If you're looking for great service and people you can trust to handle your HVAC needs, I'd look no further than Cardinal Heating & Air Conditioning. My wife and I purchased a 25 year old home and we called up Cardinal to come check out the furnace. The tech who showed up was awesome. He let us know that the furnace was the original furnace, which even he was a bit surprised about (since they typically only last about 15-20 yrs), but he said it was still functioning just fine despite its age and didn't try to sell us on anything at all. We ended up liking our tech so much that we signed up for Cardinal's annual preventative maintenance plan for heating & cooling; which I'd highly recommend. Anyway, over several years our furnace kept passing inspections (in which at no time did anyone at Cardinal pressure us to upgrade), and the service maintenance checks we had with them were all great experiences.
Finally this past spring we had a tech out to check the A/C unit as part of our annual maintenance plan, and while he was running a diagnostic on the A/C he went the extra mile and used his down time to check our furnace; which thankfully he did, because he spotted a crack in the heat exchange (which I also verified was there). Now if you're unfamiliar with furnaces, a crack in the heat exchange is a serious issue; the type of one where you run the risk of carbon monoxide leaking into your house. The tech was very apologetic for having to inform us of the bad news that by law he had to flag our furnace as unsafe to operate. However, I just profusely thanked him and said we knew the furnace was well beyond it's expected life, and that this was precisely why we had the maintenance plan in the first place. Anyway he went on to finish the air conditioning check that morning, but before doing so he called the office to have someone reach out to us about our options for a new furnace. As expected they got back to us pretty quickly (within a half hour).
Now I should also mention that our A/C unit was pretty old (13 yrs), and they typically only last 12-15 yrs. So it wasn't too surprising when he said it would be an extra $200 to top off the coolant and replace a part. He also estimated that even still, the unit would only have a year or two left before ultimately needing replacement. However instead of pushing the repairs through or trying to sell us a new A/C unit, he told us to hold on for a minute, and he called up the office to see if they were still running a promotion that was ending soon where if you buy a furnace (which we were already going to do through them) that you get an A/C unit free. It turns out that they still were (and had it been a few days later we would have been totally SOL), but in doing so he got them to revise our quote on the new furnace to include the new A/C unit. As a result we ended up saving thousands through this deal. And for those of you skeptics out there, no this wasn't some manufactured promotion that was put together to make the sale happen. We were already going to get the furnace from them, our tech simply was looking out for us and in doing so he saved us a lot of money.
Lastly I also want to mention that at the tail end of the A/C check-up I had to head to work, but my wife was home, and so we talked on phone the remainder of the morning sorting out all of the above. Now where things went from great to outstanding is when she called to inform me that Cardinal called to schedule the installation and the scheduler was like: are you available this afternoon? My wife was shocked, and confirmed that she was in fact implying that the furnace would be installed that day. She said: yeah, it looks like it might get a little chilly tonight, so I thought if it worked out we'd try to get that installed today for you. So low and behold when I came home from work, they had removed the old furnace and A/C, installed the new units, and to top it off hooked us up with a new smart thermostat that worked with our 4 wire system (unlike our Nest) and had taken the time to walk my wife through all the features on how to use it.
So there you have it. If you've braved through my very lengthy positive customer experience story, you'll see why I'll be a Cardinal Heating & Air Conditioning customer for life. And for those of you who prefer the cliff notes... let me just say that Cardinal does excellent work, has excellent people, their work is timely, they are not pushy about trying to sell you anything, and that ultimately the cost of the new furnace and A/C was far less than the money we had budgeted for it. Thanks to them I sleep better knowing that my wife and kids are safe because the crack in my heat exchange was caught when it was. With the Cardinal, I feel like they truly have your best interest in mind, and I honestly can't say enough good things about our past several years of being customers of theirs . Thanks Cardinal!
