How quickly can you respond to an AC emergency in Hanover?

Response times depend on the season and current service demand, but emergency AC calls get priority scheduling, especially during heat waves. During peak summer months, most emergency calls in the Hanover area receive same-day or next-day service. We maintain service availability seven days a week because AC emergencies don’t wait for convenient times. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if anything changes. The goal is getting your cooling restored as quickly as possible while verifying the repair is done correctly.

What's included in regular AC maintenance service?

A complete AC maintenance visit includes cleaning the condenser coils, checking refrigerant levels, inspecting electrical connections, testing system controls, and replacing the air filter. Our technician also examines the ductwork for leaks, lubricates moving parts, and tests the thermostat calibration. You receive a detailed report of the system’s condition and recommendations for any issues that need attention. Regular maintenance typically catches small problems before they become expensive repairs and helps your system run more efficiently. Most maintenance visits take about an hour and should be done annually before the cooling season starts.

How do I know if I need AC repair or complete replacement?

Several factors determine whether repair or replacement makes more sense. If your system is over 10–12 years old and needs frequent repairs, replacing it often saves you money long-term. Systems that can’t maintain comfortable temperatures, produce unusual noises, or cause high energy bills may need replacement. However, newer systems with isolated problems usually benefit from professional repair. Our qualified technicians can assess your system’s overall condition, explain your options clearly, and help you make the decision that makes the most financial sense. The key is getting an honest evaluation from someone who won’t push unnecessary replacement.

Why is my AC running constantly but not cooling properly?

Several issues can cause this frustrating problem. Low refrigerant levels from a leak prevent proper cooling while forcing the system to run continuously. Dirty condenser coils can’t release heat effectively, making the system work harder without achieving proper cooling. A failing compressor may run but not circulate refrigerant properly. Ductwork leaks allow cooled air to escape before reaching your living spaces. Sometimes the issue is as simple as a clogged air filter restricting airflow. Professional diagnosis identifies the root cause quickly, preventing you from wasting energy and money while remaining uncomfortable.

What size AC system do I need for my Hanover home?

Proper AC sizing depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate conditions. Massachusetts humidity levels affect sizing calculations significantly. An oversized system cycles on and off frequently, wasting energy and failing to remove humidity properly. An undersized system runs constantly and can’t maintain comfortable temperatures during peak summer heat. Professional load calculations consider all these factors to determine the right capacity for your specific home. The outcome confirms optimal efficiency, comfort, and equipment longevity while avoiding the problems that come with incorrectly sized systems.

How can I lower my air conditioning costs this summer?

Several strategies reduce AC costs without sacrificing comfort. Set your thermostat to 78°F when home and higher when away—each degree higher saves about 3% on cooling costs. Replace air filters monthly during peak season to maintain proper airflow. Use ceiling fans to circulate air, allowing you to set the thermostat higher while staying comfortable. Close blinds during the day to block heat from windows. Schedule annual maintenance to keep your system running efficiently. Seal air leaks around windows and doors to prevent cooled air from escaping. Consider a programmable thermostat to avoid cooling an empty house.
