AC & Heating Maintenance & Tune-ups in San Antonio, TX
Take a proactive approach to caring for your cooling and heating system, and you'll prolong the life of your system and help avoid costly repairs. At ABC Home & Commercial Services, we understand that these systems are complex, and that maintenance can be difficult for you to do on your own. That's why we offer AC and heating proactive maintenance in San Antonio. With the help of our pros, you can get the most out of your system.
ABC’s proactive maintenance plan is called our Advantage Maintenance Plan 500, or AMP500, for short. To get the most lifespan and efficiency out of your system, our AMP 500 entitles you to 2 precision tune-ups each year. One is a ‘cooling-focused’ tune-up, done to help ensure your air conditioning system is fully prepared for the high summer temperatures. The second is a ‘heating-focused’ tune-up, performed to ensure your heating system is working properly before temperatures drop.
Other major advantages of the AMP500 include:
Priority Scheduling
You receive priority status for all service calls. When your home has an issue, you want it to be addressed as soon as possible. Jump in front of all non-AMP customers in the queue for service.
Replacement Credit Advantage*
Each year, half of your annual AMP subscription cost will be credited to a reserve account to be applied toward your next full AC system replacement. ABC will also contribute an additional $500 to your reserve account upon your first AMP renewal. Your reserve credit is even fully transferable if you sell your home!
Discount on Repairs
All AMP customers get 10% off the cost of all AC, Electrical, Plumbing, and Appliance Repair service work (maximum discount of $50.00).
*If you cancel your Advantage Maintenance Program agreement, any accrued AMP replacement reserve credit will be forfeited.
The ABC Process
1. Contact ABC
When you contact us, we will schedule a service call to conduct a diagnostic on your heating and cooling system.
2. Perform Maintenance
We'll go over a checklist of items to make sure all parts of your heating and cooling system are working properly.

We will update you on the work we performed and let you know of any recommended follow-up services.
4. Schedule Next Tune-Up

You can proactively avoid costly repairs and breakdowns with regular preventative maintenance to keep your air conditioning system running at peak performance. Just like your car, serving your AC system regularly helps keep it functioning properly and efficiently. You wouldn’t tell someone not to change the oil in a car, right? Well, think of your AC system in the same way!

“I can honestly say that my service today with Jeremy was exceptional! Jeremy performed the service quickly and professionally and answered all of my silly questions patiently . He also spoke highly of his company, peers and management! He also recommended with no sales pressure a service I might benefit from and as requested, he relayed to his office my interest and a follow up appointment has been scheduled. Bailey scheduled the appointment and she was also very helpful! Thank you ABC for creating a culture that exceeds your customers expectations!”

“ABC has always been top rate: friendly and helpful from scheduling to the techs. I’ve used them for HVAC and they are honest and shoot you straight. These days most of the formerly locally owned shops are bought up by Private Equity and they are just trying to run the rates sky high (while keeping the old name and pretending to be small and local). ABC is still proudly locally owned and operated; they know that good service and honesty will bring them more business in the long run and that’s who I like to work with! I recently worked with Kevin G who was awesome; friendly, kind, informative, and efficient. He also said how much he enjoys working for ABC and how well he is treated; which is another good reason to use them!”
