Heating Repair

There is nothing more frustrating than a heater malfunction in severe weather. The situation can become much worse if you choose the wrong contractor to repair your heating system. Our service department is well equipped and staffed by professionals who know how to diagnose the problem and quickly fix the unit with minimal downtime. We provide 24/7 service for emergencies, and you’ll always talk to a live person who can help troubleshoot the problem before dispatching a technician.

AC Repair

Summer weather is tough on air conditioners, and they always seem to break down when the temperature is rising. At Guardian Heating & Cooling, we know your daily routine is severely disrupted when your AC system isn’t working. All of our service techs have the tools and knowledge to diagnose your unit and replace the faulty components quickly. Since we only use genuine factory-authorized parts stocked on our service vehicles, most jobs are finished in one visit. To avoid future problems, don’t forget to ask about our affordable maintenance plans.
