Does a dirty coil affect your AC's cooling power? Absolutely! Your outdoor unit needs to "exhale" heat to keep your home cool, but if the coils are clogged up with dirt or grass clippings, that heat stays trapped inside the system. Getting your coils cleaned can actually improve your system's cooling efficiency by up to 15%. At M.D. Smith Heating & Air Conditioning, we can help clear away the debris to restore your airflow, lower your energy costs, and make sure your home stays perfectly refreshed all summer long.

We love finding ways to give back and connect on the greens! We were proud to sponsor a hole at the Stanislaus County PAL Annual Charity Golf Classic at Oakdale Golf & Country Club.

Supporting our local youth programs and building a stronger community is at the heart of what we do, whether we are keeping your homes comfortable or teaming up for a great cause.

Thank you to everyone who came out to play, volunteer, and make this event such a huge success. We look forward to many more rounds of community support together!
