DNA-heating-cooling.com is a FANTASTIC HVAC Company
If I could give DNA-heating-cooling.com a 10-star review, I absolutely would! Andrew and his crew are simply the best in the HVAC business. I have relied on DNA Heating & Cooling for the past two years for emergency service, minor repairs, and annual maintenance. They consistently provide outstanding workmanship, expert knowledge, fair and transparent pricing, and exceptional customer service. Their response time is incredible—especially during periods of extreme heat—and every customer is treated with respect, appreciation, and genuine care. My most recent experience was this morning after my air conditioner completely stopped working late last night. My Nest thermostat displayed an E74 error code, and with the current summer temperatures, I was extremely concerned. As a single senior citizen living in a two-story condo, the upstairs living area heats up quickly. I've had my sun-facing windows professionally tinted, installed a UV sunshade on my balcony to reduce the heat coming through the large sliding glass doors, added ceiling fans throughout the home, and even installed Blackout EZ Window Covers in the master bedroom—yet without air conditioning, it still becomes unbearably hot. I contacted DNA Heating & Cooling last night, and they responded early this morning. Andrew arrived within 20 minutes, diagnosed the problem, explained everything in terms I could easily understand, and had my air conditioning running again in no time. He never tried to sell me anything I didn't need and made sure I understood exactly what the repair involved. He finished in less than 30-minutes. Finding a company that is honest, knowledgeable, dependable, and genuinely cares about its customers is rare these days. DNA Heating & Cooling has earned my trust, and they will always be my first call for HVAC service. I highly recommend them without hesitation to anyone looking for a company that truly stands behind its work. Thank you, Andrew and your entire team, for another outstanding experience!
