I first worked with Astello on an emergency project at my workplace and was so impressed with their responsiveness, professionalism, and quality of work that I decided to use them again for a heat pump installation at my own home. Once again, they exceeded my expectations. The entire team was easy to work with, communicated clearly, showed up when promised, and kept everything immaculately clean and organized throughout the 2 days they spent in my house. I really liked how they handled an unexpected issue: one of the planned units didn't fit the space as originally anticipated. Instead of causing delays, they quickly came up with alternative solutions, explained the options, went out to get the replacement unit and kept the project moving without skipping a beat. Even with that obstacle, everything was completed the very same day as promised. Another advantage was that Astello took care of all the paperwork, permits and rebates, making the process completely stress-free for me. It's refreshing to work with a company that does what it says it's going to do, communicates well, solves problems quickly, and genuinely cares about my satisfaction. Based on my experience with them, both professionally and personally, I have no hesitation to highly recommend Astello to anyone looking for a reliable, responsive, and customer-focused Ductless contractor.

Vadim and Roman are GREAT to work with. They are respectful, neat, efficient, and willing to work with you. I highly recommend them if you are installing heat pumps in your home. They gave great advice, and I love the way the entire system looks in my home. I couldn't be happier with the results!
Vadim And colleagues were great to work with. The great communicators do excellent work, highly responsive, and move quickly. I will certainly use them again and recommend them to anyone.
Very reasonably priced, knowledgeable, fast and clean work, I’m very happy with the whole home heat pump mini split system that was installed and would recommend Astello for anybody looking for the same!
Very knowledgeable and up front during the estimate. Professional and experienced crew that finished install in one day but still got all the details right.
Astello was fantastic to work with. I had zero experience with HVAC and no idea what to expect going in, but they made the whole process easy. They came out for a walkthrough, asked what I was looking to accomplish, laid out my options clearly, and gave me a solid timeline. They showed up on time every day and were professional, courteous, and easy to deal with throughout — They even finished 3 days ahead of schedule. The result has been great: my house stays comfortably cool, and it's a huge upgrade from noisy window AC units. They also handled the paperwork for a NYS clean energy rebate on my behalf, which was a nice bonus I wasn't expecting. Highly recommend Astello to anyone looking to get HVAC work done right.

Ductless Mini-Split & Heat Pump FAQs
Do heat pumps and mini-splits work in Capital Region winters?
Yes, when the system is selected and sized for the home. We compare your home's heating needs with the cold-climate heat pump's output at the winter temperature used for sizing in your area. We also discuss whether backup heat is needed.
How much does ductless mini-split installation cost?
The price depends on the equipment, how many indoor units your home needs, where they go, access, electrical work and permits. We check these details during the home visit and prepare a written estimate.
Can my project qualify for NYS Clean Heat rebates?
It may qualify. Eligibility depends on your electric utility, property, equipment and heating design. A rebate is not automatic for a room or cooling project. We check the program requirements for your project. The utility program determines eligibility and the final rebate. See our rebate information.
Do mini-splits heat and cool without ductwork?
Yes. Ductless mini-split heat pumps provide heating and cooling without air ducts. Indoor units connect to an outdoor unit through refrigerant lines. They can serve a whole home or individual spaces, such as a room, garage or addition.
What size mini-split do I need?
The size depends on how much heating and cooling your home needs, not floor area alone. We use a Manual J load calculation that accounts for insulation, windows and other building conditions, then plan the indoor units around the spaces you want to heat and cool.
What areas does Astello serve?
