"The project was to install a zone system for my upper and lower floor, I have a large house and cooling and heating it was always a problem, the second floor was always to hot in the summer and cold in the winter. The AC and furnace was working none stop and the result was crazy electric bill. I called 2 other AC technicians before Climate Construction to get estimates, after talking to both of them I felt that I am getting ripped off. one told me that I need to change the AC and furnace unit to get results and the other said the I need to replace bunch of duct work or the zoning will not work. Than I called Climate Construction , Roman came in and quoted me with a very very reasonable price, the AC didn't had to be changed and nor the furnace, I was surprisingly amazed! The job was completed FAST and guess what, everything worked like a CHARM! I set the schedule of the thermostat for the lower floor during the day and upper floor during the night! The result are UNBELIVABLE! GET YOUR SELF A ZONING SYSTEM!! and be carful not to get ripped off!"

I was very grateful that he was able to come out so quickly and fixed the problem. Very nice serviceman. I highly recommend him!"

They showed up on time, stayed until the job was completely finished, and made sure everything was cleaned up before they left. Super friendly, professional, and hardworking. I highly recommend them!"
