"Greenwood did a fantastic job of installing a new furnace and thermostat in my home. The technicians showed my spouse and I how to use the thermostat in an easy-to-understand manner, and before they left they even vacuumed the floor of the area in the house where they worked! This wasn't the first time I've used their services, and it won't be the last. I highly recommend Greenwood Heating & A/C."

"Greenwood installed a new furnace at our house. The installers (Tony and Francisco) were great. We ran into an unforeseen design change (which we disagreed on price), but resolved those issues amicably."

"Kalen was a real professional and took the time to let me know the install process and gave me some options and advise on the location of the equipment. He was prompt, did quality work and showed respect for my property and how well the system would integrate with it. It was a pleasant two days with him."
