When it comes to selecting an HVAC system, there are many decisions to be made. While you can often trust the guidance of a trained professional, it is good to have a basic knowledge of your own so that you’re comfortable in knowing you are not buying too much. This article contains some HVAC basics that will help you to be an educated buyer.

If you must hire someone to help you out with your HVAC system, be sure to learn about all of the requirements your state has legislated regarding licencing and insurance. You need to be able to ask anyone you plan to hire if they meet these requirements before you hire them.

Check out the system that you have before you call a professional. Write down the make, model, and any maintenance history. This helps make sure the contractor has the information they will need.

When a contractor gives you a list of references, be sure to make use of it. Call the people on the list and ask about the quality of the work, how closely they came to their quote and whether or not the work was completed according to the promised timeline.

Get any agreement with an HVAC contractor in writing. Some contractors try to skip over this step and charge customers a fortune. If you have a certain price and warranty in writing, they cannot go back and change this information. If they do, they could have a lawsuit on their hands.

Before you hire anyone to do any work on your HVAC, be sure to get a written estimate which has itemized costs listed on it. This will ensure that comparing one contractor to another will be simple as you can see what one offers that another doesn’t, or what price they’re charging for the same items.

When the spring comes and the days begin to warm up, call in a pro to give your HVAC a once over. This will ensure that your air conditioner works as expected all summer long, stopping you from sweating it out when you least expect the system to fail.

Clean the coils on the condenser fan from time to time. Don’t forget to disconnect the power first. After you have turned the power off, you simply remove the grill and the blades to perform a gentle cleansing.

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.

Make sure that the HVAC contractor you plan to hire does not use subcontractors to do their work. Many people use this as an excuse to shirk their responsibility in the event that something goes wrong when your system is being worked on. Only allow this if there is a note in the contract about what will happen if there is an issue.

Before you get into the hot summer months, make sure to schedule a tune up for your current HVAC system. This is very important to keep issues from popping up with your system. It’s a small cost to pay compared to the large bills to fix issues that could arise.

Purchasing an HVAC is typically confusing, but you are now armed with the information you need. Use it when discussing your choices with a professional to make the buying process easier and the end result one you are happy with. This will help to make your home a comfortable one all year round.
