When it comes to your home’s heating and cooling system, you know that replacing it can be expensive.

So, getting the most out of your current system should be your goal to delay a large — upward of $4,000 — replacement cost.

Here are some tips that will allow you to increase the lifespan of your heating and cooling system.

A heating and cooling specialist should check your air conditioner at least twice a year.

1. Get Annual Tune-Ups

You need to call a heating, ventilation and air conditioning professional and get HVAC tune-ups twice a year (once for heating and once for cooling).

Get your furnace checked just before its winter use and your air conditioner checked just before the hot months of summertime.

Your tune-up professional will lubricate and inspect all system parts for functionality. They’ll replace filters, clean out drain holes and check your refrigerant levels.

These maintenance visits will ensure that your system is running optimally, and that it will work when you need it most to stay comfortable in your home.

2. Change the Heating and Cooling System’s Filters

Your heating and cooling system has filters that require changing or cleaning every so often. The jobs of these filters are to trap harmful debris and allergens throughout your ventilation system.

It’s a good idea to change these filters every 90 days, at least, so that your system works efficiently and to prevent system failure.

If you don’t change your filters, they will become clogged. This will make it difficult for the heating and cooling system to push air through your ventilation pipes.
