"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"Installation was quick and went well—all steps were explained clearly, and I got exactly what was promised. Great service!"

"Service was good and HVAC has been fine since."

"Kenihan replaced the piping in my laundry room due to multiple pin hole leaks. They did a great job and clean up afterwards."

"Highest ratings and respect to Air Pure. Such a professional and competent installation. I am so happy with the service and my new furnace! A purely wonderful experience. Thank you Air Pure!"

"J A Sauer has well-trained, efficient, courteous installers. They communicate well, clean up after the work, take away removed equipment, and offer maintenance advice. We have used Sauer for about four years now and have a Mitsubishi Slim system and a Carrier AC system they installed. Very happy with the work--not the least expensive, I'm sure, but fair for the quality of work and equipment they offer"

"We had both a furnace and new air conditioning unit installed. The work was top notch and we are very happy with both systems."

"The old air conditioner had finally died and needed to be replaced. The quoted price was right on the average for such a job. Not only did they get a quote to me quickly, they were able to complete the job before some others could even get me a quote. They did excellent work making the install tighter and neater than the old unit. I think the basement was cleaner after they left than it was when they started. Very happy!"

"Made an appointment  and they came when the appt was scheduled on time.  Professional and friendly explaining all condition of the furnace.  Work done promptly.  Good experience.

"I called and emailed Gravener to have the a/c fixed at my ex's house.  She rented it out and the tenants were complaining that it wasn't cooling the house adequately. 
Gravener was overwhelmed with calls due to an early heat wave, but I did get a return call from them about a week after I first called.  i was patient because I had heard great things about Gravener's professionaiism and best practices.  I also wanted to support a local business.
I talked to Terry, their scheduler, on June 3 and he set up a call for that Friday.  The tech showed up on time and was done in about 90 minutes.  I instructed them to clear any additional charges with me before proceeding, so the tech called me to let me know the system needed Freon and how much he thought it needed.  I allowed that additional expense and the system seems to be working perfectly. 
I would use Gravener for my own system and highly recommend them for others.
