With the 2026 summer season approaching, Alabama HVAC contractor Engle Services LLC has released a guidance report aimed at helping homeowners reduce cooling costs during the extreme heat typical of central Alabama summers. The report, published on engleservicesheatingandair.com, covers thermostat management, filter maintenance, warning signs for A/C repair, and the cost benefits of heat pump installation.
According to the U.S. Department of Energy, setting a thermostat to 78 degrees Fahrenheit when occupants are home and raising it by 7 to 10 degrees during work hours can reduce cooling costs by up to 10 percent over the summer. The company recommends programming schedules to match daily routines, as manual adjustments often lead to the system running harder during peak afternoon heat. Ceiling fans can help by circulating air, but homeowners should remember that fans cool people, not rooms, so running them in empty spaces wastes energy.
Routine maintenance is another key factor. A clogged air filter forces the system to work harder, so the company advises changing standard 1-inch filters every 30 days during peak cooling months and scheduling a professional maintenance visit at least once per season. During a tune-up, technicians inspect refrigerant levels, clean coils, check electrical connections, and test airflow—steps that directly affect efficiency and prevent costly breakdowns.
Early detection of issues can save money. The report lists warning signs such as uneven cooling, unusual noises, ice on refrigerant lines, or rising energy bills without a change in usage. “We see a significant spike in service calls every July, and in many cases, the homeowner noticed something off weeks earlier but waited,” said Marcus Engle, owner of the company. “A refrigerant leak caught in May costs a fraction of what a compressor replacement costs in August.” Compressor failure can cost between $1,500 and $2,500 to repair, while early intervention typically costs between $150 and $500.
For homeowners considering system upgrades, heat pump installation offers a long-term efficiency advantage. Heat pumps move heat rather than generate it, delivering two to three times more energy output per unit of electricity consumed compared to conventional systems. In Alabama’s mild winters and long summers, a single heat pump handles both heating and cooling, reducing the need for separate systems. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for qualifying heat pump installations, lowering the upfront cost.
