How quickly can you respond to emergency HVAC calls in Westwood?

Response times vary based on current service volume and weather conditions, but we prioritize emergency calls and work to reach you as quickly as possible. Our Dempsey Comfort Club members receive priority scheduling for both emergency and routine service calls. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if anything changes.

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 set higher than the current room temperature. Check your circuit breaker to ensure power is reaching the system. Look at your air filter – a completely clogged filter can cause some systems to shut down as a safety measure. If these basic checks don’t solve the problem, you likely have a more serious issue that requires professional diagnosis. Don’t attempt to force the system to start or bypass safety features, as this can cause additional damage.

Why is my HVAC system blowing hot air instead of cold?

Several issues can cause this problem. Your thermostat might be set incorrectly or malfunctioning. The outdoor unit could be dirty or blocked, preventing proper heat exchange. Low refrigerant levels, often caused by leaks, can prevent the system from cooling properly. A faulty reversing valve in heat pump systems can cause the unit to stay in heating mode. Electrical issues or a failing compressor can also cause cooling problems. This issue requires professional diagnosis because the causes range from simple fixes to major component failures.

How often should I schedule HVAC maintenance in Massachusetts?

We recommend annual maintenance for most systems, ideally in the fall before heating season begins. However, if you have both heating and cooling systems or a heat pump that works year-round, twice-yearly service provides better protection. Massachusetts weather puts significant demands on HVAC systems with cold winters and humid summers. Regular maintenance catches problems early, keeps your system running efficiently, and helps prevent breakdowns during extreme weather when you need your system most. Our Dempsey Comfort Club makes this easy with scheduled maintenance reminders.

What's included in your HVAC maintenance service?

Our maintenance service includes thorough inspection of all system components, cleaning of key parts like coils and filters, checking refrigerant levels, testing electrical connections, calibrating thermostat operation, and examining ductwork for leaks or damage. We also test safety controls, lubricate moving parts, and check for proper airflow throughout your system. You receive a detailed report of our findings and recommendations for any issues we discover. This comprehensive approach helps prevent unexpected breakdowns and keeps your system running efficiently, which saves money on energy costs.

Do you provide estimates for HVAC system replacement?

Yes, we provide detailed estimates for system replacements that include equipment costs, installation labor, and any necessary modifications to existing ductwork or electrical systems. Our estimates are comprehensive and transparent – no hidden fees or surprise charges later. We’ll assess your home’s specific heating and cooling needs, discuss energy efficiency options, and explain the benefits of different system types. We take time to ensure you understand your options and the long-term value of each choice before making any recommendations.
