I took a chance & called Armstrong after reading reviews. They came out quickly, recommended replacement & provided all information up front. They thoroughly addressed all my concerns…. they were professional, on time and treated my home like their own. I’m very satisfied"

"It would cost more to repair boiler than to buy a new water heater."

"WE WERE VERY IMPRESSED WITH CHRIS  WHEN HE CAME TO GIVE US OUR ESTIMATE.HE ANSWERED ALL OUR QUESTIONS AND WAS VERY POLITE. HE TOLD US THAT THE UNIT WOULD BE INSTALLED IN ONE DAY AND ASSURED US THAT WE WOULD BE SATISFIED WITH THE SERVICE.HE SHOWED US HOW THE HEAT PUMP COULD BE USED AS A BACKUP FOR OUR OIL HEAT.SO WE DECIDED TO GET THE HEAT PUMP INSTEAD OF GETTING JUST THE AIR CONDITIONING UNIT.THEY ARRIVED ON TIME AND INSTALLED THE UNIT THAT DAY.WE WERE VERY SATISFIED WITH THE INSTALLATION,SERVICE AND THE UNIT.

"Woke up to cold downstairs -- heating system not working.  First floor furnace was not turning on.  Called company and service technician arrived same morning.  Very professional.  Troubleshot the furnace and found burnt out ignitor.  Called Carrier to confirm part number and appropriate replacement.  Installed new ignitor and verified operation.  I also decided to purchase yearly service plan for both Heat/AC zones (two visits per year for each) for $270.

"The A/C at our rental property was running, but not keeping the house cool. I called five different A/C companies that had A ratings on Angie's list and asked how much they charged for the service fee and how much they charged per pound for R22. Three of the companies including K&J) told me their rates directly and two told me that they "bundle" the R22 cost with labor costs. I appreciated that K&J were up front with their costs and they had the best rates. The technicians showed up on time and were very professional. They immediately checked the unit outside and the air handler inside. Both were frozen up with ice. They turned off the unit and we waited for it to thaw out. While waiting the tech's (Cory and Mark) were very jovial and pleasant to talk to. Once the unit thawed out they hooked up the gages and diagnosed the problem as low refrigerant. They showed me on the gage were the correct level should be and where my unit was. They kept me informed the whole time and were very thorough. They ended up having to clean the coil in order to get the unit to take in the refrigerant. They told me the cost before they did it and asked me if I wanted them to proceed. Once the cioils were clean they added 1lb of R22 (in .5 lb increments). Then they went inside and checked the vent with a laser thermometer to make sure the temp was in the proper range. I was able to pay credit right there on the spot and they gave me a discount for using Angie's list. I would highly recommend K&J Mechanical. They did excellent work on time and at a great price. There was even a follow up call to see if I was satisfied with the service.

"They were great!! Talked to Johnathan first, told me what time he would arrive, and he was right on time. He fixed my old unit temporarily, but I decided on going ahead and getting a new unit (old one was 20+ years old). He told me what to expect for the next days installation, and it was just as he explained. They technicians were, friendly, professional and right on time. Jonathan returned, as he said he would to check on the job, and again to walk me through my new thermostat and to answer any questions. Best service ever. I'm a customer for life !! Thank you !!"

"A part had to be ordered for the repair! They keep me informed on status of part delivery and were quick to schedule time to install when part arrived! The tech explain how part work and what he was doing as he installed it! He also followed up by calling me later to check if everything was fine!"
