What Steps Can I Take to Prevent My HVAC Unit from Breaking Down Over Time?

A maintenance agreement is the number one step you can take to protect your HVAC system, but there are few other things you can do.

A professional HVAC maintenance agreement from a company you trust is the best way to avoid heating and cooling repairs and the need for replacement due to general wear and tear. This kind of preventative care prevents small issues from growing into larger ones. But there are also a few things you can yourself do to improve the efficiency of your air conditioner, save money, and help prevent breakdowns.

With summer here, there will be many hot days ahead, so now’s the time to spruce up your central air conditioning system. Here are a few tasks you can do now in addition to your maintenance agreement to set your HVAC up for summer success:

Change Filters Often

With central heating and air conditioning units, it is important to keep the air ducts flowing freely, and keep them free of any excess dust or dirt build-up. Over time, this build-up can become extreme and often lead to blocking the air conditioner vents. Little to no air flow is a big problem on the hottest day of the year!

Make a habit of cleaning and/or changing your filter about once per month to keep it clean and free, so the AC can run at peak efficiency. This will help you to avoid the need for more extensive maintenance and repairs in the long run.

If you have visible access to the fan motor and wheel assembly, you can also check the dust build-up in this at the same time you change your air filters. Every central air conditioner is tied to the efficiency of the fan motor inside the furnace. If there is excessive or visible dust build-up, hire a licensed HVAC company to clean your system thoroughly. Some bigger jobs are best left to the pros.

Keep Thermostat around 78 Degrees

Many people believe you should turn your thermostat to 78 degrees when you leave for vacation, but tend to keep it around 74 or lower other times. Remember your cooling unit will kick on any time the temperature falls below the temperature you have set your thermostat. So, if you set it at 78 and leave it there, rather than moving it up and down to your comfort level, you will have more relative cooling in your entire house, save energy by not overtaxing your air conditioning unit, and avoid having to worry about the thermostat or surprisingly high bills each month.

The summer months are usually the costliest on the energy bill for most people, but it is even more so if you are constantly moving the thermostat around or putting it really low to 68 degrees or lower. This can cause your HVAC to overwork, which is hard on your system AND hard on your bank account.

Close Curtains and Blinds during the Hottest Days of the Summer

Many people don’t realize how much air is lost during the summer due to the sun coming into their homes. People like to open windows too, which lets most of the cool air escape quickly. Teach everyone in your home to keep blinds, curtains and windows/doors closed when it is at the peak high temperature times to save energy and keep the cool air inside. If you do this regularly during the hot summer months, you will save money on your energy bills and your system won’t have to work so hard to keep you nice and cool inside.

Taking these steps for preventative maintenance is a great idea to prolong the life of your HVAC, but to really make the most of your system you need to have a professional maintenance agreement in place.
