What Our Clients Say About Us

  • "Everything went great. Two installers arrived at the time agreed upon, were polite, professional and efficient. Kept everything clean while working and afterward. Finished job sooner than expected. Made sure the equipment was working properly. I would recommend Bolls to anyone."

    Service: Deliver and install new Lennox furnace and air conditioner, new Honeywell thermostat. August 25, 2014

    Leonard – Greenwood, Indiana

  • "Sergei and his team are fantastic. Sergei used a copy of our home's blueprints to outline our system and did an extensive walk-through with one of his most experienced technicians to make sure our system could be installed flawlessly and work perfectly. I was expecting some snags here and there, working in a home built in 1972 with some very unusual features. The team didn't encounter a single problem, more than likely due to the amount of thought and attention that went into the planning process. Also, with such meticulous planning, there were no surprises with cost. We paid exactly what was written in the proposal. It was a very extensive installation, but the technicians and company were extremely courteous and professional. I am a stay-at-home mother of a small baby and their work hardly disrupted our routine at all. The technicians sought my opinion before any aesthetic steps to ensure I'd be happy with the final product. They even put custom mesh grates in the floor diffusers at my request (so our little girl won't be dropping things into them!). The system works beautifully and was well worth the money we spent. I would hire them again in a heartbeat!"

    Service: Customized installation of a high-velocity, variable-speed air conditioning and heat pump system in our post-modern home. August 05, 2014

    Leslie – Anderson, Indiana

  • "Technician came out, tried to fix the problem in a less-expensive way but that didn't work so I needed a new AC. Sergei came out, assessed my needs and answered my questions. He was clearly knowledgeable about this area and he provided an estimate. The installer, Mark, was also knowledgeable and confident, so I felt that I had been taken care of very well from the beginning of my contact with Bolls to the end. It took a lot less time than I expected from my first call to when Mark walked out the door. Communication between Bolls and myself was excellent. I got a total of 3 estimates so I know Bolls price was reasonable. All 3 men were clean-cut which presented a good image for the company. I felt completely at ease with having them in my home. Mark needed to come in and out and I had to leave and I was perfectly comfortable with that. In fact, I didn't think about it at all. I've used another HVAC and Plumbing company since 2000. I'll be calling Bolls from now on."

    Service: Central air not cooling.  Bolls installed a new AC. August 01, 2014

    Debra – Indianapolis, Indiana

  • "It went very well. I was very impressed with the professionalism of the Bolls tech, who was diligent in diagnosing and fixing our specific problem – without trying to "up-sell" me into paying to replace much more than was really necessary. Bolls found the specific replacement part within a few days and the tech quickly returned and fixed our system for a total cost (both visits, including the new part) of $305. This has corrected our problem!"

    Service: I initially had another company evaluate the two-level electronic zoned damper system for our air conditioner because our lower level was always too cold – substantially cooler than the thermostat setting. This first technician did a cursory evaluation and stated that, at a minimum, the lower level zone damper needed ...

    Michael – Fishers, Indiana

  • "The installation crew was as good as the service folks. They were professional, punctual, and friendly. When the new compressor failed (likely damaged during shipment) they got a replacement unit quickly and had it replaced within 2 days. I have used several HVAC companies over the years and I have found none better." Service: Removed old A/C & Furnace, installed new unit.
