Seven Things You Should Not Do To Your Home Air Conditioning Unit

Here are a few considerations when conducting air conditioner preventative maintenance:

1. Never Forget To Check & Change The Air Filter

One of the pros of an air conditioner is that it can filter dust and contaminants for better air quality inside your home. However, HVAC air filters cannot clean or change themselves. Neglecting to check and replace filters can result in a drop in AC efficiency and home comfort.

You should check the air filters once a month and change them at least once every two to three months. They need to be replaced more frequently if you own pets. Consult your HVAC professional if you do not know how to do air filter replacements. They can show you how to do it on their next air conditioner maintenance visit.

2. Don’t Block The AC Condenser

The condenser needs to have a lot of room in its perimeter so it can pull in air. You shouldn’t put objects near this outdoor unit. Make sure that the area around it is clear so it has optimum airflow and cost-efficiency. You may be tempted to plant around the condenser, but it isn’t recommended to place plants too close. Make sure that bushes, flower plants, and other vegetation are several feet away from the condenser. Keep in mind that your condenser requires free-flowing air so that it can last longer.

3. You Should Never Leave Your Air Conditioner Off For Too Long

You may think it is a good idea to keep your air conditioner off for days at a time. However, air conditioners need to run. Make sure to turn on your air conditioner when the outdoor temperature isn’t as high. Leave it on for a few minutes every day or two so that mold and dust do not settle inside your air conditioner.

4. Don’t Crank The Air Conditioning Unit

An air conditioner that’s constantly running may be because of one of two reasons. The first reason is that your area is experiencing extreme heat. The second reason is that the thermostat sensor is set too high. It isn’t surprising that there will be days when you need to run your air conditioner more, but try not to crank up the sensor too high while keeping your home comfortable. You can also take advantage of cooler days and nights to let your air conditioner rest for a while. The longer the air conditioner runs, the harder its parts will work and the more likely they are to break down sooner.

5. You Should Never Try To Power Wash An AC Unit

Spraying your air conditioner using a powerful hose or submerging it in water are not the ways you should clean your cooling unit. Never try to use a powerful approach to do so. Instead, brush out the leaves and wipe the debris inside the outdoor condenser. If more cleaning is required, have a certified and experienced HVAC technician do it. They have the tools and expertise needed to clean your air conditioner properly. Contact an HVAC expert to book a tune-up immediately.

Having your air conditioner inspected and tuned up once a year can prevent small problems from escalating into big and costly ones. Neglecting to get your system inspected and maintained means you risk costlier repairs, reduced efficiency, and more breakdowns. Your reliable HVAC tech will check the system and do the needed maintenance so you don’t have to worry about your cooling unit breaking down when you need it the most. HVAC maintenance helps lower your energy bills and promotes a long system lifespan. Now is a good time to schedule an air conditioner tune-up if you haven’t had one in a while.

7. Do Not Perform DIY Air Conditioner Repairs

Untrained and inexperienced individuals won’t know the ins and outs of maintenance, searching for solutions, and conducting the necessary repairs on air conditioners. Keep in mind that small mistakes can eventually cost you more than hiring an HVAC technician to do it right at the onset. The best option is always to call in experienced and certified HVAC professionals when you need air conditioner services, like installation and maintenance. Make sure to do your homework and research an HVAC company’s reviews, references, licensing, and insurance coverage. The right HVAC technicians have the needed training and education to do quality work on one of your home’s most expensive systems.
