Emergency 24 Hour HVAC Repair in San Marcos done properly
Emergency HVAC repair in San Marcos is about speed without shortcuts. Our after-hours technicians carry the same stocked trucks as the day crew, so a failed capacitor, contactor, condenser fan motor, igniter, or blower motor gets replaced on the spot instead of turning into a three-day wait. You get the price before the wrench turns, and you approve it. Nobody in this company is paid to take advantage of a customer at midnight.

On-site diagnosis with readings
The technician tests electrically and mechanically, identifies the failed component, and can show you the meter.
Step 3
Flat-rate quote, your approval
You get the repair price in writing before anything is touched. What you approve is what appears on the invoice.

San Marcos customer feedback
★★★★★
Called on a Saturday morning about no heat. They were honest that they could not get out until afternoon, gave me a window, and hit it. I appreciate not being strung along.Erica J. · San Marcos, TX
★★★★★
Whole house was cooling unevenly. Instead of selling me equipment, they measured static pressure and found the return was way undersized. Fixed the return, added a duct run, problem solved.Steve K. · San Marcos, TX

Questions
Emergency 24 Hour HVAC Repair FAQs — San Marcos, TX
Do you really answer the phone at 3am?
Yes. The San Marcos emergency line at (833) 435-6611 is answered by a live dispatcher around the clock, every day of the year. You will get a realistic arrival estimate rather than a promise nobody intends to keep.
What counts as an HVAC emergency?
No cooling during extreme heat, no heat during a freeze, water leaking into ceilings, burning or gas smells, sparking equipment, and breakers tripping repeatedly. Anyone in the home with a medical vulnerability moves the call up the list.
How much more does after-hours service cost?
There is an after-hours rate and you are told the exact amount before dispatching a technician. Once on site, the repair itself is quoted flat-rate and approved by you before work begins.
Should I shut my system off while I wait?
If it is icing, smoking, smelling of gas, leaking water into the structure, or tripping the breaker, shut it off at the breaker and leave it off. If it is simply not cooling well, you can leave the fan running to keep air moving.
Can you get parts at night?
Our after-hours trucks carry the same stocked inventory as the day crew, which covers most emergency failures. If a specialty part is required, we stabilize the situation and return as soon as supply houses open.
Do you handle emergency heating calls too?
Yes. 24 hour heating repair in San Marcos runs on the same dispatch line. No-heat calls during freezing weather are prioritized the same way no-cooling calls are during a heat wave.
How often should HVAC equipment be serviced in Texas?
Twice a year is the standard: cooling in spring, heating in fall. Texas systems run far more hours than equipment in cooler states, so annual-only service tends to let small problems mature into breakdowns. Details are on our San Marcos AC tune-up page.
What size air conditioner does my San Marcos home need?
Size is determined by a load calculation, not square footage alone. Insulation, window area and orientation, ceiling height, duct condition, and shading all change the answer. We run that calculation as part of every replacement quote, because an oversized unit short cycles and leaves the house humid.
