A/C and Furnace Maintenance

To save money on costly repairs and to extend the life of your equipment, schedule regular maintenance on your units. Manufacturers recommend having maintenance done twice per year to help your systems continue to run smoothly and efficiently throughout the year. Maintenance is typically performed once in the spring and once in the fall. During spring maintenance, the technician will perform maintenance, inspect, and test run the air conditioner to make sure the unit will cool your house effectively throughout the hot San Antonio summers.  During fall maintenance, the technician will inspect and perform maintenance on the furnace and will also assess the wear and tear of your unit. Proper preventative maintenance can save time, money, and heartache in the long run and will give you ample time to repair any issues or replace any parts before being faced with unpredictable or extreme weather conditions.

For newly installed units, it is also important to schedule proper preventative maintenance so that in the case of a claim, the equipment will be covered by the manufacture’s warranty. Most manufacturers require for the equipment to be inspected and maintained twice per year and may request proof of proper preventative maintenance in the event that a claim needs to be submitted.
