Few people truly understand the ins and outs of HVAC. This is something you must educate yourself on for emergencies. Reading the article below will be instrumental in helping anyone figure out what to do when trouble occurs.

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.

Make sure the equipment you are buying is ENERGY STAR compliant. It may seem a small thing, but it isn't. Products that are ENERGY STAR compliant can save you a lot of money in energy costs over the year. It can be over $100 easily, sometimes a lot more.

An Air Compressor system is a really expensive investment. This is why you should do some browsing before purchasing your system. Try to find a good sale so you can get your system at a discount. Check out a couple of sites before making a decision.

Fall is a hard time on HVAC units. Frequently clean the fan grill when trees are shedding leaves. When blockages restrict the flow of air to the fan, you could end up with serious issues on your hands.

Place your HVAC unit in the shade to boost efficiency. It will reduce the temperature of the air going into the unit, meaning that it will not have to work as hard to cool it.

It is very important that your HVAC system is serviced two times a year. Most homeowners choose to have their unit inspected during the spring and the fall months. This helps prepare for the coming weather changes of summer and winter. Even if everything seems okay, it doesn't hurt to check things out.

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.

Compressor

A good place to place your compressor unit outside is in a shady spot. The cooler the air which goes in, the less work the unit will have to do.

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, air conditioners collect ice. The drain line might also freeze over. If you notice this, switch your thermostat to fan only to disable the compressor. Once you know the problem, contact a local HVAC professional and let them know what's going on in your system.

When you are looking for a service provider to perform service on your Air Compressor system, look for a company that stands behind their work. This is especially important if your compressor or condenser is being repaired. Repairs to these two things are extremely expensive, so you want to ensure that the service provider warranties their work.

Do not close your vents. Keep air vents open and unblocked at all times. Many people believe that closing off a vent will save them money on cooling costs. This is not true. It can actually damage your HVAC system. Closing vents can cause your cooling coil to freeze and damage the compressor.

When you are looking to buy a new air conditioner, consider your climate. If you live in a hot, dry area, then an evaporative cooler will be your best bet. If you live in a humid area, opt for a compressor-style unit as it's the only one which will work.

If your outdoor compressor unit sits in the sun, consider building a shade over it. Air in the shade is about 5 degrees cooler than air in the sun. This can have a significant impact on your cooling bill. When done properly, you could see up to a 10 percent savings over the season.
