Our heat went out Saturday evening. It's an older Goodman unit - at least a dozen years old. It has a small freon leak and we've had both the AC and heat portions of our HVAC system repaired twice since we took ownership of this home 18 months ago. Interested in possible replacement.

I would like to get an estimate on a replacement whole house unit. Currently we have gas, heat pump unit that is 17 yrs old and its past time for it to be replaced. We would like to have someone that could take some time with us, answer questions, learn about the different units, find the best one for us etc Do you come out on weekends to give estimates? If we have to wait a couple of weeks for someone to come out, that will be fine. We plan on replacing within 6 months. Thank You Diane Robinson

Our air conditioner unit is not blowing cool air and the outside fan is not working at the moment. I have breathing problems and this is making weak.
Project Location: York, SC
I have two AC units (upper/lower), 9 years old. Lower is not keeping up this summer. It is keeping the house ~80-83 degrees but wont go under 79. This happens about every 2-3 years with these units. Typically need coolant, but I'd like to make sure they're clean and nothing else is wrong
