HVAC systems have become incredibly efficient over the past few years, helping homeowners pocket significant savings on energy costs. However, making the following mistakes can easily erase those savings and cause energy bills to skyrocket. Here are a few common HVAC mistakes you should avoid making.

Common HVAC Mistakes To Avoid:

1. Improperly sized unit

A system that’s too big or too small will fail to maintain proper temperature in the home and shorten its lifespan. An oversized unit will cycle on and off in short bursts and won’t be able to control humidity or air circulation in the home. On the other hand, a small HVAC system won’t reach the temperature set on the thermostat and have to work harder and longer, using more energy and increasing wear and tear on the system.

2. Very restrictive air filter

A highly restrictive air filter may sound like a good idea, since it can trap particles as small as 0.3 microns, but it will also make it difficult for air to pass through the system and into the home. If you’d like the HVAC system to also function as a whole-house air filtration system, be sure to let the installer know before signing the contract so that he can make the necessary adjustments.

3. Outdoor coils installed too close to obstructions

If you try to hide the outdoor unit by planting bushes and other landscaping around it, this can cause the air moving through the unit to be up to 20 degrees higher than the ambient air. This will cause energy consumption to increase by up to 20%.

4. Refrigerant additives

HVAC manufacturers carefully design systems, including the oils and additives used in the compressor to maximize performance. If you start adding different additives, you will see negative results and potentially damage the system.

5. Using chemical cleaners on coils

It’s important to keep the HVAC system clean to maximize efficiency and reduce wear and tear. The best way to clean coils is with a garden hose. But if you start using cleaners with acidic or alkaline substances, you risk damaging the coils. Stick to water and you’ll keep your system in good condition.
