We offer 24/7 emergency service for urgent heating and cooling failures. Response time depends on the severity of the situation and current service volume, but we prioritize calls where people have no heat in winter or no cooling during extreme heat. Dempsey Comfort Club members get priority scheduling, which means faster response times during peak demand periods. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if anything changes.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature set higher than the current room temperature. Check your circuit breaker to see if it’s tripped, and make sure your furnace switch is in the on position. If you have a gas furnace, verify that the pilot light is lit. Replace your air filter if it’s dirty, as a clogged filter can cause the system to shut down. If none of these steps work, call us for service rather than trying to troubleshoot further – heating systems have safety mechanisms that shut them down when something’s wrong.
This usually happens when your outdoor unit isn’t running properly, your refrigerant is low, or your system has a mechanical failure. Check to make sure your outdoor unit is getting power and the fan is spinning when your AC is running. A dirty air filter can also cause this problem by restricting airflow and causing the system to overheat. Low refrigerant typically means you have a leak that needs professional repair – adding refrigerant without fixing the leak won’t solve the problem long-term. This type of issue requires professional diagnosis to determine whether it’s a simple fix or a more complex repair.
Most systems need professional maintenance twice per year – once before heating season and once before cooling season. New England’s climate puts extra stress on HVAC equipment with cold winters and humid summers, so regular maintenance is especially important here. During maintenance visits, we clean components, check refrigerant levels, test safety controls, and identify potential problems before they cause breakdowns. Our Dempsey Comfort Club includes scheduled maintenance visits, so you don’t have to remember to call – we’ll contact you when it’s time for service.
If your system is less than 10 years old and the repair cost is less than half the price of replacement, repair usually makes sense. For older systems, especially those needing expensive repairs like compressor or heat exchanger replacement, replacement often provides better long-term value. We’ll assess your system’s age, condition, and efficiency, then give you honest recommendations about repair versus replacement. Factors like rising energy bills, frequent breakdowns, and uneven heating or cooling in your home all point toward replacement being the smarter choice.
Yes, we provide upfront pricing before beginning any work. Our technician will diagnose the problem, explain what needs to be done, and give you a clear estimate for the repair or installation. You’ll know exactly what you’re paying before we start, with no hidden fees or surprise charges. For larger projects like system replacement, we’ll provide a detailed written estimate that breaks down equipment and labor costs. We believe you should have all the information you need to make an informed decision about your HVAC investment.
