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.

What is the 3-minute rule for AC?

The "3-minute rule" primarily pertains to air conditioning systems, suggesting a brief pause between cycles to protect the compressor. While not directly applicable to furnaces, it highlights the importance of proper HVAC operation. If your furnace is experiencing unusual cycling or performance issues, it's advisable to contact a professional for an assessment.

This principle often extends to furnaces. The pros can help you determine if a repair is a wise investment versus the long-term benefits of a new, efficient system for your Baltimore home.
