The capacitor on the air conditioning unit failed. I contacted Allied after hours and they called me when they opened the next morning and were able to come over in a few hours. Whittaker the technician listened to my description of the problem and was able to diagnose it immediately. He had the needed replacement part in the van and made the repair to the unit in just a few minutes. Very courteous and conscientious service. I have used Allied the last 8 years for general maintenance. This is the first repair I have had to any of my HVAC equipment. I would definitely recommend their service.

The appointment was for 8am. The tech arrived just after 9am. (Someone did call at 8:45 to say they had a breakdown.) I described the problem and he checked the fuses right away. They were obviously burnt (blackened). I had to go out, leaving my adult son at home to pay if the tech finished before I got back. I came back just as the tech was driving away; I did speak to him for a minute. He told me it was $202, that he'd been paid and that the cost (above the $90 service fee) was for parts. (I must have looked taken aback at the fee.) The invoice was not itemized, so I don't know how much the fuses cost. A search on the internet showed I could get 5 of the same type of fuses for $10 (fortunately the invoice did specify the type, as he took away the burnt fuses). I do not feel I got a fair deal here and will probably try another company next time.
Description of Work: Replaced 2 F30A 30 amp fuses.

Thank you for your business. We do value you as a customer, and are sorry that you feel you received an unfair price. Although you found the fuses on line for a lessor cost, and we wish we were able to offer repairs at that cost, please keep in mind, that the cost of running a service dept. is not just the parts involved. The cost includes time, travel, labor, parts and overhead business costs. The technician who was at your home is one of our most experienced technicians, and along with changing your fuses, he was there for a little over an hour making sure there were no other problems that would prevent your air conditioner from working. He had parts on the truck and was able to get your system up and running quickly so you were not without cooling longer than necessary. Also, we do regularly compare costs with other HVAC contractors, and we are cheaper than most. If at any time in the future, you have a heating or cooling issue and would like to have us walk you through some trouble shooting tips so you can order parts and do the repair yourself, please feel free to call our Service Dept.

We have been using Allied for 5 years. They have delivered excellent service for us for repair work on our furnace, air conditioner and humidifier. Easy to schedule appointments, quick availability, and excellent explanation of work done, work required and pricing estimates. Also used Allied for purchase and installation of new hot water heater, when our old unit ceased working and sprung a leak. Highly recommend Allied - they have always been easy to work with, communicative, and fairly priced.

Scheduling the service was very easy, Allied contacted me the next business day after I purchased the Angie's List Deal, and scheduled the service call for the same week based on my availability. Technician arrived and immediately began working on the furnace. After his work was done, he walked me through what he did and his findings. Everything was great until this point. I had a 22 year old furnace, and when I bought my home I knew that I'd have to replace it. He began the conversation about his findings by saying, "We are supposed to red-tag this machine, condemn it, and shut it off. But my company doesn't do that, we have you sign the inspection report saying you were advised of the dangers of continued operation of the machine" He then resumed professionalism and told me the Heat Exchange was showing signs of age, rings were popping off as they do overtime, and at some point could result in Carbon Monoxide Poisoning, and I should replace the furnace right away. I think his approach to "scare" me into purchasing a new furnace was inappropriate and unprofessional. Ultimately, I replaced the furnace, hot water heater, AC, and humidifier with another company.

We are very sorry that the communication between our service technician and you came across this way. The rings popping from the heat exchanger sections allows the separation of the clam shell construction of the chamber and is indeed a pathway for flue gasses to enter the airstream causing a potentially unsafe condition. With the safety of our customers being our primary concern our technicians go through annual training to be able to identify potential concerns. Over the course 46-years we have discovered that there is a fine line between the "scare" of a safety concern and the reality of the situation when it comes time to communicating safety issues on equipment. Most people do not want to hear or are at least skeptical when informed that a seemingly perfectly functioning furnace is potentially unsafe. Clearly in your situation we failed to properly walk this line and for that we apologize. We greatly appreciate your feedback, will train with this information to better our operation.

Allied is NOT honest. I would not recommend them. Please read on for detailed information. I purchased an $80 furnace cleaning and inspection at an empty house I am selling. The technician was scheduled and I could not be there during the work. The technician called me while working on it and told me my heat exchanger was cracked, that the furnace was really old, and that I needed a new furnace. I asked for a quote for both a new furnace and for repair/replacement of the heat exchanger. I was assured that I would get the information quickly. The technician did not have a new air filter for my furnace, and did not provide one - as I was told they do as part of the cleaning. While waiting for the quotes, I hired a second provider to come in and look at the furnace without telling them anything about the prior inspection. Why is ALLIED not honest? FIRST - the second contractor (25 years in business) told me that the furnace was filthy, It had not been cleaned or serviced in any way before they looked at it. SECOND - they put a camera up into the unit and inspected the heat exchanger also. They found no sign of problems, and did not recommend replacing the heat exchanger - although some other minor work needed to be done. FINALLY - I called ALLIED to ask them why their technician told me that i needed a new furnace when it clearly needed only minor repairs. Their response? "All our technicians are certified and we stand behind our diagnosis". Basically if you have an old furnace they are going to make up a story that you need a new one. They would not even explain why the unit had not been cleaned prior to inspection. How can you do a thorough inspection of a filthy furnace? ALLIED never completed the work i paid for, and then never provided me with any documentation or follow-up. Not even a receipt or inspection report. DISHONEST.
Description of Work: Provider supposedly cleaned and inspected the furnace.

I am 100% satisfied with my heating and AC system and the twice-annual service from Allied.
Description of Work: I signed up for Allied's twice-annual maintenance services to keep things in tip top shape. They are very professional and always prompt. Over the last 10 years I have had them install 2 replacements AC/furnace systems in 2 separate houses. They were never the lowest bidder, but the system is 100% carrier and their attention to detail has been amazing.

I purchased the Big Deal on Angie's List, and submitted 3 dates for service. I received the following message from Allied Air Conditioning and Heating: 10/13/2014 Thank you for your purchase. Our service department will contact you to set up your clean and check. No one ever contacted me over the last three weeks, so I contacted another HVAC company (Four Seasons) who came out and performed the work instead. I can't comment on Allied Air Conditioning & Heating's work, etc., since none was ever performed. However, I do know that we need additional HVAC services other than just a "clean and check" of the furnace, so they missed out on additional business.

Purchased service through Angie's list and scheduling was easy with a quick phone call. The lady that answered the phone was friendly and flexible to find a timeframe that works for me. On the day of service, Allied called when the technician is on his way. Anthony arrived within the timeframe, and explained the service he will perform before starting. When the job is completed, he asked if I have any questions. Furnace inspection and cleaning is straightforward but I appreciate Anthony's professionalism and there was no upselling like other providers I've used.

The technician, Whittaker arrived on time and without a doubt was one of the finest and courteous service technicians we ever had. His check of the equipment was complete and he didn't leave an ounce of dirt behind. We signed up with Allied for a yearly service contract for our two a/c's and furnances. I recommended the Allied companies service to all my family members. Being in business myself, it is refreshing to work with a service company that takes pride in their work. I would recommend Allied to anyone who wants great work at reasonable prices. I should also add that Jamie in their office was very helpful and a pleasure to deal with when first setting up our appointment.

I have a 5-Ton Carrier air conditioner and the compressor seized up late in the season. Allied quoted me a new compressor which seemed expensive but they explained that my system used an older refrigerant and it was very expensive. But I agreed. A day or two before they were to perform the work, I got a call from them indicating that they had reviewed the work order and could replace the entire condenser with a more efficient one and change the refrigerant to the newest type for slightly less than replacing just the compressor. Joe and helper came out and installed the new condenser in a few hours. It works perfectly. Thanks, Allied!
