Professional HVAC Services Medfield

Consistent Comfort, Lower Energy Bills

When your HVAC system runs efficiently, you notice the difference immediately. Your home stays the temperature you set it to, room to room, season after season. No more cranking the thermostat up because half your house feels cold, or dealing with that one bedroom that’s always too hot.

You’ll see it on your energy bills too. A properly maintained system doesn’t have to work as hard, which means it uses less energy to keep you comfortable. Most homeowners are surprised by how much they save once their system is running the way it should.

The real benefit is knowing your system won’t quit on you when you need it most. No more worrying about whether your heat will work during a February cold snap, or if your AC will handle the next heat wave.

Dempsey Energy offers 24/7 emergency service for urgent HVAC problems. During business hours, we can often provide same-day service for emergency calls. After hours and on weekends, we prioritize calls based on urgency – if your heat goes out in winter or your AC fails during a heat wave, we’ll get to you as quickly as possible. Most emergency calls in the Medfield area receive response within a few hours, and we always let you know exactly when to expect the technician.
First, check your thermostat to make sure it’s set to heat mode and the temperature is set higher than the current room temperature. Check your circuit breaker to see if it’s tripped, and make sure your furnace filter isn’t completely clogged. If these basics don’t solve the problem, it’s time to call a professional. Common causes include faulty thermostats, ignition problems, or issues with the blower motor. Our technicians can diagnose the exact problem and get your heat working again quickly, often on the same day you call.
This usually indicates a problem with your air conditioning system while the blower fan continues to run. Common causes include a tripped circuit breaker for the outdoor unit, a dirty air filter restricting airflow, low refrigerant levels, or a malfunctioning compressor. Sometimes it’s as simple as a thermostat setting issue, but often it requires professional diagnosis. The key is getting it checked quickly – running the system when it’s not cooling properly can cause additional damage and higher repair costs.
Most HVAC systems should be serviced twice a year – once before the heating season and once before cooling season. This is especially important in Medfield due to the extreme seasonal temperature changes that put extra stress on your system. Regular maintenance catches small problems before they become expensive repairs, keeps your system running efficiently, and extends its lifespan. Our Comfort Club membership includes scheduled maintenance visits, so you don’t have to remember to call – we’ll contact you when it’s time for service.
A comprehensive maintenance visit includes cleaning or replacing your air filter, checking and cleaning the blower components, inspecting electrical connections, testing thermostat operation, and examining the heat exchanger or evaporator coils for problems. For heating systems, we’ll check the ignition system and gas connections. For cooling systems, we’ll check refrigerant levels and clean the outdoor unit. The technician will also test system operation and let you know if they spot any developing issues that need attention.
Generally, if your system is less than 10 years old and the repair cost is less than half the cost of replacement, repair makes sense. However, if you’re facing frequent repairs, your energy bills keep climbing, or your system can’t maintain comfortable temperatures, replacement might be more cost-effective. Age is a factor too – systems over 15 years old often benefit from replacement due to improved efficiency in newer models. Our technicians will give you honest advice about whether repair or replacement makes the most financial sense for your situation.
