HVAC Maintenance and Inspections

Heating and air conditioning systems require regular maintenance to help ensure proper and safe operation. Regularly scheduled maintenance on your system is of utmost importance. Whether it is an older system or new system under warranty, it is an important thing to do twice a year- in the Spring and Fall. It is important in order to keep your system running at it’s peak performance and efficiency. It is also important in order to keep any warranties you have protected. Lastly, it is important to address any issues before you experience a costly, critical failure.

These system checks include visual inspection, testing and adjustments of the entire system including the

  • Thermostats
  • Blower
  • Motor
  • Evaporator
  • Coil
  • Condenser
  • Capacitor
  • Blades
  • Pipes
  • Wiring and connections.

Inspection, cleaning and maintenance makes certain your system is ready to handle the new workload right before you switch from Winter Heating to Summer cooling. Between seasons it is a simple thing to run tests and make sure your system is ready to perform at its utmost. Catching problems before they happen can greatly minimize your expenses and downtime at minimal cost.

Detecting a component that is underperforming before it breaks down will help prevent harm to other components in your system. Finding leaks or wiring issues can be large safety precautions as well.

Our HVAC annual service agreement can benefit you in many ways. For a low yearly rate you can take advantage of twice a year maintenance inspections, discounted rates, discounted parts and preferred scheduling. The most important benefit is knowing that your systems are performing properly, safely and at their peak efficiency. Ideally it is best to have your air conditioning system inspected in the Spring before warm weather use and your heating system inspected in the fall before your cold weather use.

Having an annual service agreement automates this process for you and allows you to take advantage of special discounts applied to maintenance agreement customers. They include a discount on Parts and Labor. The twice yearly maintenance will include a comprehensive 23 point (heating) or 18 point (cooling) performance “Tune Up”. This can increase the longevity of your equipment.

A maintenance contract is very important in protecting any warranties you may have on your eligible equipment. Most new equipment warranties are honored so long as the equipment has been properly and professionally maintained over the course of the warranty. Unless this is done, your warranty may be at risk and not honored should you encounter a failure. Air Doctor Heating and Air monitors warranties on all new installations and offers a two year service contract at no added cost with our CFL Warranty. Most warranties are void if you have any alterations, adjustments or repairs by anyone other than a licensed, certified professional so always have any work performed by a licensed professional.

Saving energy costs are a big benefit to having your HVAC systems performing optimally. This will ensure that you are maximizing your HVAC system’s efforts.

We offer Service contracts on new or older equipment. While your older equipment may no longer have warranty protection, Air Doctor Heating and Air can still keep it running is best. If you ever decide to replace your system, Air Doctor Heating and Air can provide you with a Free Estimate. Contact us today!
