Gas Furnace Installation in Plymouth, MI 48170

“We first used Harriman when our previous furnace stopped functioning in cold weather in 2020. All the companies I contacted said they had no one to send for at least 24 to 48 hours. Harriman promised to send a technician within hours and they kept their word. We then used them for maintenance and eventually decided it was time to replace the old furnace. There are not enough words to describe the detailed level of service and installation of our new furnace from the point of purchase with Jon to completion of the installation. Jesse and Jeff were an amazing team of installers. They were very courteous and professional taking time to describe the process and answer all our questions. James was incredible solving a problem with the heat pump that was installed years ago by another company but would not function in the heating mode. James solved the problem and got it working. The office staff were always very friendly and responsive making sure we were kept informed of all schedules. It has truly been a great experience working with everyone at Harriman.”

“Today Mitch was out to clean my furnace which is new as it was installed in Aug 2021. Mitch got right to work and explained everything he would be doing and reviewing. I have worked with a number of HVAC companies Mitch was very comprehensive and made the appointment stress free. FYI I had Harriman out last year when the company that installed the furnace could not help me set the heat correctly. John came out and found my thermostat was never set to high efficiency by the other company after they installed it. The furnace worked well last winter after the setting was changed. I am sorry I did not have Harriman install my new Trane equipment but Happy I have found this company now.”

“I have to hand it to Jesse & Jeff… they know their stuff and do outstanding work!! Our home HVAC challenge was huge… replacing 2 A/C units and 2 furnaces with a single A/C and a single furnace… not to mention the duct work challenge of a lifetime! They took the time to help us understand everything and explain any options where we had a choice. In the end we now have a top of the line HVAC setup and couldn't be happier. Their work was top notch and we enjoyed having them in our home… even our dog Smokey loved them! We would recommend Harriman for any heating or A/C challenge.

- Celia E.

Gas Furnace Maintenance in Southfield, MI 48075

“Omigosh! Mitch was AH-Maze-Ing!

He was very friendly and handed me his card outside the front door to verify that he was from Harriman.

He thoroughly checked my furnace and changed my filter and then took a look at my other filter (that minimizes dust in my home) and advised me when to change that. He then showed me and helped to clean some of the pipes that were picking up bacteria and showed me what to do to in order to help keep it clean. He also explained some other maintenance features and in my opinion gave me a great refresher course in my furnace since it was installed about a year ago. I then stepped away and let him do his other standard maintenance work on the furnace. As I don’t know all the specifics – he seemed to do a great job.

He then recommended me getting a new water heater (admittedly, mine is pretty old) and told me what to look for as it ages to make an informed decision about when to pull the plug on getting a new one and recommended the maintenance program to show me how to get discounts and speedy service if needed. Seriously – He was excellent. Ever since I signed up with Harriman, I’ve been nothing but pleased. Kudos to you and your team and making such great hires! I am certainly a pleased customer! :-)”

“I want to say that the experience with Harriman Heating has been nothing less than outstanding. Rob and Mike were over on Monday and first let me know the procedures that were to be done. Before they started they laid tarp on the steps and through the basement. Once they got started, they went about their business. They took their time and finished about 5:00. Rob explained to me that they would be back on Wednesday to complete the job. I received a call from Emily on Tuesday asking if I could move the appointment up by one day. I advised here it would be no problem. Rob showed up and went about the business of finishing the job in a very professional manner. He had to make a few adjustments on some material that was not right. While he was doing that he took the time to answer some questions from a neighbor inquiring about possibly doing a job for her. After Rob finished he made sure everything was working and walked me through what was done and explained the filter systems and when they should be changed. He also explained that since the temperature was below 60 that it made need refrigerant later in the summer and if so, to just call the office. All in all Harriman Heating has an outstanding employee in Rob Troy. I will be calling Harriman Heating for any other mechanical or plumbing work that needs to be done.”

“The original technician who performed my routine maintenance had diagnosed a need for repair. My heat was going to be out for the night. After a call Harriman scheduled Mitch to come out the same day. Mitch was courteous and inquisitive. He heard a sound and upon investigation discovered that there was a just a bit of debris and there was no problem with the furnace! But Mitch did not stop there, he was curious about whether a nearby radon fan could be impacting airflow. Upon further investigation it was revealed that the air flow for my high efficiency furnace was being blocked outside. The other technician missed all of this. Thanks to Mitch I won’t have to spend my Christmas money on an unneeded furnace repair. Merry Christmas 😃”

“Called around when my furnace unexpectedly went out and I was unable to fix myself. Couldn’t get any other companies to come out until a week later, Harriman was able to get me in the same day. Mitch came by and diagnosed the problem and provided me with great information to make a good decision. He came back the next day and replaced the speed controller on my ECM furnace and it solved the issue! Extremely happy with his professionalism and kindness, and grateful to have heat returned to my home. He also noticed a small leak near my water heater and inspected that for me as well to make sure that everything was okay. Will definitely use Harriman again.”

“If you need service or a full equipment replacement like I got, look no further. You will not be disappointed.
My experience with Harriman Heating & Air Conditioning was by far the best I have ever had with professionals that I’ve had in my home to do work.
Jesse and Jeffrey were faced with a very challenging job and they handled it with professionalism, expertise and impressive knowledge and skills. The job was so challenging that they needed to be at my house for 4 days. Never did I feel concerned that the job would not get done to my satisfaction. They were creative and found a way to get it done, while all the time, ensuring that I was going to be happy with the choices of placement due to a very small space to work in.
Jesse and Jeffrey were so friendly and they were great sports in dealing with my puppy that was nonstop trying to steal anything they sat down for even one second (puppies LOL).
I genuinely recommend giving Harriman a try. I found the experience to be refreshing, since it is so difficult to find good professional service anymore. They were respectful, friendly, thoughtful and most importantly SKILLED.
Thank you Jesse and Jeffrey….You two are the best!!!”

Gas Furnace Repair in Wolverine Lake, MI 48390

“Today I had Technical Hot And Cold come over to get my 2014 Lennox furnace working. It took four days to get an appt. The burners wouldn’t stay lit so I had no heat. The technician did very little other than spend about 20 to 25 minutes in his van talking to somebody, then he came in and told me I needed a new heat exchanger because his carbon monoxide detector indicated that my furnace was producing more than 2000 ppm and it should only be producing 1 ppm! My son talked to him and the tech said he couldn’t tell if the heat exchanger was cracked or not because it was too complicated to see inside it. He said he could tell it was cracked because the flames shot out toward him when he turned the furnace on. He said the burners would all go off because it tripped the sensor that protected the furnace from burning the place down. My son asked if he had checked for blockages in the vents and he said no that you couldn’t get inside them to check. He did not go on the roof and take the cap off the vent pipe. In the text said it would cost over $2000 just for the labor to put in a new heat exchanger. And it would have to be ordered so I would have no heat until the end of next week. Thank goodness my son had me call Harriman!! Damon came out within 2 hours and immediately diagnosed the problem and fixed it for $200!!! He cleaned the outtake pipes with bleach and took the burners out and blew them clean. He even replaced a wire that looked suspicious. Then he showed me his CO meter registering 1 ppm. He offered to talk to my son and was absolutely wonderful and patient thru the whole process. I told him I will always ask for him in the future. What a treasure it is to find an honest company and a truly professional technician!!!!”

He spent a lot of time with us to make sure there was nothing going on with our furnace and explained everything in great detail. We are very appreciative that someone came out to take a look so quickly, and Harriman has become our new Heating & Air Conditioning company to call if needed.

“Highly recommend Harriman, and Josh Sh. specifically. Our air conditioning stopped working last night. Fortunately, Josh from Harriman, was able to come out the next day. Josh immediately knew what the problem was – the blower motor run capacitor shorted out. There weren’t any replacement capacitors available, so Josh was going to install a generic one. He kept calling around though, and found the part. He communicated throughout the process. Our air conditioning is working fine now.”

“I just purchased my condo and the a/c unit is in the storage room outside of the condo. My ac was not cooling my condo and Mitch came to do a service call. When he arrived he was extremely professional and courteous. The first thing he noticed is that the unit had a switch in the storage room that was in the off position and that was what the problem was. Once it was running he noticed and bought me outside to show me the condenser was turing itself off after a few minutes. He tested some other things and then noticed a sign on the unit door panel that the door must be on for correct meter readings and condencer operation. So he put the door back on and the problem was solved. He could have talked me into purchasing a number of things but was honest and fair. It only cost me the service fee. I would use and definitely recommend Harrimans and Mitch again. Thank you again Mitch!!”

He gave me tips, and he is truly an asset for Harriman! He not only did the maintenance on the air conditioner (which was purchased from Harriman in 2019, but answered all questions I had about a previous installment of a new hot water heater!! I feel totally confident now on what to do. Kuddo’s and praises to him, he went over and above !! Thank you so much Josh, continue doing what you do, and your positive attitude!

All declined due to cost, however, we are considering for future investments (please don’t contact us, we’ll contact you.) His assessment is that the overall R22 was a little low. But explained that could be due to the first run of the season as well as a mild day. Another option to consider increasing when we can afford it. Good Job Josh! Any misunderstanding is my own.

“Daman provided excellent service keeping my furnace cleaned and up to date. He went though my thermostat and answered every question I had about the furnace, and other service that Harriman does. He was direct and professional with all his answers. He didn’t try to push a bunch of products on me and was very kind explaining what options I had and what possible options I had for furture service. Most companies try to push a bunch of things on you and feel uncomfortable. Daman did a great job and was timely and efficient. The office gave calls to accurately tell me when the tech would arrive. Overall another great experience with this company. What sets Harriman apart from other companies is their drive to provide fast efficienct service while maintaining a very skilled, polite, and professional staff. Every time I come into an issue regards my hear and ac I know when dealing with Harriman they offer great prices and genuinely care about their customers. Have been a customer for years and every time a tech is sent out they are great and the office people are awesome at scheduling and setting reminders for serivce. Thank you Harriman for providing great service and staffing an excellent team.”

- Anita G.

Gas Furnace Maintenance in Belleville, MI 48111

“Very good service, explained what needed to be done and why.  Showed me the inside of the furnace and that even with my furnace being 10 years it was in very good shape and there should not be any problems anytime soon.  Did explain that due to the age of the furnace the parts were no longer under warranty and it was recommended that a surge protector be installed.  The power in the area does go off frequently and I never thought about putting a surge protector for a furnace but it does make sense.  John was not pushy about putting one on, explained the pros and cons and let me make up my mind.  He put one on in about 5 minutes and I do feel better about having this on the furnace.
Will call them again in a minute.”

Gas Furnace Installation in Ferndale, MI 48220

“Feel free to edit as needed. This review is for all interactions with Harriman personnel from initial service call to final installation.
John – Very impressed with how thorough this young man's inspection was and how quickly he was able to diagnose the issue. He was very polite and explained the situation thoroughly. I was glad that he uncovered the larger issues before I spent a lot of money on trying to repair a system that was truly at the end of its useful life. 27 years from a Trane XL80 is an excellent run, and it sold me on getting another Trane.
Jon – Very personable and easy to deal with. He made the purchasing decision easy, and the finance application was a snap to complete. We had an approval almost instantaneously. He set me up with a temporary furnace while my equipment was being sourced, and came back with (sorry, I don't remember who was helping that day — I want to say it was another John?) to install it. I was very happy with the speed and level of service.
Jay R. & Mike A. – I had Jay and Mike in my house for three different days, as my installation was a complete replacement of furnace, central air, air cleaner, air scrubber, and hot water tank. It also required some new ducting. These guys were very polite and respectful, always taking care to use masks (installation took place during the worst of the COVID pandemic), and they never had an idle moment — they were all business from arrival to departure each day. The new furnace is now oriented properly for easier servicing, and the entire installation was very tidy and of excellent workmanship. They also did a great job of cleaning up afterwards, and on the final day, I was given a guided tour on the different components of the new system. I have been very pleased with my experience with the Harriman company from start to finish, and I plan on having them out annually to help keep this system in tip-top shape.”
