"very impressed----joe the estimator was very knowledgeable and not pushy-----gary the installer was super and very careful to clean up every little bit of dirt---mike who did the furnace tune was super ------------how often do you have a company so honest that when you ask to have a 20 year old furnace checked out----they do a very detailed check and show the details and they don't try to ram all sorts of repairs at you--they actually said everything is fine for now ( guess who I'll call when I need one }--they were right on par with 2 other companies I called for estimates----awesome job"

"Good price for the furnace & A/C system. Worked with my schedule for the replacement install. Techs were helpful with my questions. Would recommend Mamayek Heating & Cooling. They did a good job."

"Bob and his team were very professional. They arrived at my residence on time and spent more time than expected due to a need to replace the existing PVC venting pipe to a larger diameter. Overall I am very happy with the service performed by Bob's team. I definitely recommend his team to whoever needs heating and cooling service."

"Our nearly 40 year old boiler system had seen its last day. Steve with Guardian was easily accessible by phone, prompt, and helpful. He installed a new boiler and retooled the set up of our system. We re very happy with the service, speed of the install, and professionalism the guys showed. We didn t shop around much since we weren t interested in having too many people coming in and out of the house during the pandemic, but felt confident Steve was giving us good information and a fair price based on what we were told in the past and research we had done. I would certainly recommend Guardian to friends and family. I will update going forward if necessary since the system is currently a day old, but the house is as toasty as ever so mission accomplished thus far."

"The gentleman that came was very nice, He completed the service I requested and more. I needed my furnace cleaned and checked. He explained what he as doing and everything was great."

"Jeff responded immediately to the initial call. My work hours are not flexible and I was delighted that Jeff was willing to visit the house that very night around 6 p.m. That night, he got the dryer working temporarily until the correct part could be obtained. Returned a few days later with the replacement part and completed installation. The invoice includes parts and labor only. No flat fee for the first visit, or additional fee for locating the uncommon replacement part."

"Took awhile to get installed but did a good job at a fair price"

"Mr. Holland's was exceptional from the first phone call to followup courtesy calls after the install. They are very knowledgeable and explained all aspects of the process. There customer service, pricing and experience showed in all aspects of this project. Also they have a 10 Labor Warranty! I had a few other estimates and those companies only offer 1-3 years . So would i recommend Mr. Holland's ? A most Definite YES"

"They came out and looked over the A/C unit. I told him it makes a very loud banging when it starts up and that the company who installed it told us that was normal and it was working fine. Once he was done cleaning the unit, he went to restart it and it tripped the breaker. So he took it apart and found that when it was installed, someone had pinched a wire, cutting the insulation and causing it to short out on the frame of the A/C unit. He fixed that, reassembled the unit and restarted it. It's still a loud start, but not nearly as loud as it was. He informed me that our A/C is a builder grade model and unfortunately it's not the best on the market so it's going to be louder than we would like. Once he was done working on the A/C, he came in and took a look at our furnace to make sure it wasn't hooked up wrong also. Definitely will be calling on Faithful again."
