I am so glad I found Halo HVAC through Yelp! My AC stopped cooling in a heat wave and I had many…read moreother companies quoting me $200++ for diagnostics or unable/unwilling to come out for weeks. I went to Yelp looking for a better option and definitely found one! Halo was able to come out within a couple days of contacting them and the diagnostic fee was $89, which was to be applied to any work performed if needed. it turned out it was a tripped breaker they were able to reset and my system is cooling perfectly again... for $89!! The most notable and appreciated factor for me is they didn't come in trying to sell me service plans, upgrades to my system or accessories, or otherwise upsell me on a well maintained and well functioning older HVAC system. Even when I asked for a quote on a heat pump to take advantage of the rebates while they last, Halo didn't push me to pick the most expensive option or upsell me on a pricier type of system. And icing on the cake - despite a lot of in and out while working on figuring things out, my technician was constantly putting on and taking off booties to keep my house clean. It's a small token of respect that goes a long way, and I very much appreciate it! I'll be using Halo and referring them to friends and family in the future!
