I had called out another AC company as my tenants complained they were not getting any warm air blowing out this past winter, the air was cool. The other company said I needed a whole new outside heat pump and it would cost me $2600. I wanted a second opinion and called Extreme Comfort.
They sent tech Howard out and he said the only issue were two loose wires in the inside unit and that everything in the outside unit was fine. He only charged me for the service call to tighten the wires. I appreciate Howard's honesty as he kept me from getting scammed by this other company whose name I won't mention in this post.
