"My mother paid almost $6000 for a comprehensive energy review from Home Comfort about 4 years ago. This winter, she had a huge ice dam that caused damage inside. I called Home Comfort to investigate and they initially responded immediately, made an appt to come and then never showed, never returned my calls."

"I rented for seven years. It was a constant nightmare. No pest control, maintenance requests are just ignored or months late, rent hikes are constant. Total scum lords. Rent hikes costed me $700 monthly ($100 more each year) Told me to pay for my own pest control for the rodents and roaches at this property and won’t pay me back (totally breaks the law and doesn’t care) Using rent fixing as well. Run for the hills, hopefully these terrible deplorable peoples will shut their doors soon."

"Initially, we thought that all went well. Then when we needed to contact the company for the second phase of the work, it took multiple calls to reach them and get an appointment set up. Then multiple calls were required to get an appointment set up for an annual inspection of the furnaces in our home. By the time the third phase of the work was to be done, installation of a whole house AC unit, our frustration level was high with the previous lack of response, so we called in another contractor to get a new quote. At that time, we were told that the evaporator coil was not installed correctly and to fix the issue there would be an additional $1,500 in labor costs. I then spoke to another HVAC engineer and after talking he agreed the coil would not work as installed. To follow up with that, the local representative of the furnace manufacturer and AC unit came and looked at the installation, and agreed that the system would not work as initially installed, and if it did work at the start there could be problems down the road because the condensation from the coil would not be able to drain as required. When I was finally able to contact Eco and communicate with the owner, which he would only do via email, he stated that he disagreed with the information provided by the other people I spoke with, and he felt he had solution to the problem (but that wasn't part of the original quote for the overall project.) In the end, his final words were "If your other contractor can't figure that out, I suggest you keep shopping. We thank you for your patronage, and wish you the best of luck." Not much help, in our opinion. When all was said and done, we had to have most of the work that Eco did redone. Although the previous reviews on this company were good, that was not our experience."

Energy Efficiency Auditing questions, answered by experts

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.
