Christian was great! It's almost impossible to get someone to come out same day, especially when that day is the last of the year (12/31). I must have called 8 places, and scheduled an appt. online for Triton to come out 1/2. But, within 15 minutes of my having scheduled the online appt., Christian called me and said he could come right out. Plus, the charge for the visit, new thermostat, and labor was really affordable! Really nice guy, too. Yay! I will definitely be considering Triton to put in my new central heating so we're not as freezing next year!
