It’s something we don’t plan to change.

How HVAC Works

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.

It’s time to clean your thermostat screen

While you’re busy sanitizing everything in your house, take a minute to clean your thermostat as well.

If you have a model 824, 850 or 1050 thermostat, it comes with a “Clean Screen” feature, which gives you 30 seconds to wipe it down while the touchscreen is deactivated. That way, you don’t have to worry about pushing any buttons or changing any settings.

“Clean Screen Mode” can be found by going to Menu > Settings > Screen > Clean Screen.

Air Conditioning Technology

No matter what thermostat you have, we recommend using a non-abrasive cloth and a mild, ammonia-free cleaning solution.
