HVAC Preventive Maintenance Checklist

air conditioning unit repairYour HVAC system must run efficiently all year long. Since you expect it to last for 10 years or more, you should know that regular maintenance is required. Many homeowners neglect maintenance on their equipment, but that’s not a good idea. Without regular maintenance, you’re sacrificing efficiency and reducing the lifespan of your HVAC unit. Here are some tips for preventive maintenance that will make the process easier.

When to Schedule Maintenance

Before you know what to do, you must know when to do it. Most HVAC systems handle heating and cooling. These must be serviced twice a year. Ideally, this gets done in the spring and fall before you switch from heating to cooling and vice versa. If you only want to do maintenance on the cooling system, you can do that once a year in the spring. Similarly, furnace maintenance should be performed in the fall before it gets cold.

Your outdoor units are exposed to wind and weather all year long. They can get dirty because of flying debris, which is why it makes sense to clean them regularly. It’s a good idea to clean any dirt, leaves, and debris from the inside and inspect the unit for potential problems. Before you start maintenance, it’s important to turn it off so you aren’t injured by the fan blades.

Here are a few other things you should check on your outdoor unit:

  • Check refrigerant level
  • Inspect fan motor and blades for wear or damage
  • Inspect tubing for damage
  • Inspect and clean coils

Indoor Units

Indoor units also collect dust and grime, even though they’re not exposed to outdoor conditions. Your indoor unit probably sits inside of a closed cabinet. It’s a good idea to clean the entire unit regularly. You’ll also want to inspect the burner, ignition system, heat exchanger, evaporator coil, drain pan, condensate drain lines, control box, and wiring. If you’re not sure what any of these are, it’s best to pay for professional HVAC service in Douglasville.

You can still take a look at your indoor unit after ensuring that it’s turned off to see if you notice anything visibly wrong with it. Your HVAC professional may recommend changing out a few parts, much as you would do for your car throughout the years, even if the parts don’t look broken just yet.

Filters

One thing you must do to ensure that your HVAC system keeps running all year long is changing out the filter regularly. When the filter is clogged, it reduces the efficiency of the unit. It also reduces the air quality in your home. Fortunately, filters are cheap and switching them out regularly is easy to do. There are different kinds of filters available, and some are supposed to last longer than a month. It’s still advisable to check the filter at least once a month and change it out if necessary.

Improving Efficiency

Beyond scheduling regular maintenance and changing out the filter, you can improve the efficiency of your HVAC system by properly insulating your home. This ensures that warm or cold air can’t escape the house. You must also regularly inspect your ductwork. It’s possible that it may need to be replaced if too much air is lost through the ducts.
