HVAC stands for heating, ventilation and air conditioning, and there isn’t a residential or commercial building in the nation that doesn’t have some version of HVAC. Without it, we’d be at the whims of Mother Nature all year. At the end of the day, however, the comforts of heating and air conditioning are lesser to the hygienic needs of air circulation HVAC provides. Trust me, if any part of your HVAC system falters, it’s not hard to notice.
Like your neighbors, you should always get to know your HVAC systems. Homeowners know where the thermostat is and can see the vents, but, for most, that’s where their knowledge of HVAC ends. Following the vents will lead you to your heating and cooling systems and knowing how they should be operating will help you prevent malfunctions and identify them. And like most things, some light reading is needed. Central heating/AC systems come with a guidebook and, yeah, I’d rather be reading Elmore Leonard too, but reading it will help you figure out where to find vent entry points and other useful information. In fact, any manufacturer will surely have it available to download via their website. If your unit is outside, you should clear it of any debris as regularly as once a week.
Back inside! In many cases, vent filters need regular upkeep; once a month is totally respectable. Pop open the vent at the entry point and check to see that the filter isn't caked with dust. You should also replace your filters twice a year, once in summer and once in winter. Any home improvement store worth its salt will have filters in stock.
Vent areas where moisture is prevalent can also lead to mold. Scrubbing off the mold with a solution made with equal parts bleach and water will solve that issue and evaporator coils wipe down at 10-15 times a year. After rain or snow, be sure to check for any standing water and tend to it immediately. It’s also important to keep an eye on the fans, as they tend to accumulate dust and grime. Fans should be wiped down bi-weekly, or monthly at the very least. If at all possible, it should become as normal as mowing the lawn.
These are easy ways to avoid problems, but there are some things that just require training and that professional touch. Every two years or so, get a certified HVAC technician to give your entire system the once over and they will give it the real buff and shine, to ensure efficiency and that your warranty gets a thorough use. In these bitter days of winter, heating is crucial and a little cleaning beats icicles on the ceiling.
