If you're planning on working with your HVAC system, then it's best to arm yourself with these helpful tips first. This article has some great information for you. Spend a fair amount of time, and you will reap the rewards. Know the name and type of your HVAC system before looking for a repair person.

Clean the coils and blades in your condenser at the beginning of summer. The power to the unit should be removed before you begin any maintenance, even cleaning. Keep the exterior of the condenser unit free of debris. If the fan condenser on your unit has ports for oil, make sure you lubricate it once a year. Most of these ports have some sort of protective cap covering them. Buy an SAE 20 product that isghtweight, and then put no more than ten drops into the ports. Some fan condensers may contain oil parts, and if yours does, ensure it is lubricated at least once per year. You will notice these ports have a rubber or metal cap covering them. Get an oil that is SAE 20 and put about 10 drops into each port, but don't overfill it. Your outdoor HVAC units might suffer when your trees lose leaves. Make sure the fan's grill is cleaned often during the fall. The fan must not have anything in the way so that air can flow into it, and if it is clogged, you'll have a lot of headaches eventually. To increase the efficiency of your HVAC unit, be sure to keep it in the shade. The air in the shade is cooler and can help save on energy costs. Be sure you have the HVAC unit in your home checked about two times every year. The ideal thing to do would be to have it checked out in the fall and spring so you're able to figure out if everything is ready for the cold and hot months. Even if everything seems okay, it doesn't hurt to check things out. If the house is yours or you're permitted to, replace the windows that are single pane with windows that are double pane. Double pane windows will help keep your home cooler in the summer. This same effect also keeps warm air in during the winter months. Don't let your house get too hot. An AC unit will reduce the internal temperature of your home approximately twenty degrees in a fair time. If your home become 100F or more, it will only cool off to about 80F. Depending on how humid the environment is, that is not a healthy temperature for the human body when it rests during sleep. AC units will tend to get ice on them due to the cold. The drainne may also freeze up. If this happens, disable the compressor by switching the thermostat to run the fan only. The fan setting can help melt some of the ice, but you should still call a professional to check your unit out. To help lower cooling costs when not at home, make sure the air conditioner is turned off. You may want to turn your unit off if your house will not become extremely hot or cold. The unit will use a large amount of electricity to combat the heat during the day when the house is empty. You shouldn't rely on a single quote from one contractor to gauge the cost, because different specialists set their own price. Making some phone calls before deciding is a good way to save money. To get the best picture and get an idea of what rates are reasonable, call five or six different contractors. Before you go out there and hire an HVAC contractor, find out the length of time they've been in the industry. The older they are, the morekely it will be for you to find out their history, which will help you gauge their quality. You will be taking a risk if you hire a newer contractor. It's important to have doors and windows that are efficient for the most efficiency for your HVAC unit. Seal them tightly to prevent air from coming in. Have them inspected by a professional. This is often a free service. As you've read, you should care for your HVAC system so that it does not go bad. If you have your HVAC system go bad it can cost you a lot of money to get it fixed. Keep this from happening when you use these helpful tips.
