There are those of us who know how to perform HVAC preventive maintenance. And then there is everyone else – those who understand the importance of maintaining furnaces and air conditioners and those whose involvement ends at the thermostat.

The most important element of any furnace and air conditioner maintenance plan is changing your air filter on a regular basis. Every three months at a minimum. Yes, it’s true. HVAC maintenance can be as simple as a filter change most of the time. Filters are cheap, especially compared to emergency service calls. Often, the source of serious furnace and AC problems can be traced back to a dirty filter.

A dirty filter restricts the flow of air through your air system. Without proper airflow, your furnace and air conditioner work harder, components get overheated and sensitive parts fail. Isn’t it ironic that the cheapest and easiest piece of your HVAC system to replace has the ability to bring the whole unit to a crashing halt? Seriously, simply keeping your filter clean can spare a lot of frustration and expense.

If that isn’t enough to convince you to change your filters, here’s another good reason: a dirty filter could void your warranty coverage if the failure is linked to restricted airflow. Remember that some components of your furnace and AC are rather expensive to replace. You don’t want to foot that bill when a new filter runs a couple of dollars.

Beyond changing your air filter, it’s best to leave the rest of preventive maintenance to your HVAC company. Unless you’re a qualified HVAC technician, it’s impossible to know how to do the required maintenance.

Case in point: An HVAC technician carries a safety device that determines whether or not the furnace burner is lit. These tools take less than a second to determine ignition. Without these devices, homeowners could be pumping raw gas throughout the room or house before they realize it. Serious HVAC preventive maintenance can be dangerous. After all, HVAC involves intricate systems and attempting preventative maintenance yourself could damage components otherwise covered by warranty depending on your coverage.

Preventative maintenance is the best way to maintain your AC and furnace.  Leave it to the heating and cooling experts at United Heating, Cooling & Plumbing.
