Best Gas Furnace Repair in Tampa FL

I'm military retiree who has travel around the world and this person is one of the most honest contractors I hired. Thank you!

Marcos came out to us and diagnosed our plumbing issues quickly! I had numerous estimates prior to this and was quoted the best pricing from Lakeside. Excellent customer service and highly skilled plumbers found here!

Northside air conditioning has just put a new unit in our home. From the very beginning when Mike came out to check our old unit he couldn't have been more professional and nice the two young men that came yesterday to put in our new unit Amauri and Austin were extremely professional nice and courteous from the moment they walked until the moment they left. I've had plenty of work done in my lifetime in my home and have never had such a great experience from the beginning to the end. Northside I'm not surprised you have so many stars. I will certainly recommend you to all my friends thank you for making my house more comfortable

ZERO STAR REVIEW! Had them come fix toilet that wasn't flushing on a Wednesday. He left saying it was fixed but that evening it wasn't working again. They couldn't send anyone out til Friday to look at it & he immediately said he doesn't have the tools with him to fix the clog!  
Then we hear they can't send anyone out Saturday since they're all booked. Called to complain & was routed to answering service where we were told we could receive a call Sunday. Not an appt just a call.
Holiday weekend and they may not be able to come back til following Tuesday!
Who sends a plumber out for service call without tools to fix a clogged toilet!!

I have had them out several times for plumbing and HVAC issues. They were great. Knowledgeable courteous and were able to fix everything as promised.  I signed up for their plumbing and HVAC Customer service programs. They have overcharged me every month since August. They will not return calls, emails, voice-mail to correct the situation. I understand I have to speak to Krystal but she is always in a meeting   Unfortunately I am going to have to discontinue using this company unless this is resolved.

Cornerstone may have been good at some point in the past but over the past 5 to 7 years they have become arrogant and grossly incompetent. They regularly send out techs that have little to no knowledge whatsoever. Most of the time now they do much more harm than good. They are way over priced but now seem happy to charge whatever they can get away with and joyfully gouge away with no conscience whatsoever. They send out salespeople like their son in law to play with your AC with  no idea what's going on.  They then make up stories to cover their incompetence.  Do not use them , do not trust them, believe nothing they say. You are better off throwing them off your property if you have a system still under warranty and find a competent honest company that can service your system before Cornerstone destroys it.  They have earned and deserve zero stars. Their warranties are full of wholes with bogus deductions etc. Both my son and I have fired them for cause recently . Good riddance to bad rubbish!
