How quickly can you respond to an HVAC emergency in Needham?

We prioritize emergency calls, especially during extreme weather when your heating or cooling system failure affects your family’s safety and comfort. Response times depend on the current call volume and weather conditions, but we work to get a technician to you as quickly as possible. Our Dempsey Comfort Club members receive priority scheduling for both emergency and routine service calls. When you call, we’ll give you a realistic timeframe and keep you updated if anything changes.

What should I do if my HVAC system is blowing hot air instead of cold?

First, check your thermostat settings to make sure it’s set to “cool” and the temperature is lower than the current room temperature. Check that your air filter isn’t completely clogged, as this can cause the system to overheat and shut down the cooling function. If these basics don’t solve the problem, you likely have a refrigerant leak, compressor issue, or electrical problem that requires professional diagnosis. Don’t keep running the system if it’s blowing hot air, as this can cause additional damage and higher repair costs.

Why won't my heating system turn on when I adjust the thermostat?

Several issues can prevent your heating system from responding to thermostat changes. The most common causes include a dead thermostat battery, tripped circuit breaker, dirty air filter restricting airflow, or a malfunctioning thermostat. Sometimes the issue is with the furnace itself, such as a faulty ignition system or safety switch that’s preventing startup. Before calling for service, check your circuit breakers and replace the thermostat batteries if applicable. If the system still won’t respond, it’s time for professional diagnosis to avoid potential safety hazards.

How often should I schedule maintenance for my HVAC system?

Most HVAC systems need professional maintenance twice a year – once before the heating season and once before the cooling season. This timing allows us to catch potential problems before you’re relying on your system during extreme weather. Regular maintenance includes cleaning components, checking refrigerant levels, testing safety controls, and replacing filters. Needham’s climate puts extra stress on HVAC systems with our cold winters and humid summers, making consistent maintenance even more important for preventing breakdowns and maintaining efficiency.

What's included in your Dempsey Comfort Club membership?

The Dempsey Comfort Club provides priority scheduling for both routine maintenance and emergency repairs, which means you get faster service when your system needs attention. Members receive regular maintenance visits to keep their systems running efficiently and catch problems early. The program is designed for homeowners who want proactive care rather than waiting for breakdowns to happen. Membership helps you avoid emergency repair costs and extends the life of your HVAC equipment through consistent professional attention.

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

Generally, if your system is less than 10-12 years old and the repair cost is less than half the cost of replacement, repair makes sense. However, if you’re facing frequent breakdowns, dramatically higher energy bills, or major component failures on an older system, replacement often provides better long-term value. We’ll assess your current system’s condition, explain your options clearly, and help you make the decision that makes the most financial sense for your situation. Age, efficiency, and repair history all factor into this recommendation.
