"My experience with Greenwood Heating and Air Conditioning has been entirely positive. From my free estimate appointment through finished installation, the process was seamless. Each and every representative of theirs has been exceptional. Trevor negotiated a very competitive, all inclusive price for the entire system and followed up on the day of installation to see how everything was going. The install was expertly performed by an industry pro, Andril, with 17 years plus experience. Follow-up has been exceptional. Greenwood Heating has earned my unequivocal recommendation."

"The estimate and install went smoothly. Quote was very reasonable. After the install, we found that we couldn't get the heat back on. They came back and were able to trace the problem to the thermostat and gave us a new one. Am still giving them an A rating because of their responsiveness and how the install went."

"I had them install on my other house 11 years ago.. went with them again.. the people are what’s amazing.. Mathew, Bob, Jim.. Jennifer.. their customer service is beyond fantastic.. they helped us move 2 heavy plants.. that needed to be moved to put in new air conditioner.. in this day and age of automation, and messaging, they are a reminder that old fashion kindness and customer service is key to good business.. I highly recommend them.. and they configure what your house needs.. size , budget and your needs.. Mathew took 3 hrs.. of interview and measurements before offering 5 different packages of heating/cooling needs.. amazing company!!!"

"I had three estimates at our house for our conversion from a gas forced-air furnace to a heat pump/gas furnace installation.  I was most impressed by Evergreen's rep. Scott, as he was very helpful in explaining the technology and was the only one of the three to do a J load calculation on our home.  I also felt after the estimates were all given that Evergreen's was the best buy in terms of the product features vs. overall cost.   As I researched our installation I realized that my mother's all-electric home would be better served by a heat pump as well.  Again, Scott did the best job of all three estimators there as well.  

After the down payment of 50% of the cost the installation was set up within two weeks for both locations.  The work was done on time and efficiently.  My mother's job was done in a few hours, mine took a couple of days.  I'm happy to say that both units are performing perfectly, through both the colder weather of March and the warmer than usual days we've had in April.  

There were a couple of things that should be mentioned, not major issues but worth noting.  

The installation of our heat/pump and furnace did not meet City Code on the initial inspection as the condensation pump was placed on the floor.   City code required it to be 18 inches off the floor due to a potential for an explosion should there be a gas leak.  The correction was done within a few days, but I did have to schedule a city inspector on two different days.   The city inspector remarked that the installer 'should have known better'.  

On my mom's split heat pump the indoor blower unit began making a loud clanking noise one month into use.  Evergreen was quick to come out, mom called on Sunday morning and was able to have a crew come out the next day.  Apparently the installers had missed a mounting clip on the external cover of the indoor unit and over time the casing sagged enough that the rotating fans began to hit the inside of the case.  

Several weeks after our work was done I was called by the financial office asking me to pay the remaining 50% balance.  I pointed out that it had been paid on the day the work was done, but apparently the payment was not correctly registered as having been paid by their accounting office.  Fortunately I was able to point to my credit card statement indicating that the balance had been paid in full.  

Overall Evergreen did a professional job from start to finish and I have no hesitation in recommending them.  Given their expertise and experience I have no doubt that my equipment will continue to be well serviced going forward.  "

"From our meeting with the salesman through installation and charging of the air conditioner, these guys were first rate. We spent about 2.5 hours with the sales rep going over our old system, the configuration of our house, and our heating and cooling preferences before coming up with a recommended package. We purchased during the shoulder season and a crew was free the next day so BF was anxious to get that hole filled and we ended up getting a good system at a pretty fair price. The electrician was the first to arrive followed by the rest of the crew at 9:00AM. By 6:00 they were finished and they left no traces behind. Very tidy crew. Got a phone call from their scheduler the next day regarding the refrigeration inspection which they fully coordinated. Got another call from them regarding the inspector's arrival window. He had 2 minor things he wanted them to take care of which the tech who charged the A/C promptly dispatched. Every one of their staff we spoke with was happy to answer any questions we had and they were great about educating us and keeping us informed about what they were doing and why. This is the first time we've used Blue Flame and I hope they are as good with the service as they have been with the initial installation. So far, we're pretty happy campers and will definitely do business with them again."
