3 Common Mistakes Homeowners Make With Their AC System


Air conditioning is key to keeping your family comfortable when temperatures are hot outside, but it is also important for removing humidity that affects the home's indoor air quality. As a homeowner, you may understand the essential nature of your cooling system. Unfortunately, you may not be placing enough time and energy into learning how to operate and maintain your air conditioning properly. By avoiding these common mistakes, your AC system will run more efficiently and effectively.

Ignoring Noises

All appliances and mechanical components make some noise from time to time. A light humming and even a clicking sound are both normal as your system is cooling or when you first turn your air conditioning on. However, loud noises are signs that your air conditioning unit is in distress. Ignoring these sounds could lead to decreased comfort, increased energy bills, and a failed system that needs to be replaced.

A banging or buzzing sound in your unit may be a few different things. In most cases, this noise stems from a loose component or piece of debris inside your system. Inspecting and cleaning the unit is imperative, but you must first turn off all power to the unit to avoid electrical shock.

Once the power is off, undo the nuts and bolts on the unit's exterior cage. Remove it carefully and inspect the interior for visible signs of debris. Ensure all components are secured properly. If you notice the fan blades are warped, you will need to have these replaced.

Remember that many noises may also signal an electrical issue. If your compressor or motor stop working, you may hear loud buzzing or humming sounds. In addition, your system will struggle to cool your home.

Improper Maintenance

One of the most common mistakes homeowners make is not maintaining their AC system properly. Consider setting up a schedule with a HVAC contractor to come and perform system checkups seasonally. These checkups will ensure your system is ready for the main heating and cooling systems. If any issues are found, contractors can offer suggestions to make repairs that will help your system run efficiently.

Of course, there are tasks you can do on your own. Changing the AC filters regularly is one of the most important parts of maintaining your system. While ductwork moves conditioned air into your home, dirt, dust, and other allergens may also become swept in through the ducts. The filters are used to catch these allergens, preventing them from coming into the home.

If your filters are clogged with dirt, dust, and debris, air will struggle to move through the vents properly. This decreased airflow causes your system to work harder to cool the home. The harder the system works, the more energy it uses. Therefore, replacing your filters each month during the cooling season will help your air conditioning run without wasting energy.

Blocking Returns

A heating and air system consists of a side for supply and a side for return. Both sides are important for conditioning the home properly. Conditioned air comes through the supply vents. The return vents draw cold, old air into the ductwork, where it is then moved to the unit to be reconditioned.

Depending on where your return vents are located in the home, you may have furniture, plants, or décor blocking them. If these return vents are blocked, air will struggle moving out to be conditioned, which can increase the time and energy needed to cool your home properly.

Proper understanding, use, and maintenance are important if you want your air conditioning to run effectively. This guide and your contractor will help you avoid common mistakes that decrease the efficiency of your AC system. For more information on AC maintenance, contact an HVAC contractor in your area.

Understanding Advances in HVAC Systems

When our air conditioner broke last year, I was fairly confident that we would be left trying to choose a similar system for a bunch of money. However, our friend who works as a general contractor explained that there were all kinds of neat advances in HVAC systems that might help us out. He explained that we might be able to enjoy a quieter system or one that filters our indoor air more effectively. We liked the sound of that, so we started shopping for a new system. After finding an air conditioner that was perfect for our place, we started this blog to educate other homeowners about new technology.
