Debunking These 8 Myths About HVAC

Are you worried about these common HVAC myths? Dispel the misconceptions about heating and cooling to reduce your energy bills and enhance home comfort.

Nothing is as crucial to maintaining total comfort and peace of mind than your HVAC system. Despite this, many homeowners are misled by common HVAC myths that leave you with poor performance, higher costs and comfort problems. We’re here to correct these misconceptions to make sure your home comfort system works as efficiently as possible.

Myth 1: You Should Replace the HVAC Filter Every Year

Even though it just sits there, changing your filter annually is rarely enough to ensure your air quality is safe. This time frame is only appropriate if you have a basic filter, no pets, no allergies and a small household size. Otherwise, you should replace the filter every 30 to 90 days as per the manufacturer’s recommendations.

Myth 2: It Doesn’t Matter Where the Thermostat Is

Quite the opposite, your thermostat’s location is absolutely vital for truly effective heating and cooling. The thermostat should be installed a safe distance from direct sunlight, drafts and sources of heat as well as the windows and doors. It’s best to find an interior wall in an open part of your home the daily indoor temperature.

Myth 3: Routine HVAC Maintenance Is Unnecessary

Routine HVAC maintenance is a budget-friendly and consistent expense that delivers higher savings by making sure your HVAC system enjoys:

  • Boosted efficiency: Professional maintenance the easiest way to keep your system running at its best, lowering energy use and your utility bills.
  • Reduced repair needs: As we complete a maintenance visit, our technicians can spot and repair small problems like a broken bolt or a clog in the air filter before they cause larger issues. Taking such a proactive approach helps sidestep unexpected breakdowns and the costs that come with.
  • Longer system life span: Consistent upkeep assists your HVAC system in running smoothly, extending its life by some time to avoid premature replacement costs.

Myth 4: A High-Efficiency HVAC System Is All It Takes to Lower Energy Costs

While it’s a strong start, installing a high-efficiency HVAC system is just the beginning maximize efficiency and minimize those monthly energy bills, it might be a good idea to employ other helpful strategies:

  • Guarantee accurate sizing and installation: Your HVAC unit must be installed and sized correctly to avoid inefficient operation and increased energy costs.
  • Enhance the amount of insulation and sealing in your house: Increasing insulation levels and tightening the seal of windows and doors around the house keeps the AC from getting out. Steps like increasing attic insulation, sealing cracks in walls, and replacing old windows and doors help maintain consistent temperatures and reduced energy waste.
  • Get a programmable thermostat: This innovative HVAC control allows you to program energy-saving temperatures based on your schedule. Set and forget your thermostat with automatic setbacks to minimize power use while you’re sleeping or out of the house.
  • Keep air flowing: Keep all supply and return vents clear and use ceiling fans to circulate more air throughout your home. This distributes heated or cooled air more consistently for better comfort levels and efficiency.

Myth 5: Duct Tape Is a Good Way to Seal Leaky Ductwork

Plenty of people fall for this myth because duct tape has a very similar name to your ductwork. Sadly,  it won’t be able to withstand the temperature extremes and air pressure inside HVAC systems, making it a bad choice for sealing duct leaks. Alternatively, use specially made mastic sealant or aluminum foil tape for more efficient results.

Myth 6: Square Footage Is the Sole Factor to Determine HVAC Sizing

While it may surprise you, sizing the HVAC system correctly is an intricate process that accounts for much more than how big your home is. Here are the other factors an experienced heating and cooling technician should take into consideration when choosing the appropriate size of HVAC system:

  • Climate
  • How big your windows are and where they’re placed
  • How well your home is insulated
  • Air infiltration rates
  • Which way your house is oriented 
  • How many people live in your house
  • The amount of heat your home collects over time

Myth 7: Opting for High Efficiency HVAC Air Filters s Always the Right Choice

Perhaps you’ve heard about the wonders of HEPA filters and wish to put one in your HVAC system. At the same time, while higher efficiency air filters filter out more contaminants, they also reduce air circulation. Remember to use a filter that’s appropriately matched to your HVAC system to avoid a drop in efficiency and putting too much stress on it. In many cases, this is easiest with a mid-range pleated or electrostatic filter. Your Expert technician can help you select the best option.

Myth 8: Understanding My HVAC System Isn’t Necessary

You shouldn’t have to be a heating and cooling Expert to use heating and cooling, but understanding the basics is very beneficial. A little knowledge goes a long way toward keeping your HVAC in good shape, diagnosing issues and working closely with your technician.
