Great customer service. They were out in the afternoon servicing my account unit that wasn't…read moreworking. They diagnosed the problem and fixed what they thought was the problem. When I got home from work, the AC unit was still not working. I contacted them and the owner was at my house within 20 minutes. The problem was diagnosed and fixed. Upon packing up, he went and got the check my wife had written earlier in the day and told us because of the error, he was not charging us anything. We tried to argue that his time was valuable but he was hearing none of it and wouldn't accept anything for fixing our problem. I won't use anyone else from this point on. Honesty and integrity hard to find these days and when you run across them, you keep it close by.

This company is a joke! Our air conditioner stopped working so we called Valentine for an estimate…read morefor a full replacement.After spending a few minutes looking at the system, they proceeded to write a quote. For our relatively small, 3 bedroom house we were given a quote of $30,000!! After telling Valentine this is outrageous, they responded by saying the cost is so high because it includes their "premium service plan." On top of this outrageous quote, they tried to charge us $650 to come out for the estimate. We refused to pay. The technician then laughed and said "whoops, I think my math was wrong."We still ended up paying them $350 but it was worth it to get them out of our house. Had 2 other replacement estimates done by 2 other companies; both were less than $7,000. Not even sure if con artist is a strong enough term. This company is simply dishonest and will say anything to get as much money from you as they can. There are plenty of other HVAC services in the area. STAY AWAY FROM THIS ONE!

The annual service for my A/C was very thorough, and during the technician's visit, they checked…read morethe furnace and discovered a cracked heat exchanger that might have existed since the severe winter of 2025-26. I promptly arranged for repairs, as I occasionally use the furnace on cooler nights, even when daytime temperatures don't require it. Unfortunately, the first appointment was canceled at the last minute, and the second appointment couldn't be completed because the new heat exchanger arrived damaged, necessitating a reorder. Additionally, I was overcharged for cleaning the blower, which wasn't performed due to the heat exchanger issue. I'm still awaiting a refund and am uncertain about when the furnace repairs will be finished. This situation could have been managed more effectively, and I hope everything gets resolved soon. I will post an update when everything is completed as requested.
