It’s important to efficiently heat and cool your home. Because of this, you should make sure that your home’s HVAC system is working properly. Maintenance is key. Below, you will find some great tips that range from finding a good contractor to ensuring your unit is working properly.

Be sure to get every quote or estimate in written form. You have no recourse on a verbal agreement, so a written contract is a must. This will allow you to follow up if something goes wrong or you don’t get what you were promised, protecting you from shady contractors.

Clean your permanent air filters or replace disposable ones every single month. If you have the choice, an electrostatic is the best option on the market today. Be sure to turn off your unit before you change the filter as it should never be run without a filter in place.

Clean the condenser on your debris regularly. You don’t know the amount of stuff that can pile up right after heavy winds or a storm. Overheating could occur, which will be problematic.

Your HVAC unit may suffer when trees start to lose their leaves. Make sure you clean out your fan grill often once nearby trees start shedding their leaves. The fan should have a clear path for air to come in. If it is blocked, your system will suffer.

When you are no longer using your outdoor air conditioning unit, be sure to protect it with a tight cover. This will keep it free of debris, frost and snow so that you’ll have a working unit when the spring comes and you are ready to uncover it and use it again.

Whenever possible, try to shade the compressor unit outside. The air that’s in a place that is shaded is usually five to six degrees cooler than the surrounding air. Your air conditioning unit will be up to ten percent more efficient if it is properly shaded during the summer months.

Sometimes, it can be hard to figure out if your HVAC system needs to be fixed or needs to be replaced. If your system frequently breaks down, is always turning on or off on its own, or if your bills are too high, it may pay to have it replaced. Otherwise, little things can just be fixed.

Change your air conditioner filter quarterly, or four times a year. This not only keeps the air coming into your home easier and cleaner to breathe, it takes a lot of stress off of your AC unit itself. You get to enjoy health, money savings and reduced energy use altogether at once.

When you buy a new air conditioning unit, don’t let the salesperson talk you into too large of a unit. This will be a waste of money and won’t efficiently cool your home. The longer a system runs, the more efficient it will be when it’s running, so look for one which runs 15 to 30 minutes.

Now you should be able to see what must be done to keep your HVAC system in working order. Avoid letting it fail by regularly maintaining the system. Use the information above to make sure it’s doing well, so that you don’t get home and find your home is too cold or too hot.
