TESTIMONIALS

Excellent work and workers! My restaurant had our water heater break down right before the weekend and these guys found a replacement and had it installed the same morning! Fast, friendly and knowledgeable, we couldn’t ask for better. Thank you!

Used this company to finish up my AC unit. GREAT PEOPLE! Made the appointment and THE NEXT DAY they were there! AC unit took a little longer to install than we anticipated however the technician (Steve, possibly?) was great! Thank you for your hard work!

I received excellent service from Sentinel Maintenance, honest and good response for heating repairs. I did research so I knew ahead of time what basic repairs were needed. On short notice staff and service were great! I’d recommend this company!!!!
