A tune up in the Spring can prevent your air conditioning system from going on the fritz later, when the weather is so hot that you won’t want to be without AC for even a few hours.

It typically costs less than $150 to have a professional inspection of your system, and it’s well worth the money.

Some contractors offer an annual preventive maintenance agreement, which will cost a few hundred dollars a year and typically includes fall and spring inspections of your HVAC system and discounts on repairs and equipment. Depending on services offered in your area, it may be a better deal to pay as you go for individual inspections.

Either way, your cooling system will get attention from a qualified, licensed service technician who is trained to spot problems most homeowners overlook. The tech might even alert you if a small repair now will prevent your family from sweltering this summer during an air conditioner breakdown.
