Things You Do That Damage Your HVAC System

Updated: Mar 8, 2023

You might be surprised at the things you do that damage your HVAC system. A home that is just the right temperature is one of the joys of life that everyone can appreciate. HVAC systems have been providing heating and cooling comfort in homes and offices for decades and their efficiency is only getting better with time.

Our air conditioners keep us cool in the hot summer months and our heating systems heat us up in the colder winter months. Knowing what to do to keep your environment comfortable is important. It is easy to see that one might get frustrated when their indoor air quality is not what it needs to be, especially when your ac unit isn’t old enough to technically be malfunctioning.

There are many things that can contribute to an inefficient HVAC system. Some of those are things you might be doing every day, some you might do based on incorrect information you have received about ac maintenance. Regardless of the reason, your actions may be contributing to increased utility expenses such as energy and water expenses. Improper maintenance, an irregular maintenance schedule and worn parts can cause your HVAC system to fail. Read on to find out what else you might be doing that is damaging your HVAC system.

Installing the Wrong System Size

HVAC systems are designed to work efficiently over a designated space or service area. Each system can only efficiently cover an area sized to match its specs in order to be energy efficient and to cool, heat and ventilate properly. Your system must be suited to the specific factors of your home for you to get the full benefits of your system.

If your system is too large for the service area, it will reach the desired setting too quickly and will cycle on and off too often. This not only puts pressure on your system and will eventually cause damage, but it also wastes energy and will significantly increase your energy bills.

In contrast, if your system is too small, it will have to work harder to provide the desired temperatures, using more energy to accomplish this. This pressure will cause faster wear and tear on the system and higher energy bills. The installation of the correct unit, one best suited to your space is essential in not only getting the comfort you need but in saving you money. The HVAC technicians at Wright’s AC and Heat can provide the guidance you need to select the right HVAC system.

Irregular Maintenance

Preventing ac damage or the damage of your other HVAC units will require you to stick to a regular maintenance schedule. Manufacturers always suggest maintenance timelines, but if your environment requires that you need it more often, you should seek the assistance of an experienced HVAC expert.

Your HVAC system will not work correctly if it is not serviced often. Your air conditioning system and heating systems need preventative maintenance or servicing at least every six months to prevent damage. Monthly maintenance involves things you can do on your own, like changing the air filter in your air conditioner. If preventative maintenance is not done, small problems can blossom into expensive ones.

It is also important to schedule your maintenance in the off-peak seasons or just before they begin. For example, heated air will be more important to you during the winter, so get your unit serviced just before the season begins. Whether you have a window air conditioner or central air conditioner, cooled air will be most needed during the hottest months of the year, so servicing your air conditioning system should be scheduled before then.

If you are unsure about your maintenance schedule, contact us for advice. The technician will check to see if the components in the system are working correctly and conduct necessary repairs and cleanings.


Regardless of the type of heating system or HVAC system you have, it will surely not perform optimally if the airflow is blocked. Vents blocked by trees and other debris will restrict airflow and reduce the efficiency of the unit. Even worse, units with dirt and dust can also cause air quality issues in addition to reducing the airflow.

Make a conscious effort to not place any furniture or other item in a position to block your vents. Outdoors, trees and bushes must be trimmed and removed to ensure that the condenser (outdoor unit), if you have one, is not blocked.

Clean and service your unit regularly to prevent a buildup of dirt, dust and other debris.

Improper Thermostat Settings

Your thermostat controls the temperature of your house. Strain is added to your system when the indoor temperature differs greatly from the outdoor temperature. It is wise to set your thermostat as comfortably close to the outdoor temperature as you can tolerate. The lower the degree is on your thermostat, the lower energy consumption you will have. Not only will this reflect on your energy bills, but you will also relieve some of the pressure on your HVAC system.

Additionally, ensure that you use a programmable thermostat to control your unit instead of turning it on and off throughout the day. Turning it off and on regularly will result in system damage and increased energy waste.

The efficiency of your HVAC system and its longevity is dependent on how well you take care of it. Make preventative maintenance a part of your life and your unit will last you for many years to come.
