$500 Off New AC Installation
Summer has a way of showing up all at once — and when the first heat wave hits, AC installation schedules fill up fast.

Beat the rush, avoid emergency breakdown stress, and lock in $500 off a new AC installation before peak demand begins.*

The new furnace was installed on January 26, and a few days later the heat pump.
Because we are not very tech-savvy, it seemed as if the furnace was running too often – it was the coldest time of the winter! We contacted Comfort Zone again.
A.J. has just left and he explained – very patiently – exactly how the thermostat works; he programmed it to our specifications.
And he ensured that we are now comfortable with our new system.
We certainly appreciate how A.J. took the time to ease our minds. It is more difficult for our “older” minds to grasp newer concepts. But A.J. did a great job, and we thank him very much!!!
A. J. got my furnace up and running again in a very timely manner and was very helpful explaining the furnace issue.
He was very efficient and knowledgeable about the problem we had. A very nice young man. One week later we had Hakim come. A very lovely young man to replace the temporary one put in by Paras.
He too was efficient and knowledgeable. We are happy with the service by both Hakim and Paras.
Service came out -ventor motor-ordered and installed 12:00 pm Wednesday. Hakim was our service tech who installed the motor – knowledgeable, efficient and polite. He also talked to us about next steps down the road – (pressure free) as we will be looking at a heat pump next year. Awesome job! From start to finish Comfort Zone responded quickly and communicated well.

[UPDATE] Bosch eventually supplied the replacement unit and Comfort Zone scheduled the install for Friday morning. In fact Jeremy and Joe were able to come early and made extremely quick work of the removal and replacement. All settings were configured as per the original unit and prolonged tests proved that the new unit (unlike the old) could supply hot water continuously. Many thanks to Jeremy and Joe and the whole Comfort Zone team.
Josh came by the next day to discuss replacement. Provided good info and resonablybpriced options.
On Monday Courtney and Joe installed a new furnace. They were efficient, took care to not bump walls and doors; answered my numerous question. They kept the work area tidy. The completed the work in a timely manner.
Comfort Zone staff and techs have provided a good experience.
Your comfort and confidence come first. Every Comfort Zone service is backed by clear promises you can rely on.
