resourcesas an “end user”, there are several actions you can take to help prevent some of the most common system failures that can occur.1st: ensure that you change or clean your air filters at least once a month for residential users. consult with your hvac professional for recommendations on commercial applications as those needs vary from site to site due to traffic flow and internal activities. 2nd: change the batteries in your thermostat. electronic thermostats have become very popular in the past few years due to their ability to help reduce energy usage. most of these thermostats are internally powered by batteries ( either “aa” or “aaa” ) and require that hese batteries be changed out once a year for proper operation. 3rd: keep plants and debris away from your outdoor unit. leaves and trash can be blown into the coils and clog your system. this has two effects; first it reduces the air flow across your coil resulting in higher energy bill and lower system capacity. second, excess stress placed on your system, while in operation, significantly increases the wear and tear on it reducing its useful life span. 4th: just as your automobile requires periodic check-ups or tune-ups, so does your hvac system. have your equipment checked and serviced by qualified, licensed personnel at least once a year for cooling or heating only equipment and twice a year for combination cooling and heating equipment. this is required by many equipment manufacturers to keep warranties in force. 5th: if you are considering major modifications to your home or office such as moving, eliminating or adding walls, windows or doors, have an hvac professional who is properly trained in evaluating air distribution and heat load characteristics review your plans before you make any changes. they can provide valuable information that can help you prevent building “heat islands” (or dead zones) in to your structure. remember: “an ounce of prevention is worth a pound of cure” |
