Scorching days can really feel insufferable with no robust air-conditioning system. But many people take these important units without any consideration. “The one time folks take note of their air conditioner is when it is not working,” says Jeffrey Siegel, a professor of civil engineering on the College of Toronto who researches air flow and indoor air high quality.
That’s a mistake: Taking excellent care of your AC may also help guarantee it gives ample air move, controls humidity, is power environment friendly, and lasts so long as potential. “An air conditioner that is not effectively maintained is not going to present the identical stage of consolation” as one that’s, Siegel says.
Right here’s how consultants recommend tuning-up your AC so it really works optimally.
Change the filter
There’s no common equation that determines precisely how typically you should change your AC filter, which traps airborne particles like mud, pollen, and different pollution. Producers usually advise changing it each three months, and that works as an preliminary goal, Siegel says—however the frequency would possibly have to be tweaked based mostly on your own home atmosphere. Subsequent time you modify yours, examine how soiled it’s. “Once I have a look at my filter, it’s lined with cat hair,” he says. “If I modified it when the producer mentioned to alter it, I might have gone previous the time once I ought to change it.”
There are two huge penalties to not altering your filter typically sufficient, Siegel provides: It reduces air move, which hurts the gadget’s effectivity and skill to offer consolation. Plus, when the filter will get actually soiled, the air begins to seek out paths round it, reasonably than going by means of it—which HVAC consultants name “bypass.” “It will not be treating as a lot air, so there are undoubtedly air-quality issues,” he says.

When AC filters get particularly soiled, allergens, fungal spores, unhealthy smells, and different issues nobody needs to be respiration can flow into again into the home, triggering or exacerbating a spread of lung circumstances, says Dr. Mahmoud Moammar, a pulmonologist with Windfall St. Joseph Hospital in Orange, Calif. “It’s a huge deal, particularly for susceptible folks, like youngsters or aged sufferers with power lung illnesses like bronchial asthma and power bronchitis,” he says. “It will possibly have an effect on their well being tremendously.”
Think about upgrading your filter
Air filters are rated based mostly on the MERV system, which stands for Minimal Effectivity Reporting Worth and measures how effectively they will seize particles from the air. The dimensions goes from 1 to twenty; the upper the quantity, the extra environment friendly its filtration. Decrease effectivity filters are cheaper and don’t should be modified as typically since they’re not eradicating as a lot junk from the air, Siegel says. Typically, although, he prefers utilizing a filter that’s at the least a MERV 13, which helps guarantee good, wholesome air high quality.
Clear up across the outside unit
Earlier than you crank your AC up for the summer season, make sure that to do some upkeep to the realm surrounding the outside unit. Which means eradicating weeds, shrubs, sticks, garden furnishings, and the rest that may have piled up over the winter, says Richie Drew, vp of operations at One Hour Heating & Air Conditioning in Myrtle Seashore, S.C. “You want sufficient area—a pair toes across the unit—for it to breathe correctly,” he says. “If the bushes are proper up in opposition to it, it could possibly’t do what it must do.”

Verify the bottom of the unit, too: Filth can settle beneath, making the whole factor uneven, resulting in efficiency points and main repairs down the highway, Drew says. Use a hose with average water strain (not an influence washer) to spray the entire thing down, clearing away cobwebs or different detritus that may have gathered. “Something obstructing airflow will trigger your unit to work tougher,” he says.
Take the duvet off
Most AC models can stand up to every kind of harsh climate, so utilizing a canopy through the low season isn’t needed. But some folks nonetheless select to cowl theirs up. In the event you’re one in all them, don’t overlook to take away it. “If there’s one factor it’s best to be sure you do each season earlier than you begin operating your air conditioner, it is that when you put a canopy over that unit within the winter, bear in mind you probably did,” says William Bahnfleth, a professor of architectural engineering and an indoor air high quality professional at Penn State College. In any other case, with out correct air move, the unit will not be capable to correctly operate, which might result in overheating and a slew of different issues, together with trapped moisture.
Clear or change clogged condensate drains
Condensate drains are necessary as a result of they take away additional moisture produced through the cooling course of. “Condensation is a pure byproduct of how an air conditioner features,” explains Robert Weitz, founding father of RTK Environmental Group, an unbiased firm that checks indoor air high quality. “It takes heat air after which creates chilly air out of it, so you are going to have a traditional quantity of condensation, which is simply water droplets.” These beads of water should go someplace, so that they exit by means of a condensate drain.

To examine your AC, search for the drain line that runs from the indoor unit to the outside unit. In the event you discover a number of water dripping out of or pooling across the unit, or if the condensation pan is full, you may need a clog. Some folks can repair the issue themselves through the use of a moist/dry vacuum, along with different steps; if that sounds daunting, your greatest guess could be enlisting an HVAC skilled, Weitz advises.
Rethink your utilization habits
A lot of folks run their AC models greater than is definitely needed. “The easiest way to avoid wasting power is to show one thing off,” Bahnfleth says. Plus, the much less you employ your AC, the longer it is going to final. He’s gotten within the behavior of opening his home windows when he will get up at 6 a.m. and letting the surface air hold the home comfy for so long as potential. “I feel we might all be studying use our methods successfully,” he says. “It’s shocking what number of days the cooling by no means must be turned on, and that is going to provide you higher air high quality, too.”
Think about calling in an expert
One of the vital necessary issues to do firstly of AC season is repair something that’s mistaken together with your unit, Bahnfleth says. In some circumstances, that will likely be apparent: You’ll get aggravated by bizarre or loud noises and odors, discover your power invoice has skyrocketed, or spot indicators of a leak. And, in fact, “you’ll in all probability discover that it’s simply too heat or humid,” he says.
Even when your AC doesn’t outwardly seem damaged, it may be value having an HVAC contractor have a look. Most consultants advocate scheduling an annual inspection: These technicians are skilled to search for issues and assist guarantee your unit is working as effectively as potential. “In the event that they’re good, they’re going to do just a few issues,” Siegel says. For instance, they’ll clear off the surface a part of the unit, if you have not already completed so; examine all of the elements inside for general cleanliness; and gauge airflow.
Common upkeep is essential to making sure you’re capable of keep cool when you should, Bahnfleth says. “Annually to have your entire system checked out is a reasonably good place to begin, as a result of lots of people simply do not do any upkeep,” he says. “That’s actually the largest drawback. It’s not that methods aren’t designed effectively—but when they’re not maintained, they will not do what they’re imagined to do.”
