    We want to give a Shout Out to Heinanen Engineering! They replaced our Church's Sanctuary A/C Unit. Donations were made for which we can't thank them enough. The work was done efficiently and professionally. The crew was great; they educated us on all things A/C. The office staff has been and continues to be very polite, understanding and very helpful. We highly recommend Heinanen Engineering for your HVAC needs.

    I called for air-conditioning service on a Sunday night and they were out before noon on Monday on a hot day in May. Very very appreciative of their quick response. The technician had it resolved within an hour. I recommend them to anybody that needs quality A/C or heating service. I’ve been a loyal customer of theirs for 20 years.

    Steve was very knowledgable and had a lot of good insight on our furnace. Answered all my questions about keeping our system in check, they care about keeping their clients educated!
