Our outdoor heat pump unit was frozen a few weeks ago. Our neighbor referred us to Zone Control. We called them during after hours but since we were still getting heat inside the house it wasn’t considered an emergency. However, Sandra was very prompt in calling us back early the next morning to schedule a tech to come out. Since our unit was completely frozen both inside and out we had to take time to thaw the ice out. Ronan and Hector diagnosed a bad defrost board and capacitor. They gave us estimates and came promptly to do repairs once the parts were available. Overall we were very satisfied with the service and would recommend them to anyone needing HVAC care.

I had been dealing with an issue with my 4-year-old furnace for the past two years. Whenever the outside temperature dropped below 35°F, the system would shut down the thermostat and fail to restart. I had two different companies come to diagnose the problem, and while both suggested costly repairs, none of their fixes actually resolved the issue.
Finally, I reached out to Zone Control, and technician Ronan Queiroz arrived promptly. After explaining the issue to him, he immediately began diagnosing the root cause. Unlike the previous technicians who simply replaced parts without addressing the underlying problem, Ronan took the time to thoroughly analyze the situation. He determined that the system's intake was too small to properly cool it down, which was causing the shutdowns. His solution was to install an additional intake, and ever since, the furnace has been running smoothly for the past two weeks.
I’m incredibly relieved to have this issue finally resolved and highly recommend Zone Control—especially Ronan. His expertise and attention to detail truly set him apart; he’s the 'neurosurgeon of HVAC'!

Zone Control provided a friendly customer experience from beginning to end for our HVAC needs. Specifically Sandra was very helpful on the phone and our technician Ronan was very knowledgeable and efficient in-person. Pricing is also reasonable. Thank you Zone Control team.

Ronan was great!! Thank you so much - they came and immediately were able To troubleshoot and fix our heating unit, getting it back up and running within an hour! Very easy process and they weren’t trying to upsell us on anything. We had heard good work Ronan does and he certainly lives up to his good reputation! Thanks so much!

Our AC failed late one night on one of the hottest days of the summer and Zone Control was able come out that same evening. Their technician was a true gentleman who took care of the initial problem so we could have AC that same night, but had to come back the next day to complete the needed repairs. The cost was very reasonable and the service was exemplary. We will call them in the future for all our AC/Heating needs.

We have Zone Control out after we had another company out to say we need a new unit. Then some one recommended them
and they came out and repaired the unit at a lot less cost. Very
nice company to do work with .I would recommend them to anyone their people are very professional.
