He then did a complete inspection of the plumbing in both units of my duplex. Wow. Service like this is simply outstanding.

I had to have a new furnace installed and it was under a home warranty program that I had and…read morewasn't really 100% confident with the choices that the warranty program suggested that I reach out to. Turns out that first call heating has a stellar crew and I am extremely happy with the work they did and the patience they had with my concerns. I haven't had to deal with new furnaces for a long time so they definitely did a good job on that. I don't know how they price compared to other shops because that's not something that you can really just look up or call and ask. After having a brief conversation with the owner on one of the issues I was facing concerning the warranty company he took the time to really break it down for me as to how they work and that my warranty company was the one that he chose to stay with. Over the years, he used to have a few others, but apparently they did not serve the customer very well (and them). I had a Lennox Elite installed and it's definitely a nice furnace...I just hope that it outlast the other brands out there. The warranty on parts and labor seem to be pretty comprehensive. What is also nice to know is that with first call heating and cooling, they have a very nice 100% satisfaction guarantee for the first year. The way that it was explained to me was if anything goes wrong at all, I don't pay a dime and they come out and fix the issue should there be one. I'll wrap this up by saying that when the crew comes out to your house to do an install, they are extremely polite, kind and very conscientious of what they're doing. I would highly recommend first call heating and cooling without a doubt.

I decided to go with Herchenbach Mechanical after comparing a couple other places in the area. Scheduling an appointment was easy. Curtis and his team came over and installed the AC unit fairly quickly. They were very professional and courteous. Fast forward to a few days ago, my kid decided to throw pieces of chalk down the pipes. I called Herchenbach Mechanical to schedule a time and date that works for me. They will email and text you to confirm your appointment. On the day of your appointment, they will also send you a photo of the technician that will be over. Adam, the technician, was very friendly, knowledgeable, respectful and on time. I told him what happened and he explained what he would need to do to get the chalk out from the pipes. I also scheduled them to clean my AC as well. After Adam finished using the hose from the backyard, everything was neatly put back the way it was. He didn't leave anything out or left a mess. When he was inside the house, he would immediately put on those disposable shoe covers without me having to ask. Herchenbach Mechanical has always provided great, friendly service when I needed them. I have nothing but good things to say about Curtis and his team. Again, highly recommend them! You won't be disappointed.

In December 2025, I purchased a new furnace and condensation pump from this company for over $4,000. Just a short time later, the condensation pump stopped pumping water properly. I contacted Heating and Cooling Solutions, and they sent a technician to my home. The technician determined that the plastic drain tube they had originally installed was too long. They simply cut the tube shorter to correct the problem. Despite this being an issue with their original installation, I was charged a $129 service call fee plus an additional $150 for approximately 15 minutes of work. I called the owner, Todd, to ask why this repair wasn't covered under the warranty, especially since the condensation pump had just been installed by their company. Instead of standing behind their work, I was told that I should have been performing "preventive maintenance." I find it unacceptable to be charged nearly $300 to correct what appears to have been an installation issue. A company that installs equipment should stand behind its workmanship, especially on a recently installed system. Instead, I was left feeling like my concerns were dismissed and that I was being charged for their mistake. This experience has left me completely disappointed. I expected much better customer service and integrity after spending thousands of dollars with this company. Unfortunately, I feel these business practices are unfair, and I will not be using or reccomending Heating and Cooling Solutions again.

No complaints at all about the techs or their work. All in, these guys are great overall. Their techs are great, the communication is great, and the heat runs like new. I will be going back to them time and again.

I set up an appointment with this company for my shop units. I was use to going to Stop Heating &…read moreCooling and was told they had bought them out. I explained that I had an air conditioner/hearting unit that needed help. I explained that the unit was smelling of vinegar and moldy smell. I explained that the unit was cooling but that it was extremely hot to the touch outside. I was told that it was most likely a valve that was plugged and that they could come out and fix that and clean the unit. I set up my appointment for 3:00. The next day I called and asked if I could have both units cleaned so I would be set for winter. I again explained that these were hear and air units AND gave them the name of the unit I had in my shop. I was told they could do that. They did ask if they could back the appointment up to 1:30 and I agreed. On that day I get a call at 11:50 that Mr. Michael Gaughan is on their way. I race over there and open up my shop. I am waiting for 20 minutes so I call to make sure they did not come early and leave. The person on the phone tells me they are still on their way. Ten minutes later I get a call from Mr. Gaughan from his vehicle asking me if I am there even though he parked right in front of the shop and could clearly see me inside the building. He walked in and I proceeded to show him where the units where and what was happening. He cut off my sentence by wanting to see where they were in back. We walked around the building and he looks at the one unit and asks me if the unit is working and I said yes, but it is running really hot. I told him that the company thought it was something plugged. He then asks me if water comes out of the unit. I said I did not know for sure because se there has been no water coming out of it. He then asks me why I would think water would be coming out and I said because the condensation has to go somewhere and its clearly standing water inside. He then asks me where the water is. And I have no idea what he is talking about. And he said well the water to hook up a hose. And I said, we do not have water back here. It is in front of the building. Is this so you can clean the unit or what because your company never said anything about this. So he then starts walking the opposite way of where we came in. Not to look at the other unit but just walks away from me. I ask him what he is doing and that there are no water outlets over there. He proceeds to tell me that he is nosy and he just likes to nose around and see what's going on. I tell him that where the trash is and it's easier to get back the way we came. On the way back I show him where the water hoses are and he complains that his hose may not go back that far. Back in the shop, he then turns to me and asks me what he wants me to do? Does he want me to take the unit out? Does he want me to take all the insulation out? How the heck do I know? I called his company and they told me they would clean the unit and fix the draining issue. They never asked me any questions. So finally I ask him if he has ever seen a unit like this. And he tells me he only works on big units and split units. I ask him if he knows what to do because if he is not comfortable doing this I cannot afford to have him mess it up and need a new unit. And he still has never even looked at the other unit. So then He starts complaining about how he would have to do this and I have now lost confidence in this guy. So I call his company back and tell them that this guy is not sure how to proceed and could you talk to him. I am now in business mode voice stating that I told you everything when I made the appointment and now I have someone who I am worried is going to screw things up worse. So I give Mr. Gaughan my phone and they discuss it. He hands the phone back to me and the they tell me that he knows what to do and it will be okay. I again reiterate that if he does not feel confident doing this I cannot afford to buy another AC. So I get off the phone and say you are good to go. But by that time Mr. Gaughan has developed an attitude. He takes two steps and gives me the stink eye. Takes two more steps and gives me the stink eye. He then takes out the filter to the AC which is clean and then shoves it back into the unit. He tries to pull the front plate off of the unit and cannot and clearly does not know what he is doing. I then say to him; I do not understand what is the attitude here. Look, if I am not confident in my job, I let the client know so they do not walk out unhappy. Do you feel comfortable in what you are doing? He turns to me glaring. I am looking back at me and he starts walking past the door and takes two steps and says angrily Competent and then walks some more and says competent. And I say back to him, I have no idea what is going on here or what you mean by this. He then walks around his truck and stands there doing nothing and then he walks over to the other side

Active Heating & Cooling came today because of a very loud buzzing noise coming from our Furnace…read more We selected Active because of their 5-star rating. Alan came today from Active and after troubleshooting the Furnace it was determined that the very loud buzzing noise was being created by too large of a filter, which was completely the wrong size and much too thick, which was causing the motor to overheat and causing the very loud buzzing. My neighbor installed the filter two weeks ago and installed the wrong size. Active Heating & Cooling solved the issue in 15 minutes today and did not even accept a service charge. The entire service call and solving the issue was done completely for free. They said they want long-term relationships and referrals and are not about making a quick buck. This type of honesty is rarely ever seen, and Active Heating & Cooling is as honest and as professional as we have ever seen. Thank You Active Heating & Cooling!
