Top 4 HVAC Repair Myths

  1. A technician said my coil is rusty therefore I must have a leak. Although likely to be true, it is not 100% accurate. The coil rusts when too much water or ice builds up on the coil over time. Ice can build up on the coil for other reasons, not just for leaks. Air flow has just as much impact on creating a frozen coil situation. Crushed ducts, poor design or dirty air York Air Conditionerfilters can all prevent enough warm air from flowing across the coil to prevent it from freezing. Proper maintenance and routine filter changes can help prevent frozen coils.
  2. My Capacitor is not swollen so it must be good. Not necessarily. A capacitor can be weak but not dead. A weak capacitor can wreak more havoc than a dead capacitor. Usually a dead capacitor will prevent the motor from running. Whereas a weak capacitor will allow the motor to run under poor conditions and quickly shorten the life of the motor. Motor replacements are expensive.
  3. A technician said a UV light would prevent dirt in my ducts. While a UV light helps prevent bacteria from growing on your coil, it does not prevent or destroy dust particles. Those pass the light unaffected and build up on motors and insulation that allows mold growth.
  4. I don’t need to maintain my heating or air conditioning system until it stops working. Although this is the choice most homeowners make, it is incorrect to assume the system will run fine without maintenance. Hidden dangers build up every year that a system goes without maintenance. Capacitors start to go weak (see item #2), compressors start to run hotter, drain lies build up with mildew. Delaying the maintenance will likely force the homeowner to spend more money on major repairs sooner than would be normal for a well maintained system. Maintenance does not guaranty your system will not need any repairs, but it does improve the life span of one of the most expensive systems in your home. You change the oil in your car every 3000 miles, why wouldn’t you have your system cleaned and inspected every year too.

How often should I change my Air Filters?

When they are dirty or every 3 months which ever comes first.

I see so many homes with clogged air filters when I arrive. This can wreck havoc on your air conditioner and heater as well as your indoor air quality. Dirty filters can lead to frozen pipes, dirty blower fans, and burned out blower fan motors. Dirty Filters

Risking a $700 fan motor replacement bill over a $6 filter is ridiculous. Buy a box of filters from your local supply store and keep them in your closet. Then change those filters when they look gray or every 3 months. save yourself some agony and money.

Pets and kids will clog your filter faster than a home without pets and kids? Think about it, pets have twice as many legs and move them twice as fast as an adult human. Therefore they will kick up more dust and other airborne particles much easier than otherwise. The airborne particles collect on your filters and halt the air flow to your air conditioner or furnace. This causes the fan motor to work harder and possibly shorten the life of the fan motor.

Do not pay attention to the filter life displayed on the filter packaging. Unless the filter is thicker, such as a 2″ thick filter, most filters only last around a month in the average household. Even if the filter says a 3 month filter, it just means it is a more dense filter that collects more airborne particles. And as was just pointed out, the more airborne particles collected, the more frequent you will need to replace the filter to prevent the loss of air flow.
