Everything Your AC System Needs

Emergency repairs when your system breaks down unexpectedly. Routine maintenance to prevent problems and keep efficiency high. New installations when it’s time to replace an old, unreliable unit.

We service all major brands and handle both central air systems and ductless mini-splits. Maintenance includes cleaning coils, checking refrigerant levels, testing electrical connections, and replacing filters. Installations come with proper sizing calculations to ensure your new system handles your home’s cooling needs without wasting energy.

The Dempsey Comfort Club membership gives you priority scheduling, maintenance reminders, and member benefits. It’s designed for homeowners who want to stay ahead of AC problems rather than deal with emergency breakdowns during peak summer heat.

How often should I have my air conditioning system serviced?

Most AC systems need professional maintenance once a year, ideally in late spring before the heavy cooling season begins. Annual tune-ups catch small problems before they become expensive repairs and keep your system running efficiently. If you have an older system or one that runs heavily during summer, you might benefit from twice-yearly service. Regular maintenance typically extends equipment life by several years and reduces energy costs by keeping the system clean and properly calibrated.

What are the signs that my AC needs immediate repair?

Call for service if your AC stops cooling, makes unusual noises, or produces warm air instead of cold. Other warning signs include frequent cycling on and off, unusually high energy bills, or moisture/water pooling around the unit. Strange smells, especially burning odors, require immediate attention. If your system struggles to maintain temperature or takes much longer to cool your home than usual, that indicates a problem that will likely get worse without professional repair.

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

Consider replacement if your system is over 12-15 years old and needs frequent repairs, especially if repair costs exceed half the price of a new unit. Rising energy bills, inconsistent cooling, and the need for constant thermostat adjustments often signal it’s time for new equipment. However, newer systems with isolated problems usually benefit from repair rather than replacement. A qualified technician can assess your specific situation and help you make the most cost-effective decision based on your system’s condition and repair history.

Why is my air conditioning system freezing up?

AC systems freeze when airflow is restricted or refrigerant levels are incorrect. The most common cause is a dirty air filter that blocks airflow over the evaporator coil, causing it to get too cold and freeze. Other causes include blocked vents, dirty coils, low refrigerant due to leaks, or blower fan problems. If your system freezes, turn it off and let it thaw completely before restarting. Check and replace the air filter, but call for professional service to identify and fix the underlying cause.

How can I reduce my air conditioning costs this summer?

Start with regular filter changes every 1-3 months during cooling season to maintain proper airflow. Set your thermostat to 78°F when home and higher when away – each degree lower increases energy use significantly. Use ceiling fans to circulate air and make higher temperatures feel comfortable. Keep blinds closed during peak sun hours and ensure vents aren’t blocked by furniture. Annual professional maintenance keeps your system running efficiently, and sealing air leaks around windows and doors prevents cool air from escaping.

Do you provide emergency air conditioning service in Needham?

Yes, we provide emergency AC service for urgent situations when your system fails during extreme heat or poses safety concerns. Emergency calls are prioritized, especially for customers with health conditions, young children, or elderly family members who are vulnerable to heat. While emergency service may include additional fees for after-hours calls, we work to restore your cooling as quickly as possible. For non-emergency issues, same-day or next-day service is usually available and more cost-effective than emergency rates.
