I hired BE in 2022 to install a two ton heat pump system to replace an old Bryant furnace. David, Beto and Homero worked with me to also install some new duct work to make my living room more comfortable–as like many homes built mid century, my living room was originally more reliant on supplemental heating from the fireplace and that didn't really work well. The work took two days and I was walked through the steps beforehand. It's been working well and my home is more comfortable. (I have enj

I worked with Building Efficiency and the owner David last year to bring my (new to me), 85 year old home up to today's efficiency standards. I had done a lot of research beforehand and had lots of questions/ideas/opinions on what I wanted to do. This included going fully electric for heating/cooling with a heat pump, new central air ducting, replacing gas hot water heaters with heat pump water heaters and fully insulating the walls and attic. David spent the time with me to go through all my

Amazing local business! I had the team at Building Efficiency replace our gas furnace with a new, central heat pump. At the same time, they added blown-in insulation. The entire process was smooth and was handled very professionally. Our home is much more comfortable than before - and greener as well. We had such at great experience with Building Efficiency that we also had them replace our gas furnace with a SanCO2 heat pump water heater. That job was also handled extremely well. We are

I got solar panels installed in 2023, so I wanted to eliminate gas and go totally electric. I chose Building Efficiency after getting four different estimates. The whole process from start to finish, working with their crew was great.

David and his team installed a heat pump and heat pump water heater in my home several years ago, and I have been very pleased with them and Building Efficiency's ongoing support. When my garage was flooded in late 2022, David and his team helped troubleshoot the heat pump and made sure everything was running smoothly. More recently, I had plumbing issues that required another service visit, and the team was just as responsive and efficient as before. I highly recommend you go with Building Effi

The Building Efficiency team installed 2 heat pumps (1 of them shown in the photos, the other is in a crawlspace that's a little hard to get to), heat pump water heater (shown), new ducts, and attic + kids' room insulation in my 75+ year old home. They did this quickly and efficiently (in under 1 week despite needing to re-duct our home and the random space constraints you'd expect with a 75+ year old home), helping us get the rebates we qualified for and making sure what they put in fit our hom

Dave and building efficiency were the most knowledgeable contractor which I interviewed for our project to install a Heat Pump system in our house. Unlike, several others, Dave sized the system accurately and had clear expertise in the technology. He included improvements to our ducting system which others did not. The pricing was very competitive. Although we had a long wait for our installation, when it occurred, it went smoothly and efficiently. The crew clearly was well experienced and exper

We did insulation on our 100 year old plaster and lath house and the results have been excellent. Quieter and the temperature inside is now very stable. Even with a few windows open a little the inside temperature hasn’t gone below 63 or over 70 for weeks now which is perfect for us. We live in the City College area so it’s been fog and wind since we had it done. We also had a heat pump installed but other than running it to test for a day neither heating or cooling hasn’t really been needed y
