Trusted, Award-Winning Air Conditioning and Heating Services in Denver.

With over 40 years of providing the greater Denver area with the finest residential indoor air quality, temperature, and humidity levels, hardly any job is beyond our skill level or budget range. With over 100 years of combined experience, our technicians have worked in homes of virtually any age or condition. Sanders & Johnson is a proud dealer of Bryant premium air conditioners and furnaces, a Carrier Corporation brand. Bryant consistently ranks as one of the top residential comfort equipment lines in the world.

While there are certainly differences in each brand of home comfort appliances, we know that the quality of the install is far more important than the brand itself. In fact, if correctly and professionally installed, a lesser brand unit can perform significantly better than a top brand which was improperly installed. Of course, a top-tier brand like Bryant paired with our professional installation is always the best choice for long-lasting and efficient comfort.

We operate as a team of local, community-minded people which means we treat you like a neighbor instead of a sale. That means top-quality installations and genuine care for your comfort and health. From the simplest air quality and mold checks to complete retrofit installs, our experienced and friendly staff will leave you no mess or headache, just comfortable, clean air.
