April is a transition month for homeowners in Whatcom County, bringing milder temperatures, longer days and an opportunity to reduce energy costs before summer arrives. HVAC professionals say small adjustments made in spring can lead to noticeable savings on utility bills while extending the life of heating and cooling systems.
One of the easiest ways to save energy in April is adjusting thermostat settings. With outdoor temperatures fluctuating, many homes no longer need constant heating. Lowering the thermostat by a few degrees or switching to a programmable or smart thermostat can reduce unnecessary energy use. Experts recommend setting thermostats lower during the day and slightly warmer in the evening, depending on comfort needs.
“Lowering the thermostat during the day, or longer periods of time when the system does not need to operate as much can help cut down on some energy usage, depending on what type of system that you have. When dropping the set temperature, I would not recommend lowering it more than 2 or 3 degrees. Raising it back up to normal when you return home by more than 2 or 3 degrees can cause your system to kick into high capacity and overwork itself to get there quickly compared to the slower, constant, efficient approach that a variable speed type system takes to maintain temperature vs. play catch up.”
Spring is also an ideal time for routine HVAC maintenance. After months of winter use, systems may be working less efficiently due to wear and buildup. A professional tune-up can identify issues such as dirty components, loose connections or airflow restrictions. According to technicians at Feller Heating, regular maintenance improves efficiency and helps prevent costly breakdowns during peak summer demand.
Changing air filters is another simple but often overlooked step. Dirty filters force HVAC systems to work harder, increasing energy consumption and reducing indoor air quality. During spring, when pollen levels rise, filters may need to be replaced more frequently. Most professionals recommend checking filters monthly and replacing them as needed.
Homeowners can also improve efficiency by sealing air leaks. Gaps around windows, doors and ductwork allow conditioned air to escape, driving up energy use. Caulking and weatherstripping are inexpensive solutions that can make a measurable difference in comfort and monthly bills.
Heat pump owners may benefit from adjusting system settings in spring. As heating demands decrease, switching systems to an automatic or energy-saving mode can prevent
unnecessary operation. Ensuring outdoor units are clear of debris such as leaves and branches also helps maintain proper airflow.
Finally, April is a good time to evaluate overall system performance. If utility bills remain high despite moderate weather, it may signal inefficiencies or aging equipment. HVAC professionals can provide assessments and recommend upgrades that improve efficiency over the long term.
By making these adjustments in April, Whatcom County homeowners can take advantage of the season’s mild weather, lower energy costs and prepare their HVAC systems for the warmer months ahead.
