Heating Contractor Green Harbor MA

Complete HVAC Solutions for Your Home

We handle everything from emergency repairs when your system fails to complete installations when you’re ready for an upgrade. Whether your heating system won’t turn on during a February cold snap or your HVAC system is blowing hot air when you need cooling, we have the experience to get it fixed.

Our service includes thorough system diagnostics, repair or replacement of faulty components, and testing to ensure everything works properly. We also offer preventive maintenance through our Dempsey Comfort Club to catch small problems before they become expensive emergencies.

Green Harbor’s coastal location means your HVAC system works harder than systems inland. Salt air, humidity, and temperature swings all take their toll. We know how these conditions affect different system components and what to watch for during maintenance visits.

Why is my HVAC system blowing hot air when I need cooling?

This usually happens because of a refrigerant leak, a faulty reversing valve, or electrical issues with your system’s controls. In Green Harbor’s humid climate, frozen evaporator coils can also cause this problem. The system tries to cool but can’t complete the refrigeration cycle properly. Our technicians start by checking refrigerant levels and testing the electrical components that control your system’s cooling mode. Most of these issues can be repaired the same day, though refrigerant leaks require finding and sealing the leak before recharging the system.

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

First, check your thermostat settings and replace the batteries if it’s battery-powered. Make sure your circuit breaker hasn’t tripped and that your furnace switch is in the “on” position. If these basics don’t solve it, you likely have a more serious issue like a faulty ignition system, gas supply problem, or safety control that’s preventing startup. Don’t attempt to repair gas heating systems yourself – call us for safe, professional diagnosis. We can usually diagnose and repair most heating system problems the same day, getting your heat restored quickly.

How often should I have my HVAC system serviced?

Most manufacturers recommend annual maintenance, but in Green Harbor’s coastal environment, we suggest twice-yearly service – once before heating season and once before cooling season. Salt air accelerates corrosion on outdoor units, and the humidity affects indoor components too. Regular maintenance catches small problems before they cause system failures. Our Dempsey Comfort Club members get priority scheduling for maintenance visits and discounts on repairs. Proper maintenance typically extends system life by 3-5 years and keeps your energy bills lower by maintaining peak efficiency.

How do I know if I need HVAC repair or full system replacement?

Age is the biggest factor – systems over 15 years old with major component failures often make more financial sense to replace. If your repair costs are more than half the price of a new system, replacement usually makes sense. Also consider your energy bills – if they’ve been climbing steadily, a new efficient system might pay for itself in energy savings. We’ll give you honest recommendations based on your system’s condition and your budget. Sometimes a good repair buys you several more years, and sometimes replacement is the smarter long-term investment.

Do you provide emergency HVAC service in Green Harbor?

Yes, we provide emergency service for urgent heating and cooling problems. We understand that HVAC failures don’t wait for convenient times – they happen during heat waves, cold snaps, and weekends when you need your system most. Our emergency service prioritizes safety issues like gas leaks or electrical problems, and comfort emergencies like complete system failures during extreme weather. We carry common repair parts and have the experience to diagnose problems quickly, so most emergency calls can be resolved the same day.

What makes Dempsey Energy different from other HVAC contractors?

Our customer database includes over 12,000 local homeowners who trust us for their comfort needs. We offer the Dempsey Comfort Club for customers who want priority service and maintenance benefits.
