Mike Had Greg and crew do a lot for us which included a power panel upgrade with lots of extras then after talking to Greg Granger we agreed on a HVAC replacement that included everything as our old system came over on the Mayflower. Now we are way more comfortable in our home and saving buckets of money each month mainly due to the efficiency of the new 20 SEER Bosch HVAC system. I can hardly wait to see if Granger goes into the solar business. They are my go to guys!
Luis was fantastic--knowledgeable, helpful, friendly, and totally great. I'll be requesting him each time from now on. I'm so glad that the change in name hasn't affected the service here!
Luis Mark's consult for plumbing our bath remodel was excellent, very helpful. We await an estimate from Mark's supervisor regarding adding a short branch duct to deliver AC to the master bathroom.
Mark Really appreciated a call to come today instead of the scheduled time for Tuesday. We really like the great service.
David Mark came onsite to consult on 3 phases of plumbing for our master bathrm remodel. Aldo had provided a high level estimate, and Mark looked at the detail of job by phase. Both techs Excellent. Also Mark looked at our opportunity for additional duct to bathroom while walls open, so he can relay to supervisor for assessment. Appreciated!
Mark Mike did a great job, professional, courteous and great personality. Please tell him he left his shirt. It is laundered and waiting for him.
Mike Mike was great! He insured we knew how to operate our new faucet and answered all of our questions.
Mike Honest and professional technicians. Reasonable and competitive prices for plumbing and electrical services. Keep up the good reputation.
The visit today was for an estimate of heating/cooling system. Chad was very knowledgeable. He was able to answer our questions and more. Very impressed with the information we learned and helpful for our decision making.
Not ready for generator installation due planning and equipment purchase. I am getting ready for a possible installation of equipment in the next year.
Have contracted with Granger A1 Service Heros for 9 years for maintenence of AC, water heater and electrical. They are professional and efficient. Highly recommend their service.
outstanding company - great crew. prompt, efficient, and very competitive. this is not your average company. i am very pleased. would recommend to anyone.
Mike came out to do a consultation only 2 hours after my call to have service. He was very professional and extremely knowledgeable. He quoted me on the spot for a new tankless water heater installation. After I agreed and signed electronically he began working to remove the old water heater. He then went to get the new tankless water heater from the warehouse. When Mike returned he arrived with Mark (very professional and extremely knowledgeable) they were efficient and work with extreme precision on their installation. They were very kind and had detailed explanations to all of my questions. I would highly recommend their service. I couldnt have ask for more. Thank you Mike and Mark!
David and his assistant were very professional in performing the maintenance on our A/C. Highly recommend this company.
Danny has been here for several things. I couldnt be happier with his knowledge, work or professionalism.
Chad Beckstrand was super. He explained everything clearly and was responsive to our questions. We look forward to working with him on both projects.
Daniel and Giovanni arrived on time and got started. I had a notion of what I needed done, but they assessed my job and did what was needed and did not upcharge me like some places might. I really appreciated their approach to the electrical work they did. They cleaned up after doing the work, and didnt disrupt my work day. I asked about other electrical work that I want done around my home, and am looking forward to a quote for these jobs too. They even took care of a little job I needed help with that was not part of my original call. The added bonus with A-1 Service Heroes is that they also do AC/Heating service and other jobs as well. I also had my system serviced for the winter and got on the bi-annual contract coverage that I normally do when I move into a new place. I highly recommend them for any jobs you might have. Everything is done right and I feel like they heard my needs and answered every one. Thanks Daniel and Giovanni for a job well done!
