San Diego's Most Trusted Heating & Air Conditioning Specialists

We recommend following the 5,000 rule: Multiply the age of your system by the estimated cost of repair. If the total exceeds $5,000, or if your system is over 12-15 years old and utilizes obsolete R-22 refrigerant, replacing it with a high-efficiency 18+ SEER2 unit will yield substantial long-term electricity savings.

Yes! San Diego's moderate coastal climate is ideal for heat pumps. Modern inverter-driven heat pumps efficiently cool your home during summer and extract heat from outside air during mild winter months, operating up to 300% to 400% more efficiently than standard gas furnaces or resistance heaters.

We recommend bi-annual tune-ups: once in early spring for your air conditioning system and once in early autumn for your furnace or heat pump. Regular maintenance prevents unexpected seasonal breakdowns and maintains manufacturer warranty compliance.

Ductless mini-splits connect an outdoor condenser to quiet indoor wall-mounted handlers using thin copper lines. They eliminate ductwork loss, allow individual room temperature zoning, and are ideal for coastal homes, historic renovations, or room additions.

To curb high SDG&E rates, replace air filters every 30-60 days, utilize smart programmable thermostats to pre-cool before Time-of-Use (TOU) peak pricing hours (4 PM - 9 PM), schedule annual coil cleaning, and upgrade to variable-speed HVAC equipment.

Yes! Under the Inflation Reduction Act (Section 25C), qualified high-efficiency heat pumps can earn up to $2,000 in federal tax credits. Additional local utility incentives and TECH Clean California rebates are available—our team handles all paperwork to maximize your savings.

We recommend MERV 11 to MERV 13 pleated air filters for residential HVAC systems. They capture fine PM2.5 wildfire smoke particles, dust mites, pollen, and pet dander without restricting system airflow or damaging your blower motor.

Coil icing and warm air blowing are typically caused by restricted airflow (dirty air filters) or refrigerant line leaks. If ice builds up on your copper refrigerant lines, turn off the system immediately to prevent compressor failure and call Prime HVAC Services for diagnosis.
