The whole-house air conditioning unit in our 85-year-old bungalow was approximately 30 years old, and despite regular maintenance had failed; it had been too small for the house from the start, and poorly installed. Corrosion and general compressor failure, coupled with its being undersized, led to the decision to replace the entire system.
We solicited quotes from several vendors, including Sutor on recommendation from our sister- and brother-in-laws, who were highly complementary. They were not wrong.
Greg came out to survey our home. He clearly enjoyed his work, was quite knowledgeable, thorough in his inspection and once he found that I was interested in discussing technical details, quite willing to discuss options, issues, and costs. Particularly as the previous owner hadn't allowed much room for the in-house coil/exchanger, it was a challenge to both boost the unit capacity and to fit in the limited space, but Greg not only found a unit but was able to shoehorn it in with a maintainable and professional installation.
His field technicians were prompt, friendly, and clearly knowledgeable in their fields. The work was carried out quickly with a minimum of disruption and mess, and they cleaned up neatly afterward.
Finally, he's available not only for any followup questions and problems, but just to discuss HVAC-related questions and ideas. And when my BiL's furnace failed to start during the frigid weather in Chicago in January, 2013, while he was out of town--and I was watching his house for him--Greg himself answered the 800 emergency call on Sunday night. (Incidentally, it wasn't a problem with the furnace he'd installed--the gas company had somehow let air get into the lines. We were able to walk through a purge and restart over the phone.)
Greg's price wasn't the cheapest offered, but frankly, the others were unreasonably--unbelievably--low, while his corresponded with what I could find about the costs of the unit and materiel. His company will most assuredly be the one I turn to when it's time to replace our 30+ year-old furnace. It's a true pleasure to encounter someone who's enthusiastic, intelligent, knowledgeable, and committed to their work, and has employees who embody the same attributes.
