I had a problem, since I bought my house. The upstairs bedroom, especially on one side of the house, was always much colder than the downstairs in the winter, and hotter in the summer. My house is a few decades old, and based on the older building codes. The attic was insulated to a level below R-30, and possibly even R-20 as the insulation lost effectiveness over the decades.
I suspected that the attic insulation was causing these problems. After searching for a company which had excellent reviews, I found Eco Comfort. Wojtek answered the phone when I called, and was able to explain in detail what his company does. I was able to provide sizing and other details on the phone, and received an estimate immediately.
There were a few items I needed done, including properly connecting my bathroom fan, and straightening out the insulation around my skylight. Wojtek included these items in the very reasonable price.
The crew of 3 men and a large truck, showed up exactly as scheduled, to the minute, on the day of the appointment. They quickly completed the work, within about two hours, on my small home. They provided photos as well. The job was completed to well above my expectations.
The insulation gets blown in through a long hose, directly from the truck, to the attic. The crew took off their shoes inside the house, and even vacuumed up after they were finished. The job was done very cleanly, and this was much appreciated. They also took the time to explain what they were doing, and provided photos along the way.
The night after the insulation upgrades, the upstairs bedrooms were much hotter than usual. Instead of setting the thermostat to 24 degrees, as we had been used to, we were able to set it down lower, on the next night.
The temperature in the house is much more balanced now, and all the rooms feel more even. There is noticeable less temperature difference between the floors, and between the rooms.
I'm very happy with the results, and as far as heating/cooling upgrades, this is the best possible value for the money spent. I would recommend this for anyone who is noticing a temperature difference between various rooms in the house, either too cold in the winter, or too hot in the summer.
