HVAC Technician Recommendations

[Kobi Mashnouk]

Does anyone have or know of a solid HVAC Technician in the Tulsa area who is trustworthy and does a good job? We are out of state investors and own a strip mall in the Tulsa area. We have constant issues with our units and have paid too much money to a few contractors in the area who conveniently have averaged $1,640/month of work the past 3 years with redundant issues. Would greatly appreciate any referrals. Looking for someone who is reliable and trustworthy with fair pricing. We have a property manager, but this situation has gotten out of hand and we need to find a go to HVAC tech to use moving forward. 

Any help/input is greatly appreciated!

Thank you all in advance.
