There’s nothing worse than coming home to a stuffy house on a hot summer day or being jolted awake by a blast of cold air on a winter morning. Thankfully, there are some steps you can take to help your HVAC units keep your home comfortable all year long. By following a few simple tips, you can maintain your units and keep them running smoothly for years to come. So, whether you’re dealing with the dog days of summer or the dead of winter, follow these tips to keep your home at the perfect temperature.

1. Check Your Air Filters Regularly

One of the most important things you can do to maintain your HVAC units is to check and replace your air filters regularly. Depending on the type of filter you have, you may need to replace it every few months. Clogged or dirty filters can restrict airflow and cause your unit to work harder, which can lead to higher energy bills and premature wear and tear. Be sure to check your filters regularly, and replace them as needed. Your HVAC units will thank you for it.

2. Clean Your Vents and Registers

Another way to keep your HVAC units running smoothly is to clean your vents and registers. Over time, dust and debris can build up on these surfaces, restricting airflow and reducing efficiency. To clean your vents and registers, simply remove them from the wall or floor and vacuum away any dirt and dust. Cleaning your vents and registers is a quick and easy way to keep your HVAC units running at peak performance.

3. Schedule Annual Maintenance

According to, a new HVAC unit can last 12 to 20 years with proper maintenance. To help your unit reach its highest lifespan, it’s important to have it serviced by a professional at least once a year. During a maintenance visit, a technician will clean your unit, inspect it for wear and tear, and make necessary repairs. They may also perform tests to ensure that your units are operating at peak efficiency. In addition to prolonging the life of your HVAC units, annual maintenance can also help you avoid costly repairs down the road. So be sure to schedule a visit from a professional every year.

4. Keep Your Outdoor Unit Clear

If you have a central air conditioner, it’s important to keep the outdoor unit clear of debris. During the fall and winter, leaves can fall and build up around the unit, which can block airflow and cause it to overheat. In the spring and summer, pollen and dust can accumulate on the unit, reducing efficiency. To keep your outdoor unit free of build up, remove any debris accumulated around it.

You should also trim back any trees or shrubs that are growing near the unit, as they can block airflow and cause the unit to overwork itself. By keeping your outdoor unit clear, you can help ensure it runs smoothly all year long.

5. Invest in a Programmable Thermostat

Investing in a programmable thermostat is a great place to start if you’re looking for a way to save money on your energy bills. A programmable thermostat can help you save money by allowing you to set specific temperatures for different times of the day. For example, you can set the temperature lower when you’re away from home or asleep and higher when you’re home and awake.

6. Know When to Replace Your Unit

Although proper maintenance can prolong the life of your HVAC units, eventually, they will need to be replaced. For example, according to Bob Vila, the typical furnace lasts for about 15 to 20 years. If your furnace is nearing the end of its lifespan, it’s important to start looking into replacement options.

The same goes for your air conditioner. Remember, not only does upgrading your unit improve the indoor air quality, but it can also save you money on your energy bills. Remember, the most energy-efficient AC units require 30% to 50% less energy to provide the same amount of cooling as AC units from the mid-1970s.

By following these simple tips, you can keep your HVAC units running smoothly all year long. So be sure to put them into practice today.
