Amazing service from North Valley Mechanical! We needed to have our a/c and heating inspected each year and for the summer, with 19 year old a/c units we were concerned that they operate properly. We phoned North Valley Mechanical, a week later two technicians arrived on time (I actually received a text telling me they were on their way) They arrived about 8:15 and didn't leave til noon. We've had our units inspected in past years but never this thorough. They took apart both a/c units--cleaned every part. One problem in the unit located in the attic--one of the plugs was missing and there had been a slow leak in the pan. Chris replaced the plug and assured us that the pan was fine and they would make note and keep track of it for future visits. Another unit needed a pound of coolant. Simple fix. These two guys kept us up to date on what they were doing (even replacing batteries in the thermostats!); told us what they recommended we do; they were amazingly knowledgeable, professional, prompt, polite--we haven't had service people in our home this great in a very long time. We are thrilled with North Valley Mechanical and have a year contract with them for both systems. Thank you Kendra! Your family business is incredible.
