Testimonials

The difference in our house is amazing. There used to be an odor we couldn’t figure out. After the insulation was taken out and the attics were sealed the odor went away. So did the dust and silverfish. Our house had an at least 8 degree difference between the first and second floor in temperature. They are now equal in temperature. The furnace and air conditioner have been working less. The new whole house attic fan is a wonderful addition, as it is very quiet and strong. We’ve used it a lot. All of our bathroom exhaust fans and the whole house fan is hooked up properly, so it’s all venting outside. Before it was just going into the attic. Everyone that came to our house was very nice and did an awesome job. We are very happy with a good job done. Thank you.

I want to give a shoutout to Mark Inman of Greenmark Home Performance. Mark recently helped us through some energy efficiency and aesthetic improvements to our 40-year old house. The changes made in the HVAC system and in added insulation and sealing have resulted in far lower energy bills and a much more comfortable home. The aesthetic changes have greatly enhanced the curb appeal of our home evidenced from the favorable comments of our family, friends and neighbors. Mark has very solid advice for improving energy efficiency and keen eye for design. The workers were all top-rate. We feel comfortable recommending Mark to anyone looking for help with their home improvement projects.

This past summer GreenMark upgraded our home for energy savings. We have 2 HVAC units, one for each floor. During the summer, we normally set the upstairs to 80 degrees during the day and the AC turns on about noon time. Now after GreenMark did their upgrade, the outside temperature needs to be over 95 for the AC to kick on late in the afternoon. In the past when the nights get down to the 50’s or 60’s we would open the windows, then we would close them when in the morning when it starts warming up. The AC normally is not turn on until middle of the afternoon on the first floor. Now after GreenMark did their upgrade, we have to leave the windows open in the morning so the house can warm up and not be 10 to 15 degrees colder than outside. Our perceived energy savings has been amazing. We are waiting a few more months to check out our gas and electric bills. Mark worked with us to plan all the work. The crews showed as planned. They were very friendly and respectful. The work areas were cleaner when they left than when they started. It was an all-around great experience.

Mark Inman knows what he’s doing. Before the work was done on our house, on a warm/hot day the 2nd floor was uncomfortably hot, the ground floor was cold and the basement was freezing. Yesterday (July 9, 2017) the high was 97 degrees and the house was comfortable throughout (with A/C on) with very little temperature difference between floors, including the basement. Last night the 2nd floor sleeping temperature was perfect and the rest of the house was normal. Prior to the work we would have had the A/C and ceiling fans blasting all night to control the bedroom temperature and in the morning the kitchen would have been like an icebox! Fairly expensive but money well spent. Thank you Mark!

Mark visited our office and was very informative about options we have on how to improve the air quality in the office. I was so impressed with his knowledge and ability to effectively communicate how the hvac system is intergrated with other variables that make up quality of air we breathe.

We were very happy with Greenmark Home Performance. The door was exactly what we were looking for.

We will likely be calling them for future projects.

We had Greenmark Home Performance come out for a door. We were very satisfied with the company and the product. If we had any questions or concerns, Mark was quick to respond and answered them promptly. We really liked the fact when Mark came out, he did exactly what we asked him to do, didn’t try to sell us anything we didn’t want or need. He was very professional, informative and courteous. If we decide to do any other projects, we will definitely be giving them a call to come back out. We are a satisfied customer!

We had the representative come out for an Energy Assessment. We found that he was very informative, professional and not high pressure. He explained in great detail about the program and helped us with any questions or concerns that we may have had. His experience and understanding made us feel comfortable with the program and the company. He made it very personable with us and helped us a great deal. We are very happy with the final results and when we are looking to do some other types of work, Greenmark Home Performance will be first on the list.
