When your air conditioner fails on a scorching San Antonio day, you need fast, effective solutions. Our AC repair service is designed to restore your cooling comfort quickly and reliably.

We perform thorough inspections to identify the root cause of your problem, whether it's a refrigerant leak, a frozen coil, a faulty compressor, or a malfunctioning fan.

For first-time customers, we even offer a special $29 service call when you mention seeing it on our website.

This service is essential for any homeowner or business owner experiencing weak airflow, strange noises, warm air blowing, or a system that won't turn on. Delaying repairs can lead to more extensive damage and higher costs. With our 24/7 emergency service guarantee, you never have to suffer through a hot night.

Trust the highly-rated experts at ASC Heating & Air for dependable AC repair that gets the job done right the first time.

Investing in a new heating or cooling system is a significant decision for your San Antonio home or business. Our professional installation service ensures your new unit operates at peak efficiency, reliability, and comfort for years to come. We guide you through the entire process, from selecting the perfect system to the final precision installation.

Our certified technicians are experts in all types of systems and are certified dealers for top brands like Trane and York. We help you choose the right size and model based on your space, energy efficiency goals, and budget. A proper installation is critical; an incorrectly sized or poorly installed unit can lead to frequent breakdowns, uneven temperatures, and skyrocketing energy bills.

We understand the financial consideration, which is why we offer flexible financing options, from great credit to credit-in-repair programs. Furthermore, we stand behind our installations with strong warranties, including a unique satisfaction guarantee: if your new unit doesn't work to your satisfaction in the first year, you get a free replacement. Choose ASC Heating & Air for an installation done right, backed by expertise and unwavering support.
