On January 16, 2024, during one of the coldest days of the year, my heating system malfunctioned, leaving me in a freezing home. In my distress, I reached out to Vanguard Heating and Air Conditioning Inc., where I spoke with Dawn, their representative. She was initially quite helpful and promptly scheduled a technician to come to my house at around 2:00 pm. The technician, Al, arrived on time but appeared to be experiencing some physical discomfort, possibly due to back issues. He moved slowly and even brought his own step stool to sit on during the service call. I had specifically mentioned to Dawn that my heating unit was a unique one, utilizing a reverse electrical heater pump. This type of system is different from a conventional heating system, as it also functions as an air conditioner when needed. However, it became evident that Al might not have been well-versed in this specialized system. He asked for the location of the unit's off switch and the position of the boards inside the unit, which raised concerns about his familiarity with the equipment. To assist him, I explained what I knew about the unit and showed him a similar one we had in our home. During the service call, Al spent a considerable amount of time on the phone, discussing the issue with someone else. This, combined with his slow movements and questions about the unit's basics, led me to question the efficiency of the service. Furthermore, the charges amounted to $45 for every 15 minutes, which raised my concerns about the cost. I eventually expressed my apprehension to Al, explaining that I couldn't afford to pay for his time spent sitting idle. He continued to move slowly, going up and down the stairs multiple times and checking the outdoor unit. He determined that the "outdoor unit was running with a condenser fail" and turned off the breaker. He assured me that the heater would gradually start working, raising the temperature by about a degree per hour. However, the actual results were far from satisfactory. According to Al, his thermometer showed an increase from 60 to 61 degrees Fahrenheit, but the temperature in the house, according to the thermostat, actually dropped from 60 to 59 degrees Fahrenheit. Upon completing the service call, Al presented me with a bill totaling $379. This included a service call fee of $68, a diagnostic charge of $127, and a labor charge of $184. Unfortunately, he couldn't provide a clear diagnosis or solution to the problem. After receiving payment, he left promptly without discussing the issue further. Feeling unsatisfied with the service and results, I immediately contacted Dawn, who assured me that the owner, Gary, would call me. I received a call from Gary two hours later, during which time the thermostat showed a further drop to 57 degrees Fahrenheit instead of an increase. Frustrated and in dire need of warmth for my family, I resorted to purchasing additional heaters from Home Depot. However, I decided to seek a second opinion and called another heating and cooling company. Their technician discovered a burnt cable and identified several other compromised components within the system. He also pointed out that the screws to access the coil compartment had not been opened in years, making it impossible for Al to inspect the coil. While this was happening, Dawn informed me that Gary was on his way to my house, but I had lost trust in Vanguard Heating and Air Conditioning Inc. and declined Gary's visit. In hindsight, I wish Vanguard had been upfront about their expertise with this type of equipment. I would have preferred seeking assistance from a more knowledgeable professional rather than spending a significant amount of money without any improvement in the heating conditions. The contrast in findings between the two companies further highlights my dissatisfaction with Vanguard's service.
