I've relied on Hamilton Heating & Air for multiple service calls over the years and Mike has always been able to identify and fix the issues quickly. When it came time to replace our entire HVAC system, the experience was smooth. The lead time was faster than expected, installation was quick, and he even went out of his way to lend a portable AC unit while we waited for the new system. Mike is responsive, dependable, and has a level of customer care that's harder to find. I'd highly recommend Hamilton Heating & Air, LLC for any HVAC needs.

One Floor Comfortable, Another Too Warm
If rooms in your Queenstown home feel different, note which floor is affected and when it happens. A thermostat upgrade may help with control, but it cannot fix every airflow problem. A repair assessment should come before choosing more equipment.
