The many advantages of routine maintenance

Just like a car, your HVAC system needs regular maintenance to operate at peak efficiency and performance. Regular preventive maintenance also helps to extend the lifespan of your system and can help detect potential problems before they occur, avoiding a costly breakdown or part replacement. Another, less-obvious benefit of regular system maintenance involves indoor air quality, which can be adversely affected by dirty filters, coils and blower parts within your HVAC system. Regular cleaning of these components significantly reduces contamination of your indoor air, making for a healthier household and happier living environment.

Air conditioner maintenance

Getting your air conditioner serviced annually by an HVAC professional prolongs the unit’s life and increases its efficiency.


Furnace maintenance

Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. In some cases, dirt buildup can even cause the furnace to overheat. Scheduling an annual checkup for your furnace is the most important part of regular furnace maintenance.


Indoor Air Quality maintenance

Maintaining the Indoor Air Quality (IAQ) of your home not only makes you feel better, it also helps you breathe better. Keeping your HVAC system clean and properly maintained goes a long way toward improving IAQ, but there may be other things you can do to keep your home’s air healthy and fresh.


Scheduling your annual HVAC maintenance check

When it comes to preventive maintenance, there’s no time like the present. Heating and cooling tune-ups or preventive maintenance can be performed at any time of the year. Your experienced Lennox Dealer knows how to check the operation of your HVAC equipment under all kinds of conditions and during every season. For maximum system effectiveness, it’s advised that you have at least two tune-ups per year — one for your heating system and one for your cooling.

Pre-service checklist

Before a visit from your Lennox Dealer, it may be helpful to review this list of tips so that you are well prepared.

  1. Take a look at our Troubleshooting page to see if any of your questions can be answered prior to your maintenance visit.
  2. Make a quick inventory list of where all the units in your system are located, including indoor unit, outdoor unit, circuit breaker, utility meter, etc.
  3. Be prepared to share basic information about how your equipment is operating: Have you noticed any problems? If so, do you know what seems to trigger the problem and how long ago the problem began?
  4. Be sure an adult, 18 or over, is able to legally allow entry into your home.
  5. Often technicians will confirm an appointment prior to arrival. Please have a phone easily accessible.
  6. If your home is rented, speak with your landlord in advance.
  7. If the heating or cooling equipment is located in a closet or an attic, or is blocked by a piece of furniture, do your best to provide easy accessibility for the technician.
