Work Requests From Coraopolis, PA
Project Location: Coraopolis, PA
I'd like to obtain a quote for AC unit purchase and install vs heat pump purchase and install
Project Location: Coraopolis, PA
My upstairs Cape Cod Dormer is 15-20 degrees hotter than downstairs. I have a newly updated ac unit, but after gaining access to my attic (I'm new to owning the home) I see there seems to be no/incorrectly installed insulation. I can feel the heat building up behind the knee wall and sloped ceiling. Not sure if this is the issue or a combination of other issues. Would love to get an evaluation.

A/C just runs & runs and can't keep house cool if temp gets over 83-84 degrees. On 90 degree days it can get to 80 degrees upstairs. My neighbors have said the unit is too small and they had same problem but a larger unit too care if problem. I'd like a free estimate on upgrading. Thanks.

I'd like to get an estimate for a heated driveway system. I have a house under construction at this time so I'd like to get a quote before the driveway is set to be laid. I'd like to find out how much it will cost for the rough in portion with just the pipes, and then for the full system. That way I can decide if I want to just prep the driveway to add the boiler later, or if I can just do the whole system now.

Replacing furance and air-conditioning both upstairs and downstairs
Project Location: Coraopolis, PA
Hello, I'm planning to replace my entire heating-cooling system in the next few months. I currently have a Bryant 80% furnace, 44,000 BTU / hr, 14 inch wide and looking for something similar to this. Outside A/C unit is a Trane XE1000. Also, if you install water heaters and it can be replaced at the same time, I can send you details about my existing, gas based water heater. Please let me know the price for the new system. Thank you, Dean

I currently would like someone to come look at my duct work. Our house is unevenly heated and we also have have some loose fitting areas where air comes into our basement, we also have a hole in one duct.
Project Location: Coraopolis, PA
The home was build in the late 1980's, the heat and cooling distribution in the home is very uneven with concerns around the 2nd floor. Looking at the insulation we've seen in crawlspaces and on the walls when we did some remodels shows less then optimal insulation.

I have a Weil-McLain PD9, series 1 gas boiler. It has a White-Rodgers 25G53 control valve connected to a 30A48-5 automatic pilot. this feeds my homes baseboard hydronic heating. The automatic pilot has stopped functioning and apparently, is no longer made. I need to replace the Boiler ASAP. I am currently using space heaters, and manually lighting the boiler for 30-45 minute increments when home. The heating area of the house is roughly 2300 SqFt. We would need to finance if you have any options for that, as we were not planning to replace this until next summer.
