Commercial Air Conditioning Maintenance Program

San Diego Commercial Air Conditioning ServiceIf you are looking for a Commercial Air Conditioning Service, don’t wait until summer when it may take days for a technician to come out and fix your A/C! Let Allegiance come out and inspect your A/C unit prior to the heatwave. Allegiance now offers a Preventative Maintenance Program that could put you on the right track for summer. Heating and cooling systems need to be serviced and maintained annually to ensure the system will function at its best possible use. We will check and adjust the thermostat, freon levels, all coils for cleaning, and belts for wear. We inspect fan motor and blades and lubricate if needed. Inspect the control box, circuit board, relays, contactor, capacitors, etc. and all electrical connections. Inspect the drain pan and clear debris if needed. Replace air filter or clean reusable type filter if needed. Allegiance will check the complete system thoroughly and advise the client if there will be any additional services to ensure the system is in its proper working order for the summer. Annual contracts are offered. People love us on Yelp!
