Heating and air conditioning equipment, no matter what type you have, should be inspected, cleaned, and serviced at least once a year. It is best to check the heating system in the fall and the air conditioning in the spring. However, what's more important than scheduling the maintenance session is how often you schedule it. Your air conditioning systems should be checked by a professional once a year. So, if you have a standard central air conditioner or an oven, each of these units must be maintained every year.
If you have a heat pump system that you use year-round, you'll want to schedule this service once every 6 months. At a minimum, you should try to have your air conditioner serviced every year in early to mid-spring. However, for optimal performance, it would be in your best interest to have your unit serviced in the fall as well. An HVAC contractor will focus on your boiler to prepare your system to cope with heating demands once temperatures drop.
However, how often you schedule your maintenance session is more important than when you do it. Once a year, have your HVAC systems inspected by a professional. If you have a typical central air conditioner or boiler, you should check each of these pieces of equipment once a year. If you have a heat pump system that you use all year round, this service should be scheduled every six months.
Adequate air circulation for your HVAC system is called ventilation, and it's something you should consult with your HVAC specialist during new installations and regular maintenance. One way to save money and keep your heating, ventilation and air conditioning system in optimal condition is to take out an annual service plan for heating, ventilation and air conditioning.
