He even stated "this will fix the problem." Well, guess what...it didn't fix the problem. I paid all that money for a repair that I was assured would fix the problem and got nothing to show for it. No offer of any type of refund for the ineffectiveness of their service...they came out once or twice more but didn't do ANYTHING to remedy the issue. So I was left paying for a repair that either wasn't needed in the first place or didn't fix the problem they assured me it would. The last guy that came out (apparently one of the owners) was very snippy and sarcastic about the situation as well. I wouldn't recommend these guys to anyone since they bilked me out of thousands.

Customers of ALL HVAC companies beware: First, let me…read morepreface this review with a little background. I have been in the HVAC industry for 38 years, and five of the best of them was as an employee of Haller Enterprises. I respected the company so much that I maintained a service agreement for my system throughout my stent with other employers. They have crushed that loyalty. I will also say that there are 'bad actors' in all businesses, and an employer may not be able to 'weed them out' until it is too late. However, it is how the company responds, when an incident occurs, that 'makes or breaks' the quality and standing of that company. On December 4th, 2025, a service tech from Haller Enterprises, Inc arrived for my annual heater service. After a short time with the furnace, he came up and explained that the furnace had a cracked heat exchanger, showing me a picture of said crack on his ipad. He stated that he had to, by law, turn off the system, and the oil supply to it, and "red-tag"ed the unit as 'dangerous or deadly' to operate. I replaced the unit using another company. The owner and installer of the new unit stated that upon removal, he found no crack in the exchanger. I had another tech and friend come out to inspect it with the same determination. (At a later date, Haller sent their own tech to inspect the exchanger, again with the same conclusion. They also requested that they 'take' the exchanger back to the office for a more thorough inspection. I refused that request as I felt at that time, it would become evidence, and I did not want it to accidentally disappear.) I then contacted Haller Enterprises with this information and asked how they would like to proceed with the matter of my replacing a piece of equipment that did not need replacing. I was promised a quick response and received none. I then made another seven contacts with management to amicably resolve this matter. Each time I was told that they would respond either in a day, or on a Friday, responding on the following Monday. Each time, I received no follow-up. So, unfortunately, I must resort to letting the judicial system settle the matter.

Caleb Groff showed up four days later right on time. During service he kept us appraised of his progress and answered my questions while he was working. Caleb was friendly, personable, patient and professional while doing the service. Afterward he stood in our kitchen and went over everything he did, what he found and how the HVAC was performing. He did a fantastic job! Excellent service. After Caleb left we received and detailed report of all service that was done and the condition of our HVAC system. We have a service contract. This cost us $98. A great value.

They were on time, checked out the AC, added coolant and then took a quick peek at the furnace. They said both look good for the age (17 years) and should be good for a while. I had questions about rebates for heat pumps and he had answers about rebates, rough costs and advantages of the new heat pumps. He reiterated that we didn't need to change out our current equipment but if we feel it's important for environmental reasons there are good options. We'll definitely be using them going forward, and have a fall furnace checkup scheduled.

Last cooling season he…read moresaid the outside unit was near the end of its life, the unit was in the house when purchased. It''s a rental when it dies, we'll replace it. On the first cold day this winter he claims the heater is all rusted out in the exchanger and has to be replaced, along with the entire system because a new heater can't work with an old air conditioner. Our neighbor suggested we call their guy. He's been in business for 30 years. Needless to say, the heater was not rusted he showed me the unit was very dirty, the fan motor and wheel were clogged with dirt and there were two dead birds in the chimney. The outside air conditioner was only 10 years old. I'm convinced SK had never done anything other than collect their fee and try to sell stuff we didn't want or need.
