Read this article to learn more.

Make a circuit around your home before calling for help with your HVAC. Make a list of the temperatures in each room and whether they are hot or cold. The contractor can probably figure out and fix the problem easier.

When your contractor comes to fix your unit or install a new one, he should walk around your home and investigate what's going on with your current set-up. They should be looking for how much insulation you have, where your windows are and what quality they are and more.

Know what you need before you hire a contractor. Providing you with an accurate estimate over the telephone may be difficult to impossible is they can't see the system you have. It will be even harder if you cannot explain what you have done. Understand this information beforehand.

You want to put the outdoor compressor device in a shaded area. In this way, it will be cooling air that is already somewhat cooled. This saves energy.

Have your HVAC serviced at least yearly. It's best to have it checked before you turn it on for the summer and again for the winter. Even if everything seems fine, check things out to find potential problems.

Before you hire any HVAC company, ask them how long they've been open for business. The older they are, the more likely it will be for you to find out their history, which will help you gauge their quality. If you hire someone that's new that this then you'll be risking your money.


If your evaporator coil, found inside your home, becomes dirty, your unit will lose efficiency. Just pop off the front panel of the furnace and check to see that the coil is dry. Using a brush attachment on a vacuum, gently clean the coil of any dust or other debris.

Always take the time to check out the reputation of any HVAC contractor before you consider hiring them. Check reputations at the BBB, and read online reviews to gauge customer satisfaction. This is what you have to do in order to make a smart decision.

Be careful of sounds in your HVAC. If the condenser fan begins to make a grating or clicking sound, the blades could be hitting an obstruction. If blades get bent, don't try straightening them. You could unbalance them and cause them to hit the condenser coil. This could loosen the motor in the fan. Try replacing the bent blades with new ones. Make sure the new blades can freely rotate without wobbling.

Before having someone install a new HVAC system or maintain or repair yours, make sure they are insured. Having someone who is insured work on your system will assure that if anything happens while they are working at your home, they are financially covered and you will not be responsible.

Be sure to check your Filter Check light frequently on any stand-alone units. If it is on, turn the unit off as you can't operate it without a filter in place. Clean the filter carefully and return it to its proper location, but don't operate the unit if the filter is still wet.

If you don't know who you should call to repair, install and maintain your HVAC systems, check out reviews online. In many cases you will find local review sites where previous customers will share the experience they had with companies they used. This will tell you who is great and who isn't.

If you are going to use the Internet as a source for good HVAC contractors, you need to be very careful. You never know who is behind the glowing reviews that are posted all over the Web. There is a chance that the contractor is posting their own reviews or paying others to do so.

Think about installing a digital programmable thermostat to keep your heating and cooling bills low. These digital thermostats have timers that allow you to completely control your HVAC use. You can set the heat and cooling to only turn on when you are home and to turn off when you are at work.
