Home Air Conditioner Tips

If you are looking for home air conditioner tips or summer heat management, you have come to the right place. We just compiled all the knowledge to keep your cool this summer. We are explaining everything in detail. If you’d like just a quick browsing, look for the subtitles and tips. Tip: Your working a little more on the A/C will make the A/C work a lot less to provide you the cool. Remember the A/C charges on the electrical bill by the minutes it works.

How AC Works:

An air conditioner has an indoor coil to cool the air and an outdoor coil to dump the heat. Freon circulates between the two coils. The driving pressure of the Freon comes from the compressor. Freon evaporates inside the indoor coil and condenses inside the outdoor coil. Tip: Freon can escape because it is vapor under pressure. Leaking of Freon will reduce the cool and cost more money to run the A/C.

Heat Transfer:

Freon brings heat from the indoor coil to the outdoor coil in the form of latent heat. The coils need to pass the heat from indoor air to outdoor air. Air is thousands times lower in heat transfer capacity than the evaporating or condensing Freon 2匹窗口冷氣機. Manufacturers put fins on the coils to increase contact with air and use fans to drive more air through the coils. Still, the air side is the bottle neck. Any dirt on the coil surfaces or blockage of air flow will make it worse. Tip: Think of heat. The easier we let the A/C to pass it, the less we need to subject to it.

Taking Precautions for Safety:

Avoid damaging any tubing or wiring. Use goggles and gloves. Keep parts and screws in clean places. Make sure you can put the pieces back as they were. If you do not feel comfortable or not sure about a process, do not attempt it. Annual A/C tune-ups are recommended by the U.S. Department of Energy. Many local companies offer such services. Check to see if it is better for them to do it. Tip: Check your air conditioner manual to see what maintenance is needed and how to do it.

Clean the Airways:

The coils need good air flow to pass heat. If plants and shrubs have grown around your outdoor unit. Cut them down. If leaves and debris have gotten in the unit clean them out. If you have things placed near the AC, move them away.

Clean the AC off Dust:

Dust on the coil surfaces will reduce heat transfer. Dust on the fan blades will slow down the fan. Open the lid or the cover to check inside the A/C. Vacuum or blow any dust off the coil surfaces. Clean dust of fan blades will save money as well. Check to see if any activities of spiders or ants near the bottom of the outdoor unit.

Clean Or Replace the Filter:

Look the front of the coils for the filter(s). Take the air filter out and clean it. If the filter looks dirty and clogged after shaking off the dust, it is a good idea to replace it. Dirty air filter can actually suffocate your air conditioner. Your A/C has to run longer time to make up the cooling. Tip: Clogged filter may cost more on electrical bill than the price of a filter each year.

Common Sense Checking:

Always pay attention to unusual noises. Are the fans and the compressor humming like they used to? Do you feel the cool air coming too late and too little? Follow all metal surfaces and pipelines to see if any insulation is broken. If there is any rust. Some rust outside a thick part may not be a big problem. You may slow down the rust with rust-inhabit paint if necessary. Reducing moisture around the parts will slow down the rust. Tip: You’ll find more rust on the shadow side than the sunny side of a pipe.

Freon Leakage and Recharge:

Freon will manage to diffuse over time or rush out if it finds a leak. You may check if there is a problem with Freon like shown in this video. You need the A/C to run more than 30 min to do this. A hot and humid day is a better time to check. Basically you find a metal surface of the insulated line and feel if it is cold. If you do not get cooling and the line is not cold, the A/C is out of Freon. Before refill, make sure if there is a leak you need to fix. Tip: A sudden loss of cooling will not be fixed by just filling the Freon.

Replacement Cost:

Here is a Federal Tax Credits for Consumer Energy Efficiency. There is a good calculator to give you a ballpark comparison to a newer system. You may end up with more costs than this simple calculation. Tip: If you can keep your family cool this summer and replacement is beneficial, do it later in a cooler season may cost less.

Help Your Air Conditioner to Help You:

If you have a door or window open, the A/C has to cool down all the hot air that come to the house. Try to minimize air leak into or out of the house. If you installed the A/C on a window, make sure it is sealed well in the window opening. Check if your outdoor unit on a hot spot. Tip: Creating some shade but not blocking air flow for the outdoor unit will lower the air temperature and save money.
