Very professional company. Our old system was over 20 yrs old and was costing a fortune to cool the house in the summer. Hamstra did a lot of measurements and tests of the house and system and recommended a Lennox system with an electrostatic filter. They told us in advance what would be happening and when it would be done, and the work went exactly as we were informed it would. All of the service technicians were very nice and appeared to be very knowledgeable. We've been running the new system for about 2 weeks, and the difference is like night and day. There is almost no noise from the furnace fans or the outside AC unit. The house's cooling is much more even, room to room. I haven't got an electric bill yet, but I expect to be very happy with that too. I was a little leery of the duct cleaning and sealing services. I didn't think it would do much of anything, but my wife insisted we do it. After the fact, I can say that I am very glad we had those services done. The dust levels in the house have gone done noticeably. We used to have to dust a couple times a week. We haven't had to dust yet since the new system went in.\r
Also, with the old system, I always had very slight allergic symptoms when the AC was running, nothing great but it was noticeable. From the first day with the new system. those symptoms disappeared. I'd now recommend those services to others in the future.\r

Overall, I am very pleased with Hamstra and would use them again in the future.\r
