We went through a record-setting heat wave just recently in the US. Here in Atlanta, we set an all-time record of 106 F. Homes with properly-sized air conditioning unit are sized for a temperature level of 92 ° F and probably didn't stay so cool. I make sure numerous homes with air conditioning system that seem considerably extra-large didn't remain cool enough either.
Every summer you can discover lots and great deals of suggestions on how to save energy and keep one's cool in your home: Use cooler clothing, utilize your ceiling fans, keep the sun out, go to a motion picture, get your air conditioner serviced, caulk your windows, and so on. I will mention a couple of common pointers in this post, but I'm likewise going to go over some that you might never ever have actually seen in a short article like this prior to.
Prior to we enter into the actual tips, though, it might be handy to bear in mind how the entire cooling thing works. Earlier this year, I heard a terrific expression on the radio: Your a/c unit is the faucet; the structure envelope of your house is the cup. If you have a leaking cup, your a/c unit has to work more difficult. If your AC is currently doing all it can, you may require to have a look at your structure envelope. Also, to return to the metaphor, a leakage in your pipes might make it difficult to fill the cup, even it's not dripping much.
Here are three concerns to ask as you try to keep cool with an air conditioner that has a hard time on those truly hot days:
- What can I do to reduce the quantity of heat getting in?
- What can I do to make my a/c unit more effective?
- What else can I do to keep cool?
Let's dive into the tips now. I'm focusing here on existing houses. Whether it's a brand new home you simply moved into or a a century old, the house is already there, so some design choices are off the table.
Tips for keeping heat out
1. Keep the sun out. Windows can be the largest contributors to your heat gain. When the sun shines straight into the home, it usually brings a lot of heat, too, unless you have truly great windows (with low solar heat gain coefficients). Solar screens on the exterior of the window are excellent for keeping heat out. You may likewise consider some short-term shading for the east- and west-facing windows on those incredibly hot days.
2. Seal the strange air leakages. The majority of the standard energy-saving recommendations tells you to caulk your windows and weatherstrip your doors. The issue with that is you're disregarding a few of the much bigger leakages, like, say, crawl space vents that open into conditioned space or a hole in the cooking area ceiling that functions as a refrigerator vent. Browse in your attic, crawl area, or basement, and you'll find the worst culprits.
3. Decrease the surface temperature levels. Some parts of your house might be hotter than others. For instance, you may have a bonus room that's hardly ever comfy. Attic kneewalls with ineffective insulation are frequently the culprit there. Get the insulation in the cavities and put sheathing on the attic side of the kneewalls.
Tips for assisting your a/c unit
4. Change your filter. The majority of people let them get too dirty, and this is among the most typical reasons for poor performance in ac system. An unclean filter includes resistance and lowers air flow. Go on and check it now. I'll wait till you return.
5. Improve air flow. In addition to the air filter, your AC may have other types of air flow issues. If the evaporator coil is dirty, insufficient air moves across it and your house doesn't cool off in addition to it should. If the condenser coil is unclean, it won't dump sufficient heat to the outside. If your condenser coil is crowded with plant life or other challenges, clear it out. You can trim the bushes yourself, but you should most likely call a pro to clean the coils.
6. Search for detached ducts. If your ducts are outside of the conditioned area in your house, check to see if anything has come loose. Fixing a supply duct that's sending out all its cool air to the attic or crawl space (as shown below) can have an instant impact on your comfort. This problem is more typical than you may believe.
Other suggestions for keeping one's cool
7. Use fans. OK, I know this one's not unusual, however if your ac system is doing all it can however your house still isn't rather cool enough on those really hot days, moving the air over your skin might be just what you require to remain comfy. Keep in mind, though, that fans do not cool the air; they cool you. Switch off ones that remain in empty rooms due to the fact that they're utilizing energy and including more heat to your home. Need to purchase a new ceiling fan? They now feature energy performance labels showing how energy effective they are.
8. Utilize a window a/c unit. If you've done everything above and your home is still uncomfortably hot, setting up a window system Air Conditioning could give you just enough extra cooling to help you make it through the heat wave. I know. I know. They're unsightly and noisy and might be against the rules where you live. They utilize more power, which adds to the pressure on the electrical power grid, and might contribute more to global warming. Still, if you have actually got an energy effective house with a right-sized a/c, this could be the finest way to deal with those heat waves when temperatures work out above what your central air conditioning conditioner was developed for. It's a better service than setting up an extra-large system just so you have enough capacity to manage the severe heat occasions. A more expensive and long-term option to the window unit would be a ductless mini-split heat pump.
9. Get a home energy evaluation. Trained home energy auditors can find the issues I listed above and more and advise services. They likewise have equipment to measure how dripping your ducts are, for example, as well as the surface temperatures of your floors, walls, and ceilings.
10. Switch off your power attic ventilators. If you have power attic ventilators in the attic, have them disconnected so they do not run. They might well be robbing cool air from your house.
If your air conditioning unit repair company recommends replacing your system with a bigger one to deal with heat waves, be wary. Air conditioners don't dehumidify well if they do not have long term times, and keep in mind that heat waves do not last permanently and we do not have bad ones every year. If your Air Conditioner can't maintain when it's hotter than regular air conditioner toronto outside, utilize the advice above to make it through. Your house will be more comfortable and effective for it even when the temperature levels go back to regular.
