We've used Bob and Allied Service to replace our AC, furnace, and water heater. They always do great work and thoroughly explain issues and option. Most recently, we were having issues with our furnace and Bob came by and figured it out very quickly and had us back up and running. They have me as a customer for life, can't recommend them enough.

Bob was great to work with. My heat pump went shortly after I bought my condo and being a new homeowner, he was very helpful in explaining to me what my options were and how to best care for my new heat pump.

In addition he made some tweaks to my thermostat the have helped my heating work perfectly ever since.

He was able to have my new heat pump installed on the roof in under 24 hours from when it broke.

Awesome service!

Robert said what he would do and charge for replacing a water heater and he actually did what he said! Same day service! He arrived on time did the job. Up front guy!

Excellent service, prompt response, reasonable prices--what more can you really want, especially when you need a boiler replaced right before cold season! Bob was super professional, courteous, and answered all my questions in a straightforward way. Work was done quickly and he followed up in the following days to make sure everything was working right. Would highly recommend Allied Service Company, without reservation. Thanks Bob!

Bob was terrific. He's a real life-saver. No-nonsense, honest, and reliable. A straight forward guy who happens to be a real professional. I lucked out with him, and would certainly recommend him for any HVAC or Furnace needs.

So happy I found Bob through Yelp! Our A/C decided to crap out, during the HOTTEST week of the year, and we immediately panicked. Called several places but they weren't available quickly enough (and one just flat out didn't show). Once I got in touch with Bob, he was able to come out immediately and diagnose the issue. Not only that, but he had the new part we needed (a fan motor) in his shop - and he came back just an hour later to install it! Now our A/C is working perfectly for a very reasonable price. Bob was quick, efficient, and knowledgeable. I also asked him about getting a new water heater, and he assessed and discussed our options for replacement, which was great. He will definitely be our guy for this stuff going forward!

Allied service company is the best!!! Our water heater broke down so I called around to get price checks, but either they were booked too full, or were way too pricey, but then I called allied!!

Immediately I could tell they were a lot more professional than most of the other places I called. They quoted me at a cheap price and sent the technician out the same day. Every dime was worth it and he was able to get everything up and running. If you need quick service for a fair price, definitely go with this terrific company!! They will not let you down and are always great with their customer service.

Bob responded in a timely manner and was able to come to my home quickly. He diagnosed the issue (at no cost) and was able to correct it right then and there. I will definitely call on him again if I have any other issues.

Robert told us we would need an all new $3500 unit. I called a second company for another opinion and they were able to repair our existing unit in an hour for $100. Filter theses reviews by worst to best. Would strongly recommend you find another repairman.
