You must make certain that your HVAC unit is well maintained if you want it to work well. A lot of homeowners spend money fixing them up when broken, but could have avoided such issues if they had maintained them properly. The article below will teach you about HVAC systems, and give you great tips on keeping it running great so you never run into these costly problems.

By the end of spring, the fan blades and coils of your condenser should be thoroughly cleaned, so operation can proceed with greater efficiency. Except when cleaning the outside, turn the unit off when performing any type of maintenance. Remove leaves and debris from the outside condenser.

Be careful when doing yard work that you do not get debris on or in your unit. Try shooting the clippings away from it. This applies when you are taking care of the leaves in the yard.

Have the HVAC system checked twice a year at the least. The spring and autumn times are the best time to have it checked. Regular inspection will help you avoid unexpected repairs.

Turn off any outdoor condensers you have when the weather gets cold. This should be done when the temperature drops below 60ºF to avoid damage. This helps your system remain in good working order.

If you can, use double-paned windows instead of single-paned ones. Having double pane windows allows your air conditioning unit to be run much less during the summer, because the cool air is kept inside the home. Likewise, in the winter more hot air stays inside during the cold season.

To cut energy costs, you should service your cooling and heating system once a year at least. When they visit to service the unit they're going to inspect the motors, oil the parts that move, and see how much freon is in your system. This will help keep your system performing at maximum efficiency.

Keep your air conditioner off when people aren't home to save you money. You may want to turn your unit off if your house will not become extremely hot or cold. Leaving it on for the entire day means that it is struggling to keep things cool, something that takes lots of energy.

Don't allow your home to become dangerously hot. Even the best air conditioners can only realistically cool your home approximately 20 degrees Farenheit. This limits their overall benefit. This can still be way too warm for you.

To know how large of an air conditioner you need, look for a calculator online. If you purchase a unit that's too large, it will not be efficient since it'll cool the same. Check the manufacturer's handbook to see what amount of space the unit can effectively cool.

Try to get as many quotes from contractors that you can. You can save quite a bit of money when you call different companies for price quotes. You want to call at least a handful of contractors to determine what reasonable rates are.

Do you wish to buy a new cooling and heating system? Many things must be taken into account before you purchase one. The systems are generally rated based on the area they cover. It is always better to buy a unit that is a little bit bigger rather than one that might be slightly smaller.

If you are a having trouble with your existing system, check for leaks in the ducts. Call local utility companies to test it for you since many do it for a small fee or even free, which is lower than HVAC contractors. When you repair the leaks, the tests will pay for themselves.

Make your HVAC work efficiently when you consider what way your home faces. Block the sun in the morning with trees around your home. Anything that provides shade from direct sunlight can reduce the temperature inside your home and help reduce your energy bill for air conditioning during warm months.

To run your HVAC at full efficiency, you must have efficient doors and windows in place as well. They should be able to seal tightly without letting air seep in or out. A good professional can test this for you, and they might even do it for free.

If you are purchasing an AC unit, take measurements. You need to know how big the area is that you want to have cooled off. Generally, 20 BTU per square foot is ideal. Make certain that you calculate using all of the rooms the unit will be treating.

Before you decide on the location of your air conditioning unit, take a look at the air flow direction. If you have no choice but to put it in the corner, be sure to buy a unit which allows for the air flow direction to be changed away from the wall.

When you hire a contractor, make sure you ask for some references. You need to have the ability to speak with homeowners to see if the services they got were any good and if they cost a lot of money. This will help you stay away from scam artists, but only if you call those references!

Be sure you know what goes into what you're about to pay for the HVAC work if you're paying a contractor. There are contractors out there that will make you pay for extra things like charges for fuel or materials. You can avoid these issues if you have a contract that is written out.

Always look through the references that any HVAC contractor provides you with. A lot of people think that they're legitimate just because they were given to them, but that isn't always true. It will just take minutes to check out a contractor, so you shouldn't hesitate.

As this article has said before, your HVAC system is something that really is important, and you have to be sure you keep it working well. Thankfully, the advice you went over here will help you save yourself from making repairs that cost a lot. Remember that not following them could end up costing you thousands of dollars.
