“Have had service contract with A-Advantage for over 20 yrs. Great service at all times. They installed our     heater, AC, attic fan, perform seasonal preventive maintenance and on the few times we needed some type of   service, they’ve come quickly & completed work professionally.  Wonderful customer service!”

“We had a problem with our heat not working a little over a year ago and had a couple of other companies out to take a look.  One said we needed a new circuit board and wanted to charge us over $1000.  Since my husband is a techie, we bought one online ourselves and installed it for around $180, but that didn’t fix the problem.  So we brought out another company and they said we needed a whole new system and wanted to charge us over $10,000.  We finally called in A Advantage for another opinion.  They took great care to look at our system thoroughly.  Come to find out, there was an old wasp nest that was blocking something in the system.  He removed that and it was working fine afterward.  He even showed us the pipe on the roof that we needed to cover to keep wasps from getting in there again.  We only had to pay like $150 for his time.  We appreciated that they weren’t out to sell us expensive parts we didn’t need, they were just there to do a good job.”

“Your service mgr John who visited today was exactly on my wavelength, spoke and explained in layman’s terms so I understood why he recommended what he did. I was impressed with his 20+ years of experience there, his respect for your company specifically, the lack of sales pressure, his looking out for my efforts to minimize upfront costs, and clarifying how your ten year warranty beats rivals because it covers not just parts but labor for all ten years plus unique in that it’s transferable for a fee ($150 I believe was the figure). I will pass the word around elsewhere to neighbors, friends, family, Washington Consumer Checkbook, and other websites about your company and my experience with Job. Great job!”

“I have used A Advantage for several years to service my heating and AC system and have been very satisfied with them. I know just about every one of their technicians in my area and am impressed with their knowledge and professionalism. Earlier this month, my 25+ year old system incurred a casualty that was not cost effective to repair. John was out promptly to inspect and advised me of the system status and prepared some options for me to consider. Repair was possible but not cost effective and after over 25 years, the old system was not efficient. The very next day at 8 a.m. the installer arrived and began the removal of the old system and installation of the new system. After installation and clean up, he showed me how to operate the new system and answered any questions that I had.”

“Was impressed by your quick response when out carbon monoxide sensor was going off.”

“The tech was very capable. When he came in he checked the panel on the wall and showed me that the issue was a need for new batteries…and didn’t make me feel stupid for assuming that it was hardwired. I now know how to change the batteries once a year. Thanks for the great customer service!”
