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 for AC advises against rapidly cycling your air conditioner on and off. This practice can put undue stress on the compressor, a critical component of your system. Allowing the system to complete its cooling cycle helps it operate more efficiently and can extend its lifespan, which is important for Baltimore's climate.
