Alright, we know you didn't major in Heating and Cooling. It's okay. We've got a crash course for you. Here's the 101 on everything you need to know about Heating and Cooling systems.Mark Your CalendarAll of your Heating and Cooling systems need a checkup once a year. Heaters should be maintained in the fall because of how hard they work in the winter. As far as your air conditioner is concerned, have an HVAC professional take a peek at it in the spring. That way you'll be able to crank up the A/C when it gets hot enough to fry an egg on the sidewalk.Try This At HomeDon't feel like calling a professional? Lucky for you, some Heating and Cooling maintenance can be done right at home. By you! Yes. You. Homeowners can perform simple heater and air conditioner maintenance jobs to increase their systems' efficiency. Try these quick fixes to save yourself some cash and a phone call:Air ConditioningClean or replace the air conditioner filters once a month. And while you're at it, take a peek at the exterior air compressor (the noisy thing on the side of the house with the huge fan on it). Don't worry. All you have to do is make sure the compressor's airflow isn't blocked. You'll know that there's limited airflow if there's an obstruction or if the compressor is clogged. Okay, so, there's something holding up the air? No need to stress. Clearing the compressor is as simple as washing it with hose water. That was easy.HeatingFurnace filters are a little less high maintenance than those for air conditioning and only need to be replaced once a year. Gas furnaces are easy to monitor at home. Make sure the pilot light burns blue. If it's yellow or orange, give your Local Heating and Cooling Pros a call. But, when it comes to heating, it's best to leave the other details to the pros. Combining electricity with natural gas or oil can get a little tricky.Leave It To The ProsSafety? Check!A Heating and Cooling pro should ALWAYS perform a safety check before starting maintenance. So, what's really going on in there? While holding a flashlight and squinting his or her eyes, your professional ensures that all moving parts are well-lubricated, checks thermostat settings for accuracy, tightens electrical connections and ensures that they aren't sparking up a storm in there.The serviceperson also inspects the heating and cooling systems' condensate drains. It's their job to make sure that they're no clogging. Keeping these drains from getting plugged prevents water damage. Hooray! No mold for you!Then there's some air conditioner clean-up to do. Your service professional's safety check also includes cleaning the condenser and evaporator coils. Dirty coils make for a less efficient air conditioner. Said "dirty coils" can cause your air conditioner to take TWICE as long to get to the same temperature as a unit with clean coils...leaving your pockets twice as empty.Heater maintenance is all about fire prevention. Safety checks of a heater include checking the gas pressure, burner combustion, heat exchanger, and gas connections. Slacking in any of these areas increases the risk for fires.Duct, Duct, GooseDuctwork cleaning is another thing to leave in the capable hands of your local Heating and Cooling pro.
