7 HVAC Myths You Should Stop Believing Today in Opelika, AL

December 28, 2021

Several myths surround HVAC systems in Opelika, AL, with some causing severe system damages and reducing efficiency. Understanding the basic facts and debunking HVAC myths can help you extend the system’s life, improve efficiency and maintain comfortable home temperatures. Here are the truths behind the most common HVAC misconceptions and why you shouldn’t believe these myths.

1. Thermostat Location Doesn’t Matter

You probably believe that where you place your thermostat isn’t essential, which is not true. Placing your thermostat too close to air vents or windows might prompt the device to give false temperature readings. When the sun shines directly on your thermostat, it reads that your home is warmer than it is, so the HVAC turns on sooner than it should.

The wrong thermostat placement might also cause energy waste and HVAC failure due to short cycling. It’s best to place your thermostat away from an area that might spike temperatures, as this will cause your HVAC system to malfunction. A qualified HVAC technician can help put your thermostat in an ideal spot for optimal performance and comfort.

2. You Only Run Your HVAC When You Need It

Avoid believing the misconception of shutting your HVAC on and off to save money. Typically, your HVAC system uses more energy during its first five minutes of running than the subsequent minutes. Turning your system on and off hourly consumes more energy than letting it operate non-stop. You should set the thermostat and leave it along or install a smart thermostat and program it to your schedule.

3. Routine Maintenance Is Optional

The truth is that skipping regular HVAC maintenance can expose your system to severe issues, including a premature breakdown. Maintaining your HVAC system is vital in maintaining an efficient system as well as determining and fixing problems as soon as they happen. Hire an experienced HVAC technician to maintain your HVAC at least annually if you want the system to provide optimal comfort and last longer.

Routine HVAC maintenance entails keeping the system safe through regular inspections. An HVAC expert examines all the electrical components and refrigerant levels during a routine tune-up. While routine tune-ups might sound easy, it’s best to leave them to the HVAC pros.

4. All HVAC Systems Are Noisy

Your HVAC unit is probably aging, faulty or nearing its end of life if it produces a loud, distracting and unusual noise. HVAC systems operate at minimal noises and don’t produce loud or unusual noises like banging or squealing. Start thinking of buying a newer HVAC model if your current one is noisy, or hire the pros to unearth the cause of a noisy unit.

5. If You Know Your Home’s Square Footage, You Can Give an Accurate Estimate

The square footage of your home isn’t the only factor to consider when sizing an HVAC system. An HVAC professional considers other factors like the existing ductwork, insulation and air leakage to estimate your heating and cooling needs. Only considering an area’s square footage for HVAC sizing will give the wrong results, eventually reducing the system’s lifespan and efficiency.

6. Use Duct Tape for Duct Leaks

Duct tape isn’t suitable for sealing air duct leaks because it eventually peels and fails to stick well, posing a potential hazard. Mastic sealant and aluminum foil tapes are better for sealing air ducts since they don’t melt. The best solution is to hire an expert if you have air duct leaks, so that they can provide professional sealing that will last longer and improve air duct performance.

7. Change Air Filters Once a Year

It’s best to change or clean your air filters at least quarterly, and monthly if there clog quickly, to prevent airflow issues that result from clogged and dirty air filters. Dirty and clogged air filters restrict airflow in your HVAC unit, causing blower motor and compressor failure and premature furnace breakdowns. You might have to change your air filters more frequently if you live in a dusty location or have pets.
