Matt McNeil is a great guy, very knowledgeable about equipment (heater, in this case), was prompt and available same-day/next-day as we prep for spring break in our pool/spa, and dedicated to my happiness. I have lots of price questions and he helped me understand on every topic about which I enquired while having rational boundaries. Good degree of transparency, which I require. Many contractors are threatened by that but I maintain that there is no issue with somebody making a fair amount of coin...but transparency is important to avoid being fleeced and, for those that won't provide it, I have to assume I'm getting gouged. My prior guy did not have this transparency and, sure enough, things didn't add up. As with most professionals, I have little means to validate Matt's diagnosis but saying an 18 year old heater is best replaced with a more efficient brand new heater, not bandaided for hundreds at a time, is pretty straightforward. Owning a pool is like owning a luxury car...a big check could be around the corner at any time. I don't fault Matt for that, and I am very pleased with Matt, giving him 5 stars for the many reasons noted. As with all things, I choose to work with expert (realtor, car sales, pool...whatever...I need an expert). Matt McNeil is clearly an expert.
