We have a commercial building that we struggle to keep a constant temp in. We currently have 4 15 ton split systems, ran through a Jace controller. We have a large heat load and during the summer months we see a 6 to 7 deg temp swing in a 10 hour period. We are looking for options that would bring us down to a 2 deg swing in 24 hour period.

We will be building a home in Mooresville within the next 2 years. We just bought property. We have been interested in the benefits of geothermal energy. I'm interested in estimated cost, etc. The best time for me to speak to someone is between 4-5pm Thank you.

Need to weather proof new home. Construction was completed this year but windows doors are not weather tight. I have many large windows and I suspect many of them need resealing. One leaks when it rains. Garage door is also not weather proof. I can see light rays when it's closed and insects have been finding their way in. Can also see small space at door corner when back door is completely shut.

I believe our attic is poorly insulated - to the point where our upstairs dedicated HVAC cannot keep it cool (the HVAC was recently serviced, and is in good working condition). We would like to get an evaluation and estimate. Thank you!!

My craw space is tore underneath. Could you please tell me how much will it cost to replace the whole thing? Is it free for them to come out here to do a estimate? Thank you

This home is new construction - we are under contract to purchase this home and wanted an estimate on crawl space sealing. It has engineered bamboo floors installed and they have started to "cup" on the first floor. The humidity seems to be high in the crawl space and could be attributing to the floor issues. There is a vapor barrier and crawl space vents with a wooden door to access the crawl space. The air handler down there seems to have an unusual amount of condensation for a crawl space unit. We have friend in Brevard, NC that own a business sealing crawl spaces and they highly recommend we get it looked at. Thank you - Brian

I have a two story home and for years the bedroom that leads to the attic is always very hot or very cold depending upon the time of year. I am looking to fix this and all the reading I have done suggests I need to upgrade the insulation in my attic. Because of this, I am looking to receive a quote to either upgrade or replace my attic insulation.
