Services
Geothermal Heating Systems
Geothermal systems utilize renewable underground energy for efficient heating and cooling. Our closed-loop and open-loop designs reduce operating costs by 60% compared to traditional systems while qualifying for 30% federal tax credits. These environmentally friendly solutions provide consistent comfort with zero on-site carbon emissions.
Ductless Split Systems
Ductless systems offer zoned temperature control for homes without existing ductwork. With SEER ratings from 15-33, these quiet, energy-efficient units eliminate window unit drawbacks while adding home value through permanent installation and enhanced security.
Hybrid Heat Pumps
Hybrid systems combine heat pumps with fossil fuel furnaces for optimal efficiency. By using the most cost-effective fuel source seasonally, these systems can reduce annual heating costs by $1,400 or more while maintaining comfort in extreme temperatures.
Planned Maintenance Agreements
Our Bronze, Silver, and Gold maintenance plans extend equipment lifespan through regular professional servicing. These agreements include priority scheduling, discounted repairs, and system performance optimization to maintain efficiency and prevent unexpected breakdowns.
Commercial HVAC Solutions
Custom commercial HVAC design includes computerized heat gain/loss calculations and custom ductwork fabrication. Our sheet metal shop supports tailored solutions for new construction and retrofits, ensuring optimal climate control for business environments.

Person was very professional. Explained to each steps. He performed every task in a timely manner and actually the cost was less than I had paid few years ago to another company.

Evan was thorough and efficient. He explained details about the condition of our HVAC system and made recommendations. We appreciate that he wore a mask and booties, and cleaned up after he was finished. Service: HVAC system repair

J.A. Smith installed a Daikin heat pump for me. They are professional and responsive. I never had to rush them to do anything. Also, they allow me to choose any electrician to wire the power they need. Very happy with the heat pump now. Will hire them next time I need something they can help.

Brandon identified the root cause of the problem in moments (improper installation by another contractor.) He showed me the damaged copper fittings after removal and replacement. He required less time than the estimate (trouble free repair) so, the cost to us was less than the original estimate. Service: HVAC system repair

Hired this company for a water heater install. The guys were punctual, professional, and friendly. They ran into a bit of a snag but got what they needed to complete the install and everything seems to be working fine. I have no problem recommending them.

We actually did this remotely. Bob serviced our apartment water-source heat pump. It's hard to find people who can do this. He showed on time, got the key from the lock box, did the work quickly and efficiently, and called promptly. I will use his services again given the opportunity.
