Convenient maintenance

I scheduled an appointment for an AC maintenance which was carried out in a timely way with no difficulty. I appreciate having a detailed report and a sense of my older system's condition.

Excellent service

Andrew was responsive, knowledgeable and respectful. He got the job done and his repairs look great. I give him 5 stars. My issue is that the cost seemed out of line with the work performed. With only minimal parts replaced, the job took just under 3.5 hrs. The price of $800 seems to indicate a labor rate of around $200/hr. I have not had much plumbing done over the past several yrs but that seems high. I will continue to use Xtreme but would like to see your invoicing break out parts and labor. Again the service was outstanding and the leaks have been repaired. Thank you

Upon arrival unit was off. Had customer turn the unit on and checked the pressures. Pressures were 9/93 which is very low for a R22 system. Advised against adding any refrigerant to the system due to how low the pressure is and the age of the system. Took pictures for a replacement quote.

Checked systems. The water heater was not off on reset and it was up to temperature. Started and tested. The furnace was off on reset. Reset the control and it started. When the burner was running, the flame was rumbling. Checked the oil flow and found the nozzle partially plugged causing the oil to spray everywhere inside the chamber. Replaced the nozzle and burned off the excess oil in the chamber. Started several times. System is operating properly. The nozzle may have became partially plugged after running out of oil.
