If you are looking for a 100% honest service, look no further! I had a heater problem that was intermittent, a tough situation for technicians, Goettl was initially out and said they could repair it for $1800, their goal was aimed at selling me a new system, their technician was clueless.
Bulldog (Alan) properly diagnosed my system and my heater is working fine, the repair was $200.
I highly recommend Bulldog, no double talk, just great service.
Thank you Bulldog, when it's time to replace my old air conditioner, I'll be calling you.
