Truly discreditable conduct by Callahan HVAC. This is our first-ever home. Never used/dealt with HVAC or basements before. Used Callahan HVAC to service our HVAC in Nov-2023. Never use our basement so in Dec-2023 when we took our guest on a house tour, we realized that basement was partly flooded. Turns out that the HVAC water condenser pump was not plugged back in by the Callahan technician when he was performing service - and this flooded our basement, rot our wood, and brought mold on wood and carpet. Informed Callahan in December and repeatedly several days and weeks but either got no response or was bumped here and there by Rick Miles, Maggie Callahan and Kate Callahan. Finally in April-2024, Kate Callahan calls me and accuses me of flooding my own basement and blaming it on them. Disgisting behaviour that I am sure they wouldn't want to be on the other end of and yet had the dishonorable act. I got everything fixed thanks to my insurance. But I have never done business with a more unethical and frankly dishonest company as Callahan HVAC is. I have every single call recording and the email chains, so I truly welcome Callahan HVAC to disprove anything I've said above.

I had dealt with them on a lot of smaller things. I'm kicking myself for not going with them for the bigger things and now I will never go to anybody else because I have nothing but great things to say about them, everybody they've always sent out. They were pretty quick to get it resolved. I haven't had any problems since.

Fantastic. The details: The original quote was for $400 more using a different device. My own research led me to a device I thought was better. They looked into and it fit the job. The device I suggested turned out to be better regarded and less expensive. Callahan reduce the quote to pass that savings on to me. They had a team of two guys that did the bulk of the installation. The team worked with me to find a location for the device and ventilation ducting. They balanced my needs, minimize disruption to basement and quiet operation, and ensuring that the installation was up to code and properly installed to be effective at ventilating the office room. I was very impressed with their attention to detail. The cuts in the wall and ceiling of my office were perfect. No extra damage to ceiling tiles or drywall were present. The duct work to the outside is very well insulated and the fit and finish is top notch. I now have fresh air in my basement office and it is wonderfully quiet. Finding a service with my level of OCD is a rare thing. I will definitely use Callahan for all my HVAC needs in the future.

People answering the phone should be more knowledgable about the services they provide. Their maintenance guys were very professional and courteous. If you are looking for a straight maintenance contract for filter changes they are suitable. Anything extra go elsewhere.
Description of Work: We had a contract with them for two years. Contract was to be renewed in 2014 and I called to find out how much it would cost to add a humidifier to the service along with cleaning out the tank. Girl who answered the phone had to put me on hold to get a price. When she returned she gave me the price for replacing the water panel. I reminded her that that was only part of my question. Said she would have a tech call me. Never called back and I never renewed the contract.

Response from CALLAHAN A/C & HEATING SERVICES
[member name removed] I want to first apologize for the customer service you received, we as a company work very hard to provide great customer service both from our office staff and our field technicians. We currently have four people answering phones who have each been with the company for many years and could answer any question you may have. Unfortunately we had hired a new office assistant in February and she must have taken your call. We realized very quickly that she was not really able to help us and is no longer working for us. Again, I apologize for your bad experience and hope you will give us another shot to make a good impression. Carol

Callahan absolutely SAVED ME from an enormous amount of heartache and expense. If I hadn’t had the wherewithal to call them when I did, it would have been an utter disaster. I tried to “save money” by having a very competent and consciences handyman look at my boiler which had suddenly stopped working. We had gotten advice over the phone from the company that installed the system and he diagnosed the issue with complete confidence as being a faulty control box. The handyman downloaded specs for a “workaround” from the Internet to override the “limit switch” that was shutting the boiler down. I was starting to get uncomfortable with this kind of and quot;improvisingand quot; and remembered the last time I had Callahan deal with an issue, they did so with complete confidence. It wasn’t cheap but he knew what he was doing and unlike the previous company, they just charged for the hours they were there with no additional fee just for coming out. I greeted the technician at the door with all my information about what I “knew” the issue to be and while I chattered away, he literally “felt” his way around the pipes. “That has nothing to do with it-here’s yer trouble right here” (pointing to a corroded valve that was clogged on the inside, preventing the water from getting where it needed to go.) Had I persisted one step more on the other (“cheaper”) path, it would have cost me over $10,000. He worked VERY diligently for four hours (I stayed out of his hair!) and at one point stopped to get me and warn me that he had to remove a pipe that was corroded enough to possibly break and if that happened it was the worst-case scenario. I braced myself and said “Okay-what am I praying for?” and Phil said “You’re praying this pipe here doesn’t break” and thankfully we BOTH said hallelujah! In the end it cost me $700 which is a WHOLE LOT BETTER than $10,000. The moral of the story is, next time, call the expert first and just let him do his thing because this is NOT HIS FIRST RODEO!

installation went fine, but some of the settings were not correct and the system has a code only for the technician, which means the tech must come down. This would be fine if the tech would answer our calls for a system not fuctioning right. We can't get some rooms to heat above 60 degrees, while others are very warm, We have a service contract and no one has responded to our calls for a tech to come dowm. After hours, when there is supposed to be emergency service, their phone just rings and rings.

Callahan responded quickly to my request for an estimate to convert my oil-fired boiler to natural gas. The sales person was very professional and knowledgeable and the company could do the work in one day with a crew of three at a time (late fall) when most companies were too busy even to respond to my questions. However, the estimate for the work ($6800) was $3,000 higher than the lowest bid from a company I trusted, so I chose not to use Callahan.

In August 2012 we hired Callahan AC and Heating to move a radiator in one of our second floor bedrooms. John was prompt, came out, did the job, and we were told that all we had to do was connect the radiator when we were ready and it would be all set. We paid $121.52 for materials and $315.00 for 3 hours of labor. Fast forward to this April, the room was finally complete and my husband connected the radiator...nothing happened so we called and asked for someone to come back out to figure out what was wrong. John came, on time, walked up and down the stairs a couple of times, called his boss (not sure why), and came to tell us that the pipe in the basement leading to this radiator was not connected. This was when we realized that apparently he had not checked to make sure the work he had done in August actually worked. If we had known that the pipe was disconnected we would have paid to him reconnect it then. Also, in August he made several trips to the basement so we do not understand why he hadn't discovered this before. I guess we were naive to think that when you hire an and quot;expertand quot;, they fully research the job and don't leave until they are sure the job is complete and properly functioning. Well, he ended up charging me $120 in labor, he charged me for a full 1hr of labor when he was here maybe 1/2 hr and DID NOT do any labor, just came out and told me that this pipe was disconnected. When I prompted him on how much it would cost to reconnect he danced around the issue and would not give me a quote, just kept saying it was easy but that he couldn't be sure how long it would take and he didn't want to give me an inaccurate quote...okay, then why was I being charged $120?? To come and tell me something you should have figured out the first time you came and did work?? My husband called to discuss the matter and we found that Mr. Callahan's customer service was just as lacking as the work his employee had done in our house. He seemed to think it was fine that we were charged for labor when no labor had taken place. When pressed about the fact that his employee had not properly tested his work to make sure that it did in fact work, he didn't seem to comprehend that this should have been done. I wished we had walked away then, but because this is our baby's nursery, my husband just wanted the work done so we had John come back the next day and for another $230 ($10 materials $220 labor!) the radiator is finally working (Oh PS, the did not refund the $120 we were charged for John and quot;showing upand quot;). This all was very disheartening because we thought we had finally found a company that we could work with. We have radiators in every room and every one of them needs to be moved/fixed, but we will never use Callahan AC and Heating again. John is very nice, but we feel this company lacks professionalism , is extremely overpriced, and they do not value their customers.

Everything went very smoothly. The crew showed up on the prescribed time and worked through the day and finished the entire job by 3:30 PM. They were prompt, courteous and worked very efficiently and removed all of the old systems plus cleaned up everything. We were very pleased with the overall installation and would highly recommend Callahan Heating and A/C!
Description of Work: We decided to replace our old, poorly performing oil fired furnace, with a new high effiency propane fired furnace and chose Callahan Heating and A/C to perform the job. We also had them upgrade our older 10 SEER Central A/C system with a new higher efficiency 16 SEER unit. At the same time we also had them replaced our 13 yr old hot water heater with a new unit.

We were referred to Callahan’s by our propane gas supplier. I researched Goodman furnaces and felt they were good quality and the sales person was ok when we met with him, so I anticipated a decent experience. While I cannot comment on the quality of the installation, (it’s June so we’re not using the furnace), I can report their work was sloppy and lacked professionalism. When I called to express my disappointment, their response was ‘we’re sorry you are not happy.” I guess they are unaware of Angie’s List. This is my first negative report about a contractor. The day of the installation, two young people a plumber, and electrician arrived. Please note - the electrician was an independent contractor. He was here for the inspection and throughout the process talked to me about what he was doing, so I don’t want this review to reflect negatively on him. The salesperson never called me during the day and there was very little communication with the workers. They packed up and left without even having me review their work. When I went downstairs, I found a difficult to close slider window wide open (because I’m not strong, I strained my back getting it to close), an extension cord left plugged in under a faucet in a sink and a file cabinet moved into the middle of our basement with its rollers removed. Now access to part of the room is blocked. Later I went out in our driveway and saw pieces of metal, sheet metal screws, and bolts strewn around in the gravel. They left without having a required plumbing inspection and told me that they would be in touch to arrange the date and time. The first inspection fell through, so they said they would call the inspector to schedule a morning inspection on a Friday and they would let me know the time of the inspection. The morning dragged on and I hadn’t heard from them, when the doorbell rang. It was the inspector, but Callahan’s never showed. The inspector reviewed the installation, asked me questions I was unable to answer, and said that he would call Callahan’s, as they had to paint the gas pipe that leads from the gas tank into the house. About 11:30 that morning, Callahan’s called me to say they were unable to arrange the inspection that day. A few days later, I’m sitting in my office and hear a noise outside. I investigate and find the plumber and another person from Callahan’s painting the pipe bright white (our house is stained grey). They told me that was the only paint they had. I told them it was not acceptable. Finally, they went out and bought some black paint, but left portions of the pipe unpainted. The inspector required them to come back and paint it. There doing that today in the rain! I've given up and will buy some paint and repaint it some sunny day.
