Ten Unusual Pointers for Keeping Your Home Cool with a Struggling A/C


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. House with properly-sized air conditioning unit are sized for a temperature level of 92 ° F and most likely didn't stay so cool. I make sure several houses with a/c unit that appear to be substantially oversized didn't stay 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 the house: Use cooler clothing, use your ceiling fans, keep the sun out, go to a motion picture, get your air conditioning system serviced, caulk your windows, and so on. I will mention a few common tips in this post, but I'm likewise going to discuss some that you might never have seen in an article like this prior to.

Prior to we enter into the real ideas, though, it might be helpful to bear in mind how the entire cooling thing works. Previously this year, I heard a terrific expression on the radio: Your air conditioning unit is the faucet; the building envelope of your house is the cup. If you have a leaky cup, your air conditioner needs to work more difficult. If your AC is already doing all it can, you might need to have a look at your building envelope. Likewise, to go back to the metaphor, a leak in your water pipe might make it difficult to fill up the cup, even it's not leaking much.

Here are three concerns to ask as you attempt to keep one's cool with an a/c that has a hard time on those really hot days:

- What can I do to decrease the quantity of heat getting in?

- What can I do to make my air conditioning unit more efficient?

- What else can I do to keep one's cool?

Let's dive into the suggestions now. I'm focusing here on existing homes. Whether it's a brand name new house you just moved into or a a century old, the home is already there, so some style choices are off the table.

Tips for keeping heat out

1. Keep the sun out. Windows can be the largest factors to your heat gain. When the sun shines straight into your house, it normally brings a lot of heat, too, unless you have actually excellent windows (with low solar heat gain coefficients). Solar screens on the exterior of the window are great for keeping heat out. You may also consider some momentary shading for the east- and west-facing windows on those very hot days.

2. Seal the unusual air leaks. Most of the basic energy-saving guidance tells you to caulk your windows and weatherstrip your doors. The problem with that is you're neglecting a few of the much bigger leakages, like, state, crawl area vents that open into conditioned space or a hole in the kitchen ceiling that serves as a refrigerator vent. Take a look around in your attic, crawl space, or basement, and you'll find the worst culprits.

3. Decrease the surface area temperature levels. Some parts of your home may be hotter than others. For instance, you may have a benefit room that's rarely comfy. Attic kneewalls with inadequate 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 ac system

4. Modification your filter. Most people let them get too unclean, and this is one of the most common factors for poor efficiency in air conditioning system. An unclean filter adds resistance and minimizes air circulation. Go on and check it now. I'll wait till you get back.

5. Enhance air flow. In addition to the air filter, your A/C might have other kinds of air circulation problems. If the evaporator coil is unclean, not enough air relocations throughout it and your home does not cool off as well as it should. If the condenser coil is unclean, it won't discard enough heat to the outside. If your condenser coil is crowded with vegetation or other challenges, clear it out. You can cut the bushes yourself, but you must most likely call a pro to clean up the coils.

6. Try to find disconnected ducts. If your ducts are beyond the conditioned area in your home, check to see if anything has actually come loose. Repairing a supply duct that's sending out all its cool air to the attic or crawl space (as revealed listed below) can have an immediate impact on your comfort. This problem is more typical than you might think.

Other pointers for keeping one's cool

7. Use fans. OK, I understand this one's not uncommon, however if your a/c unit is doing all it can however your house still isn't quite cool enough on those truly hot days, local hvac contractors moving the air over your skin might be simply what you need to stay comfy. Remember, though, that fans don't cool the air; they cool you. Switch off ones that remain in empty rooms due to the fact that they're using energy and adding more heat to your home. Need to buy a new ceiling fan? They now include energy efficiency labels showing how energy efficient they are.

8. Utilize a window air conditioning system. If you've done whatever above and your house is still annoyingly hot, setting up a window system AC might offer you just enough extra cooling to assist you make it through the heat wave. I understand. I know. They're ugly and loud and may be against the guidelines where you live. They utilize more power, which contributes to the pressure on the electricity grid, and might contribute more to worldwide warming. Still, if you've got an energy efficient home with a right-sized a/c unit, this might be the very best way to handle those heat waves when temperatures go well above what your central air conditioner was created for. It's a far better service than setting up an extra-large system simply so you have enough capacity to handle the severe heat occasions. A more costly and irreversible option to the window unit would be a ductless mini-split heat pump.

9. Get a house energy assessment. Trained house energy auditors can find the issues I listed above and more and suggest services. They likewise have equipment to measure how dripping your ducts are, for instance, in addition to the surface area 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 detached so they don't run. They might well be robbing cool air from your home.

If your a/c unit repair company recommends changing your system with a bigger one to deal with heat waves, beware. Air conditioning system do not dehumidify well if they do not have long run times, and bear in mind that heat waves do not last permanently and we don't have bad ones every year. If your AC can't keep up when it's hotter than typical outdoors, use the guidance above to make it through. Your house will be more comfy and effective for it even when the temperatures return to typical.
