Recent Reviews

We highly recommend Stewart Heating! Why? The excellent service from technicians like Jamie who go above and beyond! Let’s just say he was sent away by my aging parent who got mixed up about what he needed serviced on his heater. Jamie respectfully left after making an assessment. I called Jamie back to clear things up and explain what we needed and he was able to come back the same day and have that heater repaired. In addition, he completed some standard maintenance while he was there. In a world where caregiving from a distance makes getting belp tricky, this was a moment that mattered for our family. Trust and excellence across the board! We would absolutely work Stewart Heating again! Even Victor who helped me set up the appointment was timely and supportive. We will be back!

Diligent and efficient in diagnosing and completing the repair. Professional service and timely communication. Such a welcome change from home warranty vendor nightmares.

Thermostat panel went blank the night before. I replaced batteries and it came back on only to have it go blank again on me later on. Stewart heating and air was called the next day, and they showed up same day in the morning. Determined it was a faulty thermostat. Replaced it quickly and got my heater back and running.

Carlos our technician was very professional. He called ahead as requested and on time. He was respectful of our home and communicated well his findings. We would love to have him back.

We had our water heater service (cleaned and flushed) by Walter from Stewart plumbing and right from the appointment time to the job completion time - everything was perfect - Walter showed up on time and did the job on time. He was patient enough to answer my questions. Fully satisfied with the job outcome and I Totally recommend this company.
