Bought a HVAC unit from Allgeier Air on Jan, 2013 costing $8, 057.00. Not even 5 years later and I'm still financing this unit we start having problems with it. Called your company on 9/22/2017 because the unit wasn't cooling properly. Tech came out said there was a leak but couldn't find it. Added coolant for $239.00. On 11/17/2017 called another company as unit wasn't heating properly. They found leak and on Dec. 1, 2017 and replaced evaporation coil system. Unit started working properly. On 12/30/2017 unit not heating again and we placed call to the company that replaced coil system. Have to wait now till Jan2, 2018. I just don't understand when you pay this kind of money for a HVAC unit that's almost 5 years old why there are problems already with it. Your company should have looked into this more when tech came out and couldn't find leak but added coolant. A temporary solution knowing we would have to call someone out again soon. What kind of $@!#% units do you install anyway and what kind of techs do you hire? No calls to check on how system is running? Guess you got your money and ran. :( Upset and cold in Kentucky :( Another dissatisfied customer
