"He showed up in a timely manner. He did the job quickly. There was a shorted wire that he had to re-run and pull through the existing pipe. So far it's all working great and has not needed to return. So far everything working great."

"Unbelievable! Beyond impressed with quality of service, and the technician that arrived, very punctually was very knowledgeable and polite. Being a homeowner for approximately 10 years, I have dealt with quite an assortment of contractors. Mr. Handyman has gained my trust after this experience, especially after calling multiple contractors with a state of urgency, all of whom replied they "may be able to get someone out next week"... Mr. Handyman dispatched a tech the next day! I will not hesitate to call again, THANK YOU!!!"

"Chip (aka Bob) Newren came out and gave us an estimate based on our home being approximately 2000 square feet. He gave us 2 options, the package we chose listed above, or  for about $2000 more we could have gotten a 95% efficient heater and SEER 16 AC.
After reviewing the government sites, that $2000 would take 11 years to recoup - so we went with the more basic package.
The installation was set up 3 days later. The install crew were informative, efficient and just a pleasure to be around. The install takes all day so this is not a small matter. It turned out that Chip had measured incorrectly and the heater we chose would not fit. They decided to upgrade our heater to a version that WOULD fit properly at no extra cost.
This is above and beyond - the stand by the estimate and didn't try to up-sell me once my decision was made. All around, it was a great experience. This company absolutely kills it with their customer service and honesty. We no longet do business with anyone else regarding plumbing, heating and air. 
Do yourself a favor and call Chip.

"Hansen Bros did a beautiful and wonderful job. Very professional, very clean (they protected the plants, sidewalk and bricks all around the job.) Great communication about when they would be showing up (as weather for an outside job can make a big difference)...and they showed up on time, performed outstanding work and their pricing for the whole job was very fair and reasonable. They even washed the windows on the outside. I will definitely be hiring them again for any paint work I need done. I highly recommend Hansen Bros.!"
