PREVENTATIVE
MAINTENANCE

ONE OF THE BEST WAYS TO ENSURE YOUR HVAC EQUIPMENT REMAINS FUNCTIONING FOR AS LONG AS POSSIBLE IS BY KEEPING UP WITH PREVENTATIVE MAINTENANCE. ROUTINE MAINTENANCE WILL HELP PREVENT DAMAGE TO YOUR HVAC SYSTEM AND MINIMIZE THE COSTS OF ANY NECESSARY REPAIRS. HVAC EQUIPMENT CONTAINS MULTIPLE COMPONENTS AND MOVING PARTS THAT CAN AND DO FAIL. WHEN COMPROMISED, ANY OF THESE COMPONENTS CAN RENDER THE EQUIPMENT INOPERABLE - AND SOMETIMES IRREPARABLE IF LEFT FOR TOO LONG. PREVENTATIVE MAINTENANCE SERVICES ALLOW US TO CATCH PROBLEMS BEFORE THEY CAUSE CATASTROPHIC DAMAGE, UNEXPECTEDLY LEAVING YOU WITHOUT HEAT/COOL AIR WHEN YOU NEED IT MOST.

PREVENTATIVE MAINTENANCE FAQ

WHEN IS THE BEST TIME TO SCHEDULE A PREVENTATIVE MAINTENANCE SERVICE?

MANUFACTURERS RECOMMEND HAVING YOUR HVAC EQUIPMENT INSPECTED AND MAINTAINED BY A TRAINED LICENSED TECHNICIAN AT LEAST ONCE A YEAR. FOLLOWING THIS RECOMMENDATION WILL ENSURE THE MANUFACTURER WARRANTY REMAINS VALID ON YOUR EQUIPMENT.

SOME HOMEOWNERS CHOOSE TO HAVE ALL HVAC EQUIPMENT SERVICED AT THE SAME TIME DURING ONE PREVENTATIVE MAINTENANCE SERVICE. OTHERS PREFER THEIR EQUIPMENT BE SERVICED SEPARATELY, SCHEDULING MAINTENANCE SERVICES BEFORE THE UPCOMING SEASON (HEATING IN THE FALL, COOLING IN THE SPRING). YEO MECHANICAL, LLC IS AVAILABLE FOR ROUTINE MAINTENANCE ANYTIME OF YEAR FOR ALL OF YOUR HVAC EQUIPMENT - BUT KEEP IN MIND THERE MAY BE SOME LIMITATIONS WHEN SERVICING AN OUTDOOR UNIT IN THE WINTER.
