We try to look at every home when possible to give customers an idea of what will be involved with their system. But, because we do so many systems sometimes we end up just going to a home and installing the system, especially on Real Estate deals. The agents that use/recommend us know we will do a good job and be honest about what we did. Yesterday we arrived at a home to put a system in that we did not yet see. I ask as many questions as possible to determine what we are getting into, especially if its a fast sale and closing. This particular home had many open holes with exposed earth, and exposed drains. I had to tell the seller and his agent that a system could not be installed because of the condition of the slab. I explained that some other work would need to be completed before we could install a system. We can use foam here and there, but this home needed some major concrete work and a plumber. A system installed at this home could create a dangerous environment for the new owner. You don’t want to pull air from under the slab and in turn open holes through the slab and open drains. Carbon Monoxide can kill someone if you pull enough air from a home and back draft combustible appliances, such as a water heater. Plus the amount of conditioned air that would be lost would be tremendous in turn raising the cost of heating/cooling the home. I was told they would find another company that was willing to put in a system. Any comments?
