STAY AWAY FROM THIS COMPANY. Bob Gable was sent to us by AHS? He told AHS that the system suffered from an electrical surge. AHS denied payment. He then proposed that we contact our home insurance and they would pay for it. On the proposal he said reason for failed compressor is not known, that is after he told AHS that there was an electrical surge.

The proposal noted that he would remove old heat pump, remove existing space pac from attic, supply and install one new Rheem heat pump, supply and install one new Space Pak air handler in attic.

When he finished installing the air still was not cool. We hired an inspector who found original Space Pak unit with old A-coil disconnected and abandoned, old drain pan in place with existing unit. A new coil box had been installed on existing Space Pak unit. The electrical disconnect box was not properly installed . It was found dangling from heat pump unit and missing a strain relief on the electrical disconnect box. We had to threaten him with disputing our credit card charges. He then returned and fixed the work he had done before.

Bob was supposed to install a new drain pan. We have called him on numerous occasions to bring the pan and install it. He no longer answers his phone or email. I called AHS who in turn asked him a to deliver drain pan. As of this review we still have not received pan.

We find him to be very shifty and dishonest. Please have nothing to do with this disreputable unscrupulous Technician. He cannot be trusted. This has been going on for six months.

Please don't review this business if you received a freebie for writing this review, or if you're connected in any way to the owner or employees.

Its June, and 90 degrees out. Last night (or maybe night before) our upstairs AC system stopped working. I called maybe 10 places off of Angies List, no one could come today on a Saturday except one place that wanted to charge me $330 just to come out! Then I tried Yelp and Allied Service! They came within 2 hours, had the ladder needed to get to my roof, and solved the entire thing right away! And charged me $285, including labor and the freon fill-up. Will definitely call them in the future for our heating and cooling needs!

What a horrible experience. Bob came out and serviced my split system through AHS home insurance.

Let's forget the weeks having to deal with AHS and Bob speaking to AHS and the back and forth, that can easily be blamed on AHS... but Bob told me that he replaced a part and fixed the split system, even though it didn't seem to be working, he said give it a bit... I did, and it continued to not work... all he ended up doing was OVERFILLING and OVERCHARGING me on Freon -- the Freon then leaked out, as he never solved the problem, but he charged me for 6 pounds when the split system only takes 4.5 max.

Okay, so he didn't fix it, he lied to me, he overfilled the system, he stepped on and broke an outside light, then he completely drops off the face of the earth. I wasn't angry at this point, I frankly wasn't sure what was going on and I just wanted to get in touch with him, because my heat was not working for weeks in the dead of winter... I was asking if he could come take another look... he would not respond to phone calls or email from me or the insurance agency.

AHS eventually gave up and hired someone outside their designated companies (JC & JC HVAC Mechanical Contractors, LLC) who evaluated, fixed and properly filled the unit in a timely and professional manner.

Very, very disappointed.

(Side note: early on he was telling me that I should replace the entire unit, or tear it out and get a gas fireplace installed instead because in his opinion split systems weren't good.. well outside of a gas fireplace not providing air conditioning in the winter.. it seems like I'd be better served with a $200 repair than a $3000 replacement).

Do not use this company my mom had a boiler that was supposed to be installed last April when she went to use the heat it was not working. Called the company several times would not call back and would not return calls even hung up in our face. Called another company stated that the boiler was just set in the house and the power was supposed to be ran to it but he failed to do it and that means he did not test the system to see if it worked. He told my mother who is a senior citizen it would run fine but that was a lie. But not to call or come out to see what the problem was is just absurd also emailed the company no response he was paid in full in cash beware of half done work

Imagine this: It's Day 2 of #Snowzilla2016. You wake up in the morning and things feel a bit ... off. You roll out of bed to see the snow still falling and go downstairs for a hot cup of coffee (tea). You glance at the thermostat. You glance at the thermostat again. A third time.

WTF?!

Frantic, you run downstairs and slide open the door to look at the furnace. You're not sure what you're looking at. It's metal, boxy, and making a noise. But not the noise it usually makes when it keeps you warm. This is a different noise.

You run upstairs, even more frantically because things are getting real. Fast. You grab your phone and start Googling things. Furnace. Cold. Help. You find some numbers and call all of them. No one is helpful. Everyone sucks. You give up, turn on a space heater and settle in for what could very well be the end.

Somehow, you keep your house warm enough with the space heater and lots of cooking. Towels at the doors. Water off and pipes drained at night. Two days go by. Monday morning you call all of the HVAC people who said they'd visit on Monday. They don't remember you. Everyone sucks, again. Then, you call Bob at Allied Service Co. He comes within 3 hours, even when your street hasn't been plowed. He fixes your furnace. He only charges you a basic diagnostic fee. He shakes your hand and leaves to go save other people. You see his cape as he exits your home.

Bob is great. My HVAC/heat was not working - or so the gas company told me - and it's the day before we're expecting a huge snowstorm, so you can imagine my panic. I called Bob around 230pm and he was there by 330pm. Turns out my HVAC was fine, so the unneeded stress & expense was annoying (which I chalk up to bad luck on my part). However, I really appreciated Bob's customer service, quick turn around, and reasonable fees compared to others in the area. I had a plumber in that same morning that charged me 2-3x what Bob would have. I will absolutely be calling him first the next time I have an issue.

If I could give Bob and his company a 10-star rating, I would. I woke up at 3:30 this morning because I was very cold. I got up to check the thermostat -- way below the 60-degree mark. I pulled out the laptop and started looking for a company. When I read the reviews on Allied Service and saw they opened at 6 a.m. I decided to call as soon as they opened. I left a message at 6:00 a.m. -- Bob returned my call barely 2 minutes later. He was at my house at 8:30. My 30-year old furnace is shot, and we're expecting a blizzard tomorrow. But Bob came back with a new furnace that is being installed as I type this. And he put in a new thermostat. The other worker with him is also terrific. The price is great. As I said, if I could give 10 stars, I absolutely would. Thank you, thank you, thank you, Bob!

I can truly say that Bob of Allied Service Company goes above and beyond for his customers. I can't count the number of times that I needed either major work done right away or just something minor checked and Bob always gets the job done right! The level of customer service is beyond amazing. I can't imagine going to anyone else.

I have used Allied Service Company to service my rental properties in Bethesda and Baltimore. They are very professional, quick to respond, respectful of the tenants, and all round perfect to work with! Bob is great and the prices are very fair. When you have tenants without heat or plumbing that doesn't work, it is a nightmare - and Allied is a dream to work with!

Mr. Gable from Allied Service Co. was hired July 13th, 2015 to replace all the pipes in my house with pvc pipes. According to Mr. Gable this would stop the leaks and in increase the low water pressure thru out the house. He also was to fix the only toilet in the house.
The new pipes did not improve the water pressure in the kitchen sink and the bathroom tub pressure showed little improvement. Two tubs were left stopped up because he did not cover then up while knocking holds in the walls for the pvc pipes. In fact he didn't cover anything up. He replaced the outside faucet with a smaller cheaper one that left a gap between the fixture and the outside wall. Rain, bugs, snakes etc. can came directly into the basement thru this crack.
My major complaint with Mr. Gable is the toilet. He couldn't repair the toilet and suggested I buy another toilet from Home Depot for $88.00. I did. He said he would install it Monday July 20th at 11:00 am. Mr. Gable was a no show. To this day I have not heard from him. I rode around in my small car 3 days with a toilet on the back seat.
