A: You need to have a heating and air conditioning expert come look at your furnace. However, do not be surprised if they recommend you get a new heating system. It may be much more efficient and economical than an older one that may continue to break down.

Although heating and air conditioning companies usually charge for service calls whether or not you choose to have them repair the system, they almost always give free estimates on installing or replacing systems. If you decide to buy a new one, don't automatically sign a contract with the first company that gives you an estimate, even if you think you want to hire them for the job. New equipment is too large an investment to make a snap decision, and reputable firms will respect your desire to do your homework and get comparable bids.

Be sure to talk to at least three different companies and carefully compare their bids for the size of system recommended, manufacturer warranties on both parts and labor, and any extra ductwork they may recommend before making a final choice. Collecting competitive bids is always the best way to make sure you have all the information you need to choose the best product, as well as, the service provider you would prefer working with.

To locate a reliable heating and air conditioning specialist to come look at your furnace and determine whether it can be repaired, or would be more economical in the long run to replace it, please visit Home Advisor. Submit a service request for the kind of furnace you have, and be matched with the ideal service professional in your area.
