What affects the price

HVAC repair costs change based on a few main things. The age and brand of your unit play a big role, as older systems sometimes need parts that are harder to source. The nature of the problem is the biggest factor—a simple capacitor swap is much cheaper than addressing a refrigerant leak or a failed compressor motor. Labor time also depends on how easily a technician can access your equipment in a tight attic or crawlspace. We provide exact pricing confirmed free on the call.

Frequently asked in Boston

Why is my furnace running but not heating?

This can happen for several reasons, from a dirty air filter to a malfunctioning thermostat or a problem with the ignitor. If your furnace is cycling on but not producing warm air, it's best to have a licensed pro take a look. They can diagnose the specific issue and explain what's needed to get your heat back up and running in your Boston home.

What does a typical furnace repair cost?

What is the 3-minute rule for AC?

The "3-minute rule" typically refers to allowing your AC system to rest for at least three minutes between cycles to prevent compressor damage. While this is more relevant to air conditioning, it highlights the importance of not overworking your HVAC system. For furnaces, consistent issues might indicate a deeper problem that requires professional attention.

This rule can also apply to furnaces. The pros can help you evaluate if a repair is a worthwhile investment versus the long-term benefits of a new, energy-efficient system for your Boston residence.
