Had my furnace checked couple of days ago and looked at by J & J heating and air conditioning. I was very surprise how proficient and professional the serviceman by the name of Jared Reynolds was. All I have to say he knew what he was doing and worked very hard. Also he was very nice and cheerful. I like that. If you need your furnace checked call on Jared Reynolds at J & J heating and ask by name. read more

This week weve been going through a heatwave and of course our AC stopped working. I Called J & J heating and air conditioning and they came to our house AFTER business hours and fixed the problem. Jerod was the specialist who did the job and he was fantastic! We highly recommend this business. read more

I called J & J to install a new central air unit in May of 2020. The technicians came out and told me that I also needed a new furnace. The furnace we had was about 10-15 years old installed by the prior owner but worked well. We never had a problem with it. They were telling me I definitely needed one and started rattling off reasons why. I was skeptical but said okay. So, I purchased both a new central air unit and a new furnace. Now here I am in Dec. 2025, and we are getting clouds of dust coming out of our furnace. The filters are caked with fine white powder. J & J are called. The techs come out and do not do a thorough inspection of the furnace, did not look at the coils. Told me I was using a pleated filter and that was the wrong kind, to use the cheap blue fiberglass one and it should be okay. Even more dust was flying out of our vents. I asked if they do vent cleaning, they said yes. They came out counted all my vents and said the office would call with an estimate. They didn't. I called another company, they came out immediately. Cleaned my vents in a professional manner. They were not furnace people so they could not tell me the origin of the dust. I called J & J again. They came out again. I asked them to look at the coil, they did with a little camera with a light, I was watching his screen as he was looking at it. My coil in my furnace was covered in white powder. I had to look it up since I do not believe these techs knew what they were looking at. The evaporator coil is covered in Aluminum Hydroxide. I am under warranty for 10 years and they are avoiding my calls daily. The owner told me I should have had the vent cleaners clean my furnace coils. I could not believe my ears. They do not have the expertise or proper tools it takes to clean the furnace coils. That is his job but he refuses to do it. In the beginning Denny the owner told me to leave my blower on all of the time, that made the dust fly all over even more, I now set it on auto. He is a scammer and will not honor the warranty he gives with the unit. My coverage is 10 years for parts and 10 years for unit replacement. He is not making any money, so he avoids my calls while we live in a dust cloud. I had to change my name in order to have him take my call and when I asked him to take care of my issue, he hung up on me. I would warn anyone who considers this company for a new furnace or central air unit, do not do it. He will leave you out in the cold. He does not care about his customers. read more

J&J heatin and cooling came out today . Was very impressed with our technician Jared was very helpful . And with the hot weather we have air again . read more

Please get other quotes before using JJ heating and cooling in Valparaiso . We used that company in the past for our hot water tank and had no issues . Called them again spoke with Denny the owner asked him cost of hot water tank he roughly gave price. We found one online same model , sz, model number it included Expansion tank as well gave that information to him he verbally honored that price. We knew that did not include labor. His team came out installed tank, Denny had his installer cross off price on statement and say that amount not correct. Gives us new price which was way higher. We asked for itemized state showing increase and was told he would get it to us.We paid which was our fault but 4 days no hot water was enough. He delayed on itemized stated when we finally got it and questioned him was told nothing he can do. Lesson learned will never use again. Sad to be dishonest to customers . read more

Just had J & J due a furnace tune up. On time professional and appropriately priced.

I have been working with J & J heating and air conditioning for several different projects. Initially, I had experienced some of the concerns others have expressed on here. However, when I started working with Jared, things completely turned around, and I found working with this company to be a more efficient and thorough process. Their prices are fair and reasonable. I would highly recommend J & J for boiler services. read more

I do not recommend using J & J Heating & Air Conditioning for any service. Short version is that the company does bad work, does not stand by their work, and cannot correctly diagnose the problem. This is the longer version. I contacted the company regarding a nonfunctioning air conditioner that turned on and blew air but not cold air. They arrived the next day. The lead technician took a look at the unit and asked how old it was (4 years, installed as part of our purchase of the home). The tech stated that the installation of the air conditioning unit did not look like it was done by a professional due to poor workmanship. He measured the amount of refrigerant in the unit and told me that the unit was almost completely empty. He said that as far as he could tell from the outside there was nothing wrong with the unit itself and that there must be a crack somewhere in the line. The tech also asked if we knew who had installed the unit. We did not. The tech told me that on a unit that was 4 years old there was no reason that the unit should be out of refrigerant and that whoever installed it had not done good work and was not a professional. The tech listed off two options moving forward and priced out each option, roughly between $1,000 and $1,200 either way, with multiple hours of work quoted and no guarantee on finding the crack in the line, as well as the possibility of additional costs due to more labor hours. I was again asked if I knew who had installed the air conditioning unit. The tech told me that I should look into whoever installed the unit and have them fix their mistakes because the price to fix it was going to be costly for me and that that would probably be the best route to take. He then mentioned that J and J installed Goodman brand units and wondered if it was them. He assured me that they would not have done such poor work and that they would not have installed the unit the way it was if they had done it, and would have done a few other things differently. He assured me that if J and J had installed it, it would be a different matter regarding cost because it would be their fault. He also asked if we had had any AC repair work done or other repairs to the air system, which I answered no except for the cleaning of a dirty flame sensor in the furnace. He then continued and asked me to wait while he called to see if J and J had installed the air conditioning unit. After checking with their office, the lead tech told me that according to the records J and J were the ones who did the installation of the unit, but the company would not be covering anything regarding the cost of repairs, as it was out of warranty. I would have to pay the roughly $1,000.00 to have it repaired at a minimum. He stated that the unit had been working for 3 years without a problem so it couldn't be their fault. The lead tech repeated over and over that he was sorry about the situation but that he was just the messenger, but he would get started right away filling the system with the refrigerant and dye that day and we could run the system and they'd be back in a week to check it out. I politely refused, paid the service fee, and contacted someone else. Why I would pay someone to fix their own bad work is beyond me. The upside to this situation is that I got in touch with a much better local company who came out and didn't have to rely filling the system with dye or doing soap bubble tests with nitrogen for hours on end, because they actually had tools to detect refrigerant leaks in the system. As it turns out, J and J had done a poor job on the installation, not just because they did a poor job sealing the line coming into the house, or running it to the furnace, or letting old equipment hang off the new unit instead of being removed, but because the evaporator coil in the furnace was already at its end of life when the new AC unit had been installed. That was the actual source of the refrigerant leak, which the company I did end up going with did not even need to take 2 seconds to look at to figure out that was the problem. It was a rusted discolored mess, and the refrigerant detector went off immediately when probed. When J and J had come to our house to diagnose the problem, they did not look at the evaporator coils at all. They glanced at the furnace, glanced at the line downstairs, checked our thermostat and then went outside to tell us there had to be a crack in the line because of the lack of refrigerant. They repeatedly tried to push back on us that we had somehow messed something up by doing our own repairs, trash talked their own work, told us they'd stand by their work, reneged on that promise, then tried to stick us with the bill for a problem that turned out wasn't even the problem but would have been plain to see if they had done a cursory review of the entire system. Go with someone else besides J and J. read more

I have had Denny and his men for work in my former home. I have had the entire HVAC system and AC in that home replaced throughout our 20 years there. They were consistently on time, great attitude and professional work, experts at their work and their bids were lower than any others. They ended up replacing my hot water heater at that same residence after was told by another company they would have to knock out a wall, etc. They came in with a lower bid, smaller unit the next day due to our time concerns. Fantastic!! Now in our "new" older home, they have already put in duct work and recently a new A/C unit. The old one was dangerous and not functional. Again underbidding two other estimates. They are fantastic! We recommend them to anyone looking for HVAC, plumbing or other concerns such as these! Thanks Guys!! read more

I highly recommend J&J for all your heating needs. I had this humming for awhile when the furnace was running. They came out , spent a lot of time trying to figure it out and they did! They were relentless on figuring it out and I am truly grateful. read more

Could not be more upset...I had a service tech here for over 2 hours-complete waste of my time!!! I needed him to help me understand which vents off the furnace to open and shut to make our air flow more economical. In the summer our upstairs was hot, not much air flow from any vents, while the main floor and finished basement were cold-all floor vents being shut except for upstairs. Basically he told me he could not figure it out even after calling his boss. His recommendation was to keep all furnace vents open and shut all floor vents off besides upstairs. So 2 hours of wasted time, all to tell me there is nothing better he could offer-same settings as I had done already. They then tried to bill me for that extra time when I called to get a quote a week prior stating it was going to be $87. Needless to say I did NOT pay for the other 2 hours, just $87. read more

I can't imagine a worse experience. The furnace they sold me broke more than 10 times in 5 years. I finally gave up on them being able to make good on the money I spent. Stay away from this company unless you have money to throw away. read more

I was assigned to J & J by Nipsco ESP/Pivotal to do what ended up being significant repairs on my gas lines and furnace. Denny, the owner, bent over backwards to get all of the work covered and did a great job! If you have had to deal with dishonest Pivotal contractors, as I have several times, then you will appreciate these guys. I know I will ALWAYS ask for them to do my repairs. Their crews spent a couple of days repairing multiple gas line issues and then repaired my furnace (which had been deliberately sabotaged by a very dishonest Pivotal contractor). When Pivotal didn't want to pay for all the work, they went to bat for me and got it all covered. All of the employees I dealt with were honest, considerate, and went out of their way to make a horrible situation right. These are the first, and only, contractors that Pivotal has ever sent into my home who were honest! I will use them again and would recommend them to anyone I know. Thanks J & J! read more

The most poorly run business I have ever encountered. I called them to do the annual service on my furnace. Arriving at the house, within 5 minutes they were telling me that they could not do the work as my furnace has a cracked heat exchange and needs replaced. I informed the service man that I was selling the house and need a quote ASAP for the furnace. He took the information and said the owner would call later on today. I received no call, so the next day I decided to call other heating services. I never received a call from J&J. 12 days later I received a quote in the mail offering different alternatives, but no call to explain the options. 3 days later I received a call regarding the offer. Informed the caller of my experience and that I had taken my business elsewhere. A month later I get a bill for an hours work and servicing my furnace, of which neither was completed. My opinion isTake your business elsewhere. read more

They were great at first. I had no heat and they brought me space heaters to keep us warm until we could afford the replacement. They came and put in the new one...but didn't finish the duct work , take away my old one, nor did they take their space heaters back, left a bucket of things in my basement, and only gave me a cheapy filter instead of my extra thick super expensive filter I paid for. I was told they would come back in a week or so to finish. Its been 3 months. I called and was told they would call me back right away after they talked to the owner to schedule. No call. I am irritated and wonder if my $100 increase in my electric/gas bill is because things were not finished. read more

I called a technician to come over a weekend to evaluate our furnace because it wasn't firing properly. After not really looking at it, he suggested that we have both of our furnace serviced during the week. They came back on a monday and without really looking at anything, said that I needed to have both our furnaces replaced. I called Maglish and they actually evaluated the furnace and told me that all I needed to replace was an electrical board. They actually laughed at the idea of replacing the furnace. Don't call these people to service your furnace. Call Maglish instead. read more
