    We have a one-car garage attached to our home and want to turn into a livable space. I'd like to get a quote to install a mini-split system and blow insulation into walls (and probably attic, i have looked, but assuming there isn't insulation in either).

    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.

    Hello. My house resides on stilts and the cold winter air comes up through the floor. I just recently purchased this home and don't believe the insulation has been replaced in decades. I'd really love to have someone come see what can be done to help me out. Thanks

    We had a house fire 5 months ago...we replaced the entire roof... 900 sq foot ranch house made in 1965. We put in a new vaulted ceiling in the kitchen and living room... currently we have NO insulation in the attic - roof area. I would like an estimate on doing our attic and roof insulation. We are in Fort Mill, SC Thanks a lot. Ray

    We have a Trane system, and this morning the heat indicated "On" on the thermostat, but the unit wasn't running. After a couple hours, the heat did actually come on, but would like a service visit, and your company was highly recommended. I have not yet looked at the codes to see what the issue was, that's on my to-do list :) Let me know if you are available for a service visit. thanks Kerry Simpkins
  • Project Location: Fort Mill, SC
    We have a Generac 25KW installed at our former home in Chester, SC and we need to have moved to our new home in Tega Cay, SC. This would include removing it, transporting it to Tega Cay, reinstalling it and servicing the unit. The Generac is relatively new, having been installed in February 2016. Please let me know if you have do this project. Thanks
  • Project Location: Fort Mill, SC
    I'd like a quote on two projects: 1. Cleaning our air ducts (we have 15 ceiling and floor vents, and 2 return vents), from an electric heat pump that's located in our crawlspace 2. Moisture control and air sealing of crawlspace: we have a poor plastic vapor barrier and floor joint insulation, but high humidity and moisture wicking up into the concrete block foundation has led to the insulation dripping off and minor mold spots in a couple of places. I'd like to control moisture and insulate the floor/improve energy efficiency with our heat pump. I'd specifically like to know about the option for open or closed cell spray foam along the foundation walls and a new vapor barrier. I don't know that I want to encapsulate the crawlspace -- just protect the heat pump and keep the house interior tight and energy efficient. Thanks for any guidance! -- Patricia
