Maintenance
Benefits of Scheduled Maintenance
- $$ Reduces energy bills
- $$ Reduces repair bills
- Prevents untimely breakdowns
- Assures safe equipment operation
- Defers replacement costs by prolonging equipment life
Many problems are identified during routine maintenance that are quick and inexpensive to eliminate, and save hundreds of dollars in operating and repair costs. For instance, a faulty compressor capacitor will cause your unit to use up to 30% more electricity and compressor overheating. Unchecked, this results in higher utility bills and possible compressor failure. The cost of operating your unit in this condition for two months would exceed the cost of the repair!
Do I Need My System Checked Every Year?
In San Antonio, central air conditioner units run approximately 2,000 hours per year to cool our homes. If you were to drive your automobile for 2,000 hours in one year at today's speed limit, you would have driven 140,000 miles. You wouldn't think of leaving on a journey like that without making sure everything was tiptop and gas mileage was at its best. It's pretty incredible that our air conditioners can give us up to 25 years of service under conditions like that, when properly maintained.
Maintenance Agreements
Maintenance agreements are designed to extend the service life of air conditioning and heating equipment, and keep them running safely and efficiently. A typical service agreement should provide for a minimum of 2 visits per year (Spring and Fall) by a qualified technician who uses a routine check list to track the performance of your system. Discounts on repairs and emergency service are often extended to maintenance agreement customers. Our preferred customer agreement offers both a generous discount, and an accounting of your system's past performance.
