How quickly can you respond to HVAC emergencies in West Wareham?

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

First, check your thermostat settings and make sure it’s set to heat mode with the temperature above your current room temperature. Check that your circuit breaker hasn’t tripped and replace your air filter if it’s dirty, as a clogged filter can cause the system to shut down for safety. If these basic steps don’t solve the problem, don’t try to force the system to start. Call us instead. Heating systems have safety mechanisms that shut them down when something’s wrong, and trying to override these can cause expensive damage or safety hazards.

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

This usually means your outdoor unit isn’t working properly while your indoor fan continues to run. Common causes include a tripped breaker to the outdoor unit, low refrigerant levels, or a failed compressor. Sometimes it’s as simple as a dirty outdoor coil that needs cleaning, but refrigerant issues require professional attention. Don’t ignore this problem, as running your system when it’s not cooling properly can cause additional damage. Turn off your system and call us for a proper diagnosis. We can usually identify the issue quickly and get your AC cooling again.

How often should I have my HVAC system serviced in Massachusetts?

We recommend annual maintenance for most systems, ideally in the spring for cooling and fall for heating. Massachusetts weather puts real demands on HVAC systems, from humid summers to freezing winters, so regular maintenance isn’t optional if you want reliable performance. During maintenance, we clean components, check refrigerant levels, test safety controls, and catch small problems before they become expensive repairs. Our Dempsey Comfort Club members get scheduled maintenance as part of their membership, which helps ensure their systems are ready for whatever weather comes next.

After repairs, we test the system to ensure it’s working properly and explain what we did and why.

No hidden fees, no surprise charges, just honest service and transparent communication.
