Needing service on an HVAC system during cold or hot days is a serious frustration. Learning what you can about HVAC units will help you fix them or maintain them. Read on to do that.

Before choosing an HVAC contractor, think of what you wish to have done. They won’t be able to offer you a quote if they haven’t seen your system. They need to come look at the unit. Thus, it is worthwhile to have this knowledge ahead of time.

If your condenser comes with oil ports, you should lubricate it yearly. The port usually has either a rubber or metal cap on top of it. Look for an oil that is lightweight and then put about 10 drops inside the port. You don’t want to put in too much.

Outdoor condenser units need to be turned off when the weather turns cold. If it’s less than 60 degrees outside, turn the unit off. You’ll pay less for repairs which you follow this tip.

A good way to save money with your air conditioning is by installing a programmable thermostat. You have greater control over the temperature settings with these. Some of these thermostats can even be controlled from your smart phone or computer.

Service your hearing and cooling systems once each year. The motor should be checked, the parts oiled and the freon levels inspected. These repairs will keep your HVAC system running smoothly.

Make sure that your AC is turned off when you are not using it. Sure, the temp will rise, but no one is home anyway. If you leave it on all day, it’s fighting the heat constantly, meaning it’s using a lot of electricity to do its job.

Do not let your house get dangerously hot. Air conditioners can cool a home by just twenty degrees in a short time. This means that if the weather is above 100 degrees, then you’ll still be baking in 80 degree weather at first! This is not a safe and comfortable temperature for you to sleep in.

Look online for a/c sizing calculators so you can really understand the unit size needed for your home or room. Buying a unit which is too big reduces efficiency. Check your manual to learn what it is rated by the manufacturer if you want accurate information.

Find out how many years an HVAC company has been in business before you hire them. Companies that have been around for longer have a proven track record that you can use to decide if they are worth the time and money. Hiring an inexperienced contractor can be risky.

Check reviews online to find professional help. Many Internet sites let customers discuss experiences with certain companies. This is useful for finding people that you wish to work with and those that you don’t.

Having to use a HVAC contractor might be daunting if you don’t have proper information. But, it does not need to be terribly difficult. Hopefully, you’re now ready to tackle any issues that come up with your HVAC system.
