Published national guides put common AC repairs, capacitors, contactors, and refrigerant work, commonly between $150 and $600, blower and control repairs higher, and full system replacement commonly between $6,000 and $14,000 depending on size, efficiency, and duct condition. Insurance rarely enters HVAC pricing: wear and failure are not covered events, appearing only after storm, lightning, or fire damage. San Marcos adds a local fact to the repair or replace math: units over 40 years old are still in service in this market, and repair money spent at that age buys seasons, not years. The written verdict after measured diagnosis, pressures, capacitor values, and temperature split, is the number that matters.
Diagnosis and repair of air conditioning that blows warm, runs without cooling, freezes up, or has stopped altogether.
After hours and same day heating and cooling service for no heat in a cold snap, no cooling in a heat wave, and the safety faults that cannot sit overnight.
Diagnosis and repair of furnaces and heating systems that click without starting, blow cold, short cycle, or have gone silent in cold weather.
Replacement of furnaces, air conditioners, and matched systems, sized to the house and its ducts, with repair versus replace priced both ways first.
Service and installation for heat pumps: systems icing up, blowing cool air in heat mode, leaning on auxiliary heat, or due for replacement.
Finding and fixing the duct failures behind hot and cold rooms: collapsed, disconnected, leaking, and undersized runs that waste the system you already own.
Seasonal maintenance visits that clean, test, and measure the system before the season that will punish it: coils, drains, electrical, and safety checks.
Design and installation of ductless mini-split systems for additions, garages, converted spaces, and homes where ducts do not reach or do not exist.
Assessment and improvement of indoor air: filtration upgrades, humidity control, and ventilation fixes for dust, odor, and allergy complaints that track with the HVAC system.
Common AC repairs run $150 to $600 in published national guides, and full system replacement commonly $6,000 to $14,000.
