I wasn't in a rush for central air and talked to 4-5 companies in the past year. Some were heavy on sales and magic payment plans, some were strong on brand but had high prices to match, the people who seemed the best to work with carried brands with terrible ratings. Cozy World was the first that met all my criteria: a well-rated brand (Goodman), quiet operation (several db lower than the competition, and Boris suggested both the vibration-absorbing base and base pad), all at a reasonable price.
So far so good, but as all A/C reviews show - long-term happiness varies directly with the quality of the installation (look for Goodman reviews, they tell this story real well). The Cozy World team met or exceeded my expectations in every way. It was a difficult route to run the line out. Boris planned for access panels where drywall would need to be opened up. Then the team came and figured out how to do it with fewer holes. They found and fixed a slow gas leak in two of the joints that were being moved. I suggested they remove the humidifier if they needed more room to run lines, as it came with the house and hadn't ever worked. Instead they saw it wasn't correctly wired and fixed it. These guys are exactly the people you want, they really do leave every situation better than they found it.
Cozy World was fantastic to work with. I'll recommend them every time and look forward to working with them on whatever heating, cooling or gas line need comes up next.
Cheers,
