Stay Cool When Summer Temperatures Spike

A broken AC during a San Marcos summer is more than uncomfortable. It can put your family’s health at risk. When your cooling system stops working, temperatures inside climb fast. Our air conditioning services get your system running again quickly. From AC repair and AC maintenance to full AC installation, our HVAC technicians handle it all. We also offer mini splits and attic blown-in insulation to boost comfort and energy savings.

Keep Your Home Warm Through Winter Cold Snaps

Central Texas winters can bring sudden freezing temperatures that catch homeowners off guard. A furnace that hasn’t been maintained could fail right when you need it most. Our heating services cover furnace installation, furnace repair, seasonal tune-ups, and ongoing furnace maintenance. Summit Air Conditioning & Heating makes sure your heater is ready before the cold arrives so you never have to worry.

Year-Round Comfort With Heat Pump Solutions

Heat pumps offer an energy-smart way to both heat and cool your San Marcos home. When they break down, your comfort and energy bills take a hit. Our team provides heat pump installation, repair, and maintenance to keep your system performing well all year long.

Breathe Easier With Better Air Quality

Dust, allergens, and pollutants build up inside your ductwork and circulate every time the system runs. Our indoor air quality services include duct replacement, duct repair, and smart thermostat installation. Clean ducts and modern controls mean healthier air for your whole family.

Reliable HVAC Solutions for Local Businesses

A failed commercial HVAC system can disrupt operations and drive customers away. Our commercial HVAC services cover both AC and heating for offices, retail spaces, and other buildings. We work efficiently to minimize downtime for your business.
