HVAC Repair Rapid City SD | Call D & R Service

A common local issue is frozen heat pump components during cold snaps. First, check if the outdoor unit is covered in ice or if airflow seems blocked. Switch your thermostat to 'emergency heat' to maintain warmth in your home, then call us. Our technicians are available 24/7 for emergencies. We'll diagnose the issue, which could be a faulty defrost cycle or refrigerant problem, and get your system running efficiently to prevent further damage and restore comfort.

For optimal performance in our Black Hills climate, we recommend scheduling preventative maintenance for your heating system in the fall and your air conditioning in the spring. This bi-annual service allows our certified technicians to clean components, check for wear, ensure proper airflow, and verify safe operation—including checking for potential carbon monoxide risks with gas furnaces. Regular maintenance helps prevent costly breakdowns during extreme temperatures and keeps your system running efficiently.

We carry and are certified to service a range of well-known, reliable brands for both residential and commercial HVAC and refrigeration equipment. This includes furnaces, air conditioners, heat pumps, water heaters, and commercial units like walk-in coolers and ice machines. During a consultation for installation or replacement, we can discuss options that fit your specific needs, budget, and efficiency goals for your Rapid City home or business.
