How to Make Your Heating and Cooling System Last Longer

One of the biggest mistakes a homeowner can make is neglecting their HVAC system. This type of neglect can result in premature failures of equipment that otherwise, with proper maintenance, would have lasted many years. Additionally, HVAC manufactures can void warranties on parts when they are not properly maintained.

But where should homeowners start? There are general rules of thumb when it comes to typical maintenance on an HVAC system. Following this handful of tips is the best thing you can do to keep a system in premiere shape for a more extended period. I mean, who doesn’t want their HVAC system operating at its maximum performance?

Important heating and cooling system maintenance tips:


  • Schedule annual pre-season check-ups

First and foremost, it’s imperative to stay on top of the scheduling maintenance of your HVAC system. Hiring an HVAC professional contractor to do a routine check-up of your system is one of the best ways to allow it to run for many years. Scheduled maintenance will let you find issues early and resolve them quickly before the efficiency and health of your HVAC system starts to decline. The best times to schedule these routine check-ups are in early spring for your cooling system and early fall for your heating system.


  • Check humidifiers, UV lights, air pumps, zoning systems, accessories, etc.

Some homes have additional equipment working in cohesion with their regular heating and cooling system. If this is the case, you want to ensure that these additions are getting regularly maintained as well. Typically, an HVAC professional contractor can check these out at your scheduled maintenance appointment.

This can increase energy costs and damage your equipment, leading to early failure.” So, not only can old filters run your HVAC system into an early grave, but they also cause you to spend more money than you need to on your energy bills

Pro tip: next time your HVAC contractor is at your home for a check-up, have them show you how to check your filters. Knowing the condition of your filters will save you time and money by only getting them swapped out when necessary.
