    We were very impressed by their responsiveness when our heating system failed. They had a technician to our home within two hours who evaluated the old system and indicated that it needed to be replaced. By the next day we had estimates … More for replacement and signed the contract. The quality of installation was very professional.

    Called JHC to install a mini split in my garage so I can "play" winter or summer . JHC said the installers will be at my home 11-24 8-830 am . They called to verify the install and time on Wednesday , The day of installation they … More showed up at 820am , and finished at 1230pm . All trash and installation materials were placed into trash boxes/bags and they hauled all their trash off . The guys were clean , neat , very professional . They tested the unit for proper operation before they left . Overall I was 100% pleased with the service , I would use John H Coleman .
