Attic or Whole House Fan Installation
I can’t begin to express how great the entire experience was from the estimate to the finished installation! Stuart is very professional. On time. Knowledgeable. Clean. Detailed. Highly recommend! He installed an attic fan. I will have him back to add insulation in my attic soon! Pricing is more than fair! I had other bids, they didn’t compare to Green Star Energy! For all that was done, it should have been the highest bid but it wasn’t. If you are looking for a company to install an attic fan or any insulation, ventilation work, you will not regret choosing this company. I should have taken more pictures! He had drop cloths from the front door down the hall to the end of the work area. He cleaned as he worked so there was never a mess. Very little dust at any given time I looked. When he finished, my house looked just like it did before he arrived plus a new fan! If I could give more than 5 stars I would! ⭐️ ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ 10/10 - I recommend

Stuart was great! Other companies quoted me for thousands more and he was able to come in and just fix the problem instead of trying to scam me into a sale.

After getting bids from several different contractors, we went with Green Star Energy. Stuart, the owner, has a wealth of practical knowledge due to his many years of experience in home construction, remodeling, and insulation. Stuart's experience was important because after thoroughly inspecting our attic, he sold us only what he considered necessary to bring us up to the R-49 insulation we wanted. Perhaps most appreciated was Stuart's professionalism. He was on time for the inspection and sent a detailed bid within 24 hours. He answered all of our questions with a knowledge that reflected his years of experience. From first phone contact to completed job took only five days. He did exactly what was outlined in his bid and cleaned up completely after finishing the job. Lastly, Green Star Energy had the lowest bid of any other contractors we met with.. In one case, it was several thousand dollars less.

Very professional. That is hard to find these days. Scheduled a meeting for a bid and was on time and prepared. Gave a fair priced bid and followed up by meeting the exact schedule and expectations for the completed job.

Stuart is very knowledgeable and efficient. He replaced my whole house attic fan with additional suggestions for energy efficiency. I didn't have to wait forever to schedule the installation either. The process was explained. Which I appreciate. I am thoroughly pleased and satisfied with his work and service!

I was very impressed with the work I had done and the price of the work I had done. Stuart came and took pictures of my attic and measured insulation I had in the attic. Told me how much insulation he suggested to blow in. When finished he had pics of finished product. He even sealed around electrical boxes, lights, bathroom fans and vent pipes. Very well done! ð ð ð
