Nimmer Heating & Air Conditioning

Actually, if it would be the negative ranking I would enter one like -10. An appointment scheduled way ahead to do the maintenance. Nobody showed up, no message was left. Took time from work to wait. NEVER HIRE THEM! Unreliable, rude, nasty, dishonest.

Asked for a quotation. Two weeks later, zero response.

Mark and his team did an excellent job from quote to finished product! 23 year old boiler needed replacement; Mark provided options and one included adding the water heater function to the boiler. We opted for that. The old boiler and water heater were removed and the new system installed. The team kept us in the loop and provided options during installation on how they would complete the job. Professional and personable team to work with. We are very pleased with the end product and would highly recommend Nimmer Heating & Air!!

The installation was more or less OK and the system performed well for about 1,5 years. However, when problems started Beth Cesar (Install Coordinator) was not helpful at all. She stated that it is not enough technichians to serve during regular hours and help is available only at the rate of late hours, which is apparantly higher. The greedeness and lack of care of the customers is really impressive. I won't recommend hiring this company. The equipment and labor are very expensive and the company motto "Care for the Customer" is just a joke. All they care about is $$$$$.

I have used Nimmer several times in the past for both heating and A/C repairs. I have been pleased with the service. So this last spring I pretty much knew the old furnace was ready to go and finally it did. Of course it went on Easter week with house guests on the way. I didnt hesitate to call Nimmer because of the past service. The only way they could get it done was to work on the Saturday before Easter for an additional $600. I agreed because I needed it done. At that time I also chose to add the 10 extended warranty for an additional $500. The total bill came to somewhere around $5400.00 Ok, Ouch! but it's the cost of living in todays world. So after time, the bill is paid and one just kind of forgets about the expenditure. But then a few weeks ago I get a letter from Nimmer telling me that I have to have annual inspections done on the furnace in order to keep the warranty in place. The cheapest inspection program is $340.00 a year for 10 years. that's another $3400 on top of the price of the furnace. My advice use Nimmer but forget the warranty

First, let me state that this review was sent and reviewed by Nimmer heating staff who had no disagreements with the content presented here. It was cold winter day at my psychotherapy office when the heat stopped functioning. Being that I was out of town, my colleague called Nimmer Heating mid-day. They said they only had "after-hour’s" appointments and would be charging the emergency rates. Given little choice due to a cold building this was agreed upon. They showed up at 5:05. They went directly down to the boiler without checking the thermostat, the thermostat being the part of the system I would have checked first had I been in town. They did a diagnostic on the boiler for $298.00. They found that everything on the boiler was working. Then, they checked the thermostat and found that it was broken. The charge for the thermostat was $512 which retails at $125. My colleague negotiated with the technician to bring the total price down by $200 to around $600. When I returned to town, concerned about the exorbitant pricing, I talked with the office staff who indicated that the rates were determined by a software program that has nationwide set prices for each service and that the charges were determined by that software. Thus, there was both the set cost for the boiler diagnostic and the separate set charge for the thermostat diagnostic and replacement. I then called the software company and learned that the only thing standardized about the software program was the time increments for each job. The rate per hour and markup on product is determined by the contractor. (So much for objective pricing.) In summary, Nimmer's charges for after-hour’s service seem extremely high and secondly, they should have investigated the more likely cause for lack of heat... the thermostat. Had they done that, the $400 for the thermostat and installation, although still high in my mind, would have been more reasonable.

Nimmer did a professional job installing our new A/C system. The entire process from Mark's estimate and final quote to the actual installation was great! Tyler and the crew were not only professional but personable as well. They kept us in the loop on everything as they proceeded and did a great job with all aspects of the work including clean up. They are a great group of guys and it was a pleasure working with them! Tyler is a definite asset to Nimmer Heating & A/C and proved to be an excellent team lead! Well done!!

Never had any problem with them. We just recommended them to our neighbors. We never have an issue where they are trying to sell us something. The repair is always minimal. They will also go the extra mile, they are honest and you know you are not going to get ripped off.

The work that was performed went well.

One person came out and it took an hour. They left the area very clean. They did what I expected.

The workers were good. Cleaned up well.

I have used Nimmer Heating and Air Conditioning in the past for the installation of our home furnace. They always do an excellent job and are professional and courteous. They provide a 10 % discount on repair services. On this job they gave me a good end of the year price for the new installations since I have done business with them in the past and because I purchased multiple products at one time. You could not ask for better customer service from this company.

The 2 guys that came out were both prompt and courteous. They spent about an hour looking around at the furnace unit and identified that the clicking sound was coming from the smart valve. They then proceeded to quote me a price of over $900 to have it replaced! That was a ludicrous amount to pay (afterwards I looked up what a new smart valve costs and it is in the neighborhood of $300. I find it hard to believe there is $600 or more worth of labor going into replacing it!) so I politely declined to have them schedule the service. I called another HVAC company and they were able to correctly identify the problem for a grand total of only $143. Turned out that when our siding was replaced, they put the exhaust pipe and intake pipe going in the wrong directions. The one that should have been pointing up was pointed down and vice versa. This was causing the smart valve to keep clicking on and off. It has been almost an entire winter now and the furnace has been working with zero problems all season long. Thank God I called for a second opinion! I would have been out the $900 and the problem still wouldn't have even been resolved! So although they were friendly to deal with, their trip charge/diagnostic fee was very reasonable, and they did provide me a free T joint for the water hose I was missing, I could not in good conscience recommend using Nimmer. Not only did they grossly misdiagnose the problem, their proposed fix was way out of line in terms of price as well.

Great.. This company and it's office personnel and technicians are very professional and helpful. I would never use anyone else!

Performed tuneup and cleaning - a bulleted list of items to check on during regular maintenance (this was the first maintenance appointment since the furnace was installed a few years ago by Nimmer). Also had them replace a very old thermostat, and also fixed some of the ducts by putting proper wiring on them to hold them up - replacing temporary 'bungee chords' that were being used. This was at my parents house, so I made sure to ask questions as needed. The service was reliable , affordable and did a great job.

I diagnosed the problem and called Nimmer.They ordered the part,came out and replaced it.Problem solved.

Our experience with Nimmer Heating and Air Conditioning started in October of 2014. We were looking to replace our 35 yr old gas hotter boiler with a new one. We received three bids from various contractors, all in the same ballpark price wise. What made us choose Nimmer was a couple of things. One was the time Mark Nimmer spent explaining the best option for our house. He really went into detail why we didn't need the highest rated boiler given the type of hot water system we had. Second, they were the only company to offer a Buderus Boiler, which through researching, I found to have very high reliability ratings. The installation was done in a very professional and neat manner. Because we have a somewhat unusual radiant hot water system ( the pipes are in the ceiling) it took a few calls to get the air out of the system and adjustments to regulate the water temp. All the service calls were responded to quickly and professionally. Very pleased with Mark and his crew. This spring we had them out to look at the AC unit as it was not starting. Mark found a loose wire, then cleaned and checked the condensing unit. He found that it needed a new capacitator which he ordered and also recommended that we replace another part that would better seal it from insects and prevent power surges from possibly burning out the unit. All services were done in a professional and timely manner.

I had a 35 year old gas furnace chugging along just fine, Over the years I had replaced every moving part on it so it was still darned reliable. It was however putting just as much heat up my chimney as into my house. It was clearly time for an upgrade. It was easy for me to call Mark Nimmer since he fixed the botched installation (Done by another contractor) of my central air unit once it was out of warranty. I told Mark that I was in no hurry and to fit me in when ever he was slow. A short time later we set-up a date and the crew of Tyler and Colin arrived right on time. They worked quickly and were clean and very well spoken. We talked through some headroom concerns I had and they were more than accommodating. The new unit is a Plus 96% two-speed system and is shockingly quiet. I got the Wi-Fi enabled Honeywell thermostat and am now very happy I did. I can honestly say that everything went great and I have nothing bad I can say about the work or the cost of the job. I am very pleased and that is rare for me. As a carpenter, I tend to be a bit of a perfectionist. I don't like other people working on my house, Mark Nimmer and his crew did an outstanding job both on the furnace install and my worries.

We've had a good experience with them. The service went well. It took them five hours to install the furnace. Their price was average. It's a "B" on price because they don't take credit.

I called and they were able to schedule it two days later. Very prompt and professional.

I was having a problem with horrible thumping noise coming from the furnace. While I wanted to wait until it was warm enough to have the air - conditioning checked with the same visit, I was afraid to let it go. When I called, they were able to put me on the schedule within a few days. The service tech (John) was on time and very professional. Turned out to be a problem because the filters were not allowing enough air flow. He did regular maintenance and I switched back to the filters I used in the past. I will certainly use them in the future.

I think that Nimmer is one of the best vendors in the Milwaukee area regardless of category. They are knowledgeable in their field, they care about what they do, they treat the customer with great respect, and this attitude carries through to the their employees. Its always a pleasure to do business with them.

JOHN WAS POLITE, PROFESSIONAL AND EFFICIENT.

Service technician Tyler did a wonderful job. He arrived on time and answered all of my questions, etc. I highly recommend this company.

Their service tech did a very thorough job of cleaning and performing other routine maintenance on our high efficiency gas furnace. Their technician took the time to explain what he had done. I would hire them again to perform this service.
