HVAC Company Dover MA

Complete Heating and Cooling Services

Dempsey Energy handles everything from emergency repairs when your system quits to planned installations and regular maintenance. We work on all major HVAC brands and know the specific challenges of heating and cooling homes in Dover’s climate.

Emergency service is available when your heating fails during a snowstorm or your AC gives out during a heat wave. For planned work, we’ll coordinate installation around your schedule and make sure your home stays comfortable during the process.

Our maintenance programs catch small issues before they become expensive problems. Regular tune-ups keep your system running efficiently and help you avoid those middle-of-the-night emergency calls. Dover homeowners especially benefit from pre-winter heating checks and spring AC preparation.

How quickly can you respond to HVAC emergencies in Dover?

Emergency response times depend on the severity of the situation and current service demand, but we prioritize calls where customers have no heat during winter or no cooling during extreme heat. We maintain emergency service availability and dispatch technicians as quickly as possible. Dempsey Comfort Club members receive priority scheduling for both emergency and routine service calls. For non-emergency situations, we typically schedule service within 24-48 hours depending on availability.

What should I do if my heating system won't turn on?

First, check your thermostat settings and make sure it’s calling for heat. Verify the circuit breaker hasn’t tripped and replace the air filter if it’s extremely dirty, as a clogged filter can cause safety shutoffs. Check that your outdoor unit isn’t blocked by snow or debris. If these basic steps don’t solve the problem, it’s time to call for professional diagnosis. Attempting repairs beyond these simple checks can be dangerous and may void warranties. Modern heating systems have multiple safety features that require proper training to diagnose and repair safely.

How often should I schedule HVAC maintenance in Massachusetts?

Massachusetts climate demands twice-yearly maintenance – heating system service in fall before winter arrives, and cooling system service in spring before summer heat. This schedule catches potential problems before peak usage seasons when you need your system most. Regular maintenance includes cleaning, lubrication, safety checks, and efficiency testing. Skipping maintenance often leads to higher energy bills, shorter equipment life, and inconvenient breakdowns during extreme weather. Well-maintained systems typically last 15-20 years versus 8-12 years for neglected equipment.

Why is my HVAC system blowing hot air when it should be cooling?

Several issues can cause this problem. Low refrigerant levels from leaks prevent proper cooling, while dirty air filters restrict airflow and can cause the system to overheat. Thermostat problems might send wrong signals to your equipment. Outdoor unit issues like dirty coils or failed components also cause cooling problems. Some systems have reversing valves that can malfunction and switch to heating mode accidentally. Professional diagnosis is essential because refrigerant work requires EPA certification and specialized equipment. Attempting DIY repairs on cooling systems often makes problems worse and more expensive.

What's included in your Dempsey Comfort Club membership?

The Dempsey Comfort Club provides priority scheduling for both routine maintenance and emergency service calls. Members receive regular system tune-ups designed to prevent problems and maintain efficiency. The program includes systematic follow-up to ensure customer satisfaction and catch any developing issues early. Membership benefits are structured to give customers peace of mind and help avoid costly emergency repairs through preventive maintenance.

Do you service all HVAC brands and system types?

We service all major HVAC brands including both traditional and high-efficiency systems. Our technicians are trained on various equipment types from basic furnaces and central air to heat pumps, ductless systems, and hybrid heating solutions. We handle both residential heating and cooling equipment regardless of age or manufacturer. However, very old or obsolete systems may have parts availability challenges, which we’ll discuss honestly during diagnosis. Our experience with Dover’s mix of older homes and newer construction means we understand the unique requirements of different system types and home configurations.
