3 Common Heating and Cooling Mistakes to Avoid
A new year often inspires changes in daily routines, making it a perfect time to rethink how heating and cooling systems are handled. Small adjustments in filter care, vent usage, and AC professional service can dramatically improve comfort, energy efficiency, and system life. This post highlights three common HVAC habits that quietly undermine performance and explains how to replace them with better practices.
Not Replacing Air Filters
An air filter may not look important, but it has a big impact on how well a furnace or air conditioner operates. As dust, pet hair, and other particles collect, the filter becomes clogged. Without regular air filter replacement, airflow through the system drops, equipment works harder, and indoor air quality suffers.
Most homes with standard one-inch filters benefit from swapping them at least every three months, and more often when pets, smokers, or renovation dust are present. A clean air filter allows air to move freely across heat exchangers and cooling coils. That helps maintain more even temperatures from room to room and reduces hot and cold spots.
Good airflow also boosts energy efficiency. When the system does not have to fight a blocked filter, it can heat or cool spaces with shorter run times, trimming utility bills. Less strain on blowers and other components reduces wear and tear, extending the life of both heating and cooling equipment. For such a low-cost item, routine filter changes deliver substantial value.
Blocking or Closing Air Vents
Another habit that often causes problems is closing supply registers or placing furniture directly over air vents. While the goal may be to shut off unused rooms or redirect air, blocking vents disrupts the balance of pressure within the duct system.
When too many vents are closed, air pressure in the ducts rises. The blower must push against this added resistance, which can lead to noise, higher motor load, and shortened component life. Air distribution also suffers. Some rooms become uncomfortable while others may be overconditioned, prompting thermostat adjustments that increase energy use and highlight system inefficiency.
Leaving vents open and unobstructed allows air to travel as the system was designed. If certain areas remain uncomfortable, the better solution is to consult a professional about duct modifications, balancing, or zoning options rather than forcing air away with blocked registers. That approach supports both comfort and energy efficiency.
Skipping Maintenance
Heating and air conditioning maintenance are easy to overlook when the equipment seems to be working. However, skipping routine service is one of the fastest ways to increase operating costs and the risk of breakdowns.
During scheduled heating maintenance and AC maintenance, technicians typically clean burners and coils, check refrigerant or gas supply, verify airflow, and test safety controls. This work helps the system operate closer to its intended efficiency, which can lower energy bills season after season.
Preventive visits also catch minor issues, such as loose wires, weak capacitors, or dirty components, before they cause major failures. That means fewer emergency calls and a longer overall lifespan for the system. Regular service supports more stable temperatures and better indoor air quality, since filters, coils, and drain lines stay cleaner and less prone to mold or debris buildup.
