Recently, my AC unit was causing condensation to leak into an area that it shouldn't be. This was caught early because of our scheduled inspection. The leak was fixed within the same day! The professionals helping me were incredibly respectful, patient, and kind. The technician worked with me to ensure that the fix would be within my budget and still resolve the problem. I especially want to thank Christian Ruiz! He has always ensured that my heating and AC are safe. He has even gone above and beyond by showing me where the gas lines were, checking to make sure the ones not being used are off, and teaching me about potential fire hazards with my washer and dryer and how to avoid potential issues. He also taught me how to maintain my water heater so I can help it last longer. I sleep better knowing that I can always call Cencal with any issue regarding my heating and air. They have always provided safe and swift care every time. Signed, a customer of 8+ years.

I often leave very positive reviews about Cencal as a company. I want to also mention their employees. The technicians, service people and office staff are delightful to work with. I have gotten to know quite a few over the years of doing business with Cencal. They have all been very kind, understanding, professional, and knowledgeable. The one I have had most recently is Christian. I want to thank him personally for his excellent service and his pleasant demeanor. It’s always a joy to see him come to the house.

Update 2026- HVAC routine check up before Winter. Very good Service. Polite efficient employees. Sorry I just remember a name Christian like my grandsons. Very nice people work for Cencal. I find them very honest. Update It’s been two years and very happy with the choice to have Cencal install our HVAC system. Works great. Seasonal check by a Cencal employee is a great service.-2026 2024-After meeting with Brandon, the sales representative for Cencal, we decided to install a new HVAC system as ours was over 30 years old. We decided to install all electric and so far it’s been running just fine with no problems. They will come out twice this year for routine maintenance check at no charge. The installers Zach and Sean were very efficient. You couldn’t tell they had been here with no mess to clean up. Brandon, Zack and Sean were all very courteous. It was a full day of work for them. I will update later if there’s any problems with the unit it is a Bosch Seer 18, so far our home is keeping cool and the Ecobee thermostat works just fine especially with the app on my phone.
