I bought a home this Summer in Southeast TX that needed a lot. One of which was a new heating/cooling system. I had three companies come in and price me traditional air systems. The company I liked the best gave me a price of $7600. That was for everything, new inside and outside unit and all new ducting. I was pretty happy with that price. Then my mind got to thinking about a show I had seen years ago about Geo (ground source heat pump). I thought I would check it out before I committed to the traditional system. I got 3 companies to give me an estimate. All were for a closed loop system since I had the acreage. One was for 25-28k. Too high for my liking. One was for 22-25k. Still too high to justify the cost. The third was for $14,700. I was stunned but intrigued by this price. I decided to meet a second time with this man to ask more questions and nail down where he would lay out the loop. As we met that Saturday morning the first question I asked was how come his price was so much lower than the other quotes I had received. He said that some companies were ripping people off. It did not have to cost that much. His statement was that I needed new ducting and the inside blower either way. Yes the inside units were different, but the work is about the same. He said the only big difference in the installation was the geo needed the trenches dug and the loop field laid. He said that he paid about $600 per day for a digger and that it would take less than two days. After that the loop was easy to lay down. He said at his quoted price he made a reasonable profit. It made sense. I had already done investigation on this company and they had good reviews out there on the web. What he said next brought me to the tipping point. He said “You don’t pay me anything until the system is up and running and the cool air has cooled off your house. You can see it works.” That gave me some comfort so I asked for references and they were outstanding references. Of course they would be coming from him, but that combined with my digging (BBB, Angie’s List, Yelp…) had me about to jump. When I did the math I was convinced. $14700 - $4400 (30% tax credit) = $10300 - Geo System complete install, everything including all new ducts $7600 - Conventional system complete install, everything including all new ducts. $2700 – The difference between conventional and Geo. The difference between the two systems was 2700. I was convinced. The system went in the last week of Aug 2013. It has now been running for 1.5 months. I received my first electric bill (whole house is electric) which was for September. It was $79. 00 During the month of September it was stifling hot here in southern tx. During the beginning of the month I had contractors working on other issues in the home including all new windows and doors. The reason I say that is that at various times during the hot month the doors and windows were open for hours at a time and ins some cases 7-8 hours. The $79.00 electric bill floored me how small it was. Had the new windows been in and the new exterior doors been in I can only imagine that bill shrinking even further. The system installed is a 3 ton Bosch SM Series 2 Speed heat pump with hot water generator kit. Overall the experience has been a good one. I cannot say there were not issues, there were but they were all resolved. My yard still looks beat up, but I know time will fix the damage caused by the trenches. The cooling has been tremendous. It still amazes me when I walk into the cool comfortable house and the even cooling hits me. I know the science behind it, but it still amazes me. I have not turned on the heat other than to test it at this point. I do look forward to a warm inexpensive first Winter with my new system. If you are in southern tx and want a reference to the company I used, drop me a line. They do work all over the area.
