Before signing up for a service contract, determine the cost of routine maintenance for your unit and make sure the cost of the service contract is comparable. You may find that it is cheaper to simply pay for the routine service out of pocket.
Find out whether emergency repairs are included. If they are and the price is reasonable, you may want to purchase. If not, you may want to look elsewhere for the service. Always read the fine print before signing, making sure you know what actions on your part could nullify the contract.
Finally, make sure that you choose a company that is honest, trustworthy and reliable. Remember, the service contract is only as good as the service provider backing it. Browse Angie's List to find highly reputable HVAC service providers in your area. With one of these, you can consider an HVAC service contract with confidence.
