Your HVAC might just be your home’s best feature, especially when it’s hot outside. And if there are issues with cooling, it can quickly turn into an expensive and cumbersome appliance. Uneven airflow, spotty heating and thermostat issues are all common issues that you can fix — without getting an expert involved. So before you start shopping for a new system, here are a few things you can do that will help maintain your HVAC like a professional. With our tips and quick list of common problems, you’ll learn what changes to make and signs there may be something wrong.

What to Look Out For

  • If your HVAC seems to be working, but there’s no change in the temperature of your house, you might have a clogged condensate drain line. Check for any water puddles near your system, if there’s a clog the water in the tray can eventually overflow.  A float switch in the tray can cause the unit to turn off as well to prevent water overflow. Use a stiff, thin wire brush to help loosen the clog or use a vacuum to help suck out debris.
  • If the air feels like it’s coming out more from one vent, but not the other, you may want to consider updating your air vent cover. Our handcrafted and lab-tested air vent covers ensure even air distribution and maximum airflow with a decorative look that emphasizes your style.
  • Pop and bang noises from your air vents can be a sign that you should check your ducts. While it’s common for them to make noises as the ducts expand and contract with the shift in temperature, rattling and shaking can be a sign that the connectors have come loose.
  • If you notice that your AC unit is iced over, this could be a sign that your evaporator coil got too cold or that there are low refrigerant levels. Routine maintenance and cleaning can help keep your system in working order.
  • Check that no more than ¼ of your home’s air vent registers are closed. Shutting off the supply is a common way to save money by not heating or cooling unoccupied rooms but if too many are closed, your HVAC system can experience some issues.
  • Blocked vents and registers can cause some rooms to feel a significant difference in temperature, even if the vent is open. If you have furniture in front of your vent to block the unsightly look, you might be doing more harm than good. Consider switching out the vent cover with something more decorative, and safe for your HVAC.

Tips to Easily Maintain Your HVAC System

  • Develop a maintenance plan by scheduling routine services.
  • Routinely replace your air filter so dust and allergens don’t build up. Set a calendar reminder on your phone or purchase a “smart” filter that connects to your device for alerts.
  • Give your AC and electricity bill a break. You can use ceiling fans to help circulate the air in the room you’re in, rather than the entire house. And programming your system to only turn on during certain hours will ensure it doesn’t run all day.
  • Clean things up to improve efficiency. In fact, systems that haven’t been cleaned in the last three years often see an immediate energy savings of 10%. And be sure to check your outside for debris and weeds and on a regular basis.
  • Take a look at the condenser coils. The U.S. Department of Energy says that a dirty condenser coil can increase energy consumption by 30% as your HVAC works unnecessarily harder.
  • With a bit of routine maintenance and knowledge about your HVAC system, you can keep it up and running for years and save money long term without bringing in the experts for every little thing. See other simple tricks, ideas and tips about air vents on our blog.
