"Very pleased working with Adams Heating and Cooling. They installed a new central air conditioner system from Rheem. Everyone I spoke with from Amber and Gene in the office, Terry in Sales, and Joey R and Alvin with the installation were friendly and professional."

Customers say: True professional

"We had a new furnace combi installed in our basement and We were exceptionally impressed with Kevin and Aaron and the 2 other gentlemen who helped. They were considerate and cleaned up after each work day. We engaged in a little conversation and both these guys were so nice! They went out of their way to do things right."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"I needed an electrician to install a 240 volt outlet quickly for an electric dryer coming on Monday. And didn’t know who to use, so went on Angie's List and found Ohms Electrical Services, who responded back within a few hours of calling and was able to come the next day. Lloyd was the electrician, who came and did a great job. He knows his stuff and if very personable and professional. He also saw work a past electrician had done that was not to code and explained why and that is was a safety issue, so will be having him back soon to fix that as well as other projects. Definitely, would recommend and very reasonable price."

"North Country PHC was a great choice for me.  You should consider it, too.
After the first winter in my recently purchased 1870's vintage house, it was clear that the patchworked heating system, aging and inefficient, was a big problem.  Upstairs had circulating hot water, poorly installed.  Downstairs had old electric baseboards.  There are no ducts anywhere in the house.  What to do?  Call experts!  Several 'experts' then made proposals that fell short in a variety of ways.  
I met Matthew and Karlene Gucker, the owners of North Country PHC, at a home show.  They listened and told me they very much wanted an opportunity to make a proposal.  They followed up in writing to underscore their interest in my job.  As I had liked them immediately, I made an appointment and hoped they would deliver a quality proposal.  
Matthew arrived at the appointed time, toured my house, listened carefully to my goals, took his time and made careful notes.  Before departing, he told me in detail how he would address the problems I had identified, showed me some problems I had not seen with my inexperienced eye, and explained how he would address all my goals for this big job.  He even significantly reduced the cost of the job by salvaging the hot water circulating system by correcting the offending plumbing problems in its installation.  His was, by far, the best response I had received.  
He quickly followed up with a detailed written proposal that outlined the work, the equipment, the time frame and a meaningful breakdown of the costs.  
North Country removed one decrepit boiler and two very old gas water heaters.  In their place, I received one modern energy efficient combination boiler that heats the entire house, as well as provides potable hot water.  The upstairs hot water circulating system now works perfectly.  The old, offending plumbing that held it together is gone and new, properly installed plumbing has  it all working like a dream.  Downstairs, the house is heated by a radiant system that was readily installed from the basement.  The house is warm.  The boiler is silent and costs less than its predecessor to operate.  I have all the hot water I can use.  Mission Accomplished!
During the installation, one of the company's crew members was hospitalized.  No one could reasonably foresee this would happen.  Matthew and Karlene immediately informed me and ensured that it created no greater delay in my job than was absolutely unavoidable.  The communication from them both was excellent and the inconvenience to me was almost non-existent. They made sure I was never without heat or hot water.  The entire delay lasted no more than a few days.  For me, it amounted to no problem at all, but only because of the pro-active response from Matthew and Karlene.  This could happen to any employer at any time, but not all of them would handle it as well as North Country did.  Their attentiveness to the matter was excellent and much appreciated.
I always felt I was in good hands during this large job. My confidence never wavered that I was getting a great result.  I was rarely without heat or hot water, and then only for a matter of a few hours when essential, relevant work was being performed.  
I subsequently had other contractors in the house to perform some work unrelated to the heating upgrade.  I had to nudge them away from their enthusiastic examination of the work Matthew had done.  They were greatly impressed.  When the inspector from the local department of buildings came to review the finished work, he was also most enthusiastic about it.  He told me, "I never see work this good.  You got great work done here."  
Matthew has been back twice, at no cost to me, to check the work and make some small adjustments.  I don't know how this job could have been better.  Thank you, Matthew.  Thank you, Karlene.  
If you have plumbing or heating work to do, Matthew Gucker's expert input should be sought and carefully considered.  North Country PHC delivers.
