Callahan A/C & Heating Services

A friend recommended Callahan and I'm so glad she did! The technician came on tine and gave perfect advice and maintenance which was surprisingly reasonable. Great service.

Our boiler ignition kept restarting and we didn't know why. Called Merrimack Valley Plumbing and their tech blamed the switches and control board and wanted to replace them for a couple of grand. Callahan's techs measured air flow, troubleshooted the flue pipe, impeller, found and dislodged a blockage (burnt birds nest deep in the vent) within the hour.

Ask for Phil. Honest work for honest price. Would do business again.

The washing machine pump constantly gets clogged now all the time. The sound it makes shakes the PVC pipes and the whole house so I know it is clogged. This is also underneath my bedroom. MY GOD the sound. It is like living above a garage now.

Why did AC Callahan never tell me that moving my washing machine would entail my taking care of a washing machine pump forever (well they only last 5 years with 1 year warranty)? When the water flows, electric is right next door which is not good.

They somehow removed the pipe from inside the wall when they moved the machine, so now I need to get the wall cut open and all possibly for naught to the extent the piping leads into a dry well.

I've lived in Russia, England, Sweden and other places and never had to worry about my washing machine like this.

Why did this have to happen to me? Why would a company be so deceitful and underhanded?

They did this work March 2023. I lost my mother 3 mos later suddenly. What a year and it is still going on.

The positive reviews of this company make me sick frankly as I know what they're up to. Other providers have confirmed they are shady.

Other companies/competitors have confirmed this company just wants to milk every cent they can and leave things worse than they were before.

Had my summer a/c tune-up with Callahan A/C & tech, Daniel, was thorough in his service of our system & spent the time & effort to make sure everything was operating smoothly. He was detailed & professional. Will utilize their services again.

We had Callahan install a gas boiler about 10 years ago. We've also called them for our Central Air unit, actually 3 years ago to install a capacitor because we weren't getting any cold air. All was fine. Until today. My husband thinks the capacitor needs replacing again. The unit is not cooling the house. Could be the capacitor again, not sure, but we called Callahan for it. Well, the woman said they don't have us in their system. ??? My husband said ""I have the receipts for any work you've done at our house. She said, ""Well, we don't."" Hellooooooo???? Well, they will NEVER get our business again. Just be forewarned. Callahan A/C & Heating is not very reputable.

Callahan A/C & Heating Services installed central a/c in my home last week and my husband and I could not be happier!!! What an excellent job they did.
Matt came to our house and gave us a reasonable estimate in February and booked our job for the middle of March. Matt was extremely knowledgeable and explained everything in detail and answered all of our questions. The team of Kevin, Jason and Dan who installed our system were extremely professional. All work was completed in 2 days as promised. I was so impressed with how neat they were. They left my house spotless and you wouldn't know that they had just installed a whole new system. Callahan installed our furnace approximately 10 years ago and did an excellent job then. That was a major reason for contacting them for central air. Thanks Matt, Kevin, Jason and Dan!!! Would always recommend your company to anyone looking for HVAC services. Bring on Summer!!!!

My Central Air fan stopped working. Due to availability, it took Callahan a few days to come out, which was fine. Technician was able to come out a day early and diagnosed a bad motor. A week for parts and an hour install later and the A/C was up and running again. Communication was good, tech arrived when they said he would.

In July I called Callahan to make an appointment for an annual check of my gas-fired steam boiler, which they installed a few years ago ($7,500). I had to wait almost five months because I was told they have to honor contracts that are a priority.

Spending $7,500 doesn't make a person a priority?

The appointment was for this morning at 8:00 a.m. and when I called yesterday to confirm the woman who answered the phone (I think she's an owner) told me the technician would be late because he has to take care of his new baby.

It's great he has a new baby but why do I have to sit around waiting for him to take care of a baby? I had to get to work so I called and canceled the appointment.

This business is run for the convenience and benefit of the employees and not for the benefit of the customers. They have no shame in taking money and providing little or no service because they have no business skills and care only about themselves. Maggie and Sue answer the phone and apparently inherited the business so you know what kind of service they provide.

Go ANYWHERE but Callahan for your heating and cooling needs.

Callahan completed a full replacement of our 25+ year old home air conditioning system with a new Carrier Infinity system. Kevin who dealt with the estimate and quoting process came out as scheduled and provided a detailed quote via email within a few hours. He was also quite helpful answering questions about options we were considering and the pros/cons of each. Never felt any sales pressure either, and he honestly talked us down from pursuing a much more expensive heat pump option because the ROI wouldn't be worth it. Many other providers likely would've just taken the extra ~$7k in sales.

The install team arrived on time on the day scheduled and completed the work in approximately 4 hours, which was impressive. Everything went as planned and we're very happy with the new system. It's late October so we haven't been able to really use it beyond a quick test, but it's noticeably much quieter than our old system, and we're looking forward to the increased eco-efficiency next summer. The team also did a good job of cleaning up any mess left behind and answering any questions we had before leaving.

I'm glad we opted to go with Callahan and would definitely recommend them.

I called for replacement of expansion tank that is leaking ( a relatively easy job). When they responded they said they could not get to me til the end of the month (two weeks away)
