Everything went well. They did what they were supposed to do. They cleaned out the furnace and got it winterized. They did a good job.
Description of Work: They did a furnace tune-up this past fall.

This job took about 4-5 days to complete. The technicians were professional and cleaned up after themselves. Wasn't informed that all of the old metal duct work was being replaced by round flexible duct work. New Rinnai tank-less hot water heater required a one inch gas line, but National Refrigeration installed a smaller diameter gas line that was not recommended by the manufacturer. In the process of relocating my furnace, technician broke the UV bulb that was installed in the old duct work and didn't own up to it. Never told me that it was broke. Upon relocating my main return vent on the main floor, installer didn't inform me that I would have a noise issue because the main return vent was much closer to the furnace then previously. When my HVAC system is in Stage 2 for cooling or heating, the noise from the newly relocated vent interferes with the home theater. As experts in their field, they should have informed me that the relocation of the main return vent would generate excessive noise and maybe we could have found another location for the main return vent. But instead they told me that they never heard my HVAC system before they worked on it so they don't know how much noise or lack of noise that it generated. Warning: If you have work done on your HVAC system...ensure the people that work on it know what works and what doesn't and when it comes to noise from your duct work...ensure they hear your system run before they do any major changes...otherwise they will say they don't know and blame you. Also, in relocating my furnace and installing new duct work, they blocked the gas shut off valve for my gas fireplace. I called the plumbing inspector for the city and after his inspection, he sent National Refrigeration a letter to make the gas shut off valve for the fireplace accessible, repair the UV light that the installed incorrectly (that's how the UV bulb broke) and to install the proper size gas-line for the Rinnai tank-less hot water heater so that it is within code and complies with Rinnai's installation procedure. I've had multiple gas leaks and strange odors after they completed their work and they assured me that everything was ok. I called them the next day and complained about a strange odor in the basement...when they came out several times for this, they kept telling me that did not smell anything. I had a friend come over and he could smell a strange odor like something was burning, but National Refrigeration technicians kept denying that they could not smell anything. I would check my gas meter and I could tell with no gas appliances in operation, the meter was still registering that I was using gas. I called the plumbing inspector again and he said I need to contact the gas company. The gas company came out and found excessive gas was leaking and shut the gas off to my house. National Refrigeration sent a technician to repair the gas leak. After the technician was done he said there are no more gas leaks. The gas company came out and turned the gas on. After a few days I thought I could smell gas again, I call National Refrigeration about the gas leaks and they came out and said there were no gas leaks. After I few months had gone by, I guess when you smell gas for awhile your senses get adjusted to it. My neighbor called the gas company cause she could smell gas in her basement (I live in a townhome). They inspected her house and came to my home and found out I still had a bad gas leak and they shut my gas off again. I called National Refrigeration and their technicians came out and also found the gas leak and fixed it (so they say). Before the technicians left, I called the gas company and they sent their technician out and he checked their work after they told both of us that there was no longer a gas leak. The gas company checked their work and still found gas leaking. The National Refrigeration technicians attempted to repair the gas leak again but were unable. The gas company technician told the National Refrigeration technicians that he would repair the gas leak for them...which he did. Now I do not have any more gas leaking into my home. I still have to deal with excessive vent noise from the new main return vent that was installed. I have found that National Refrigeration tried to take short cuts and save money for themselves by installing a lot of flexible duct work instead of insulated metal duct work, they used a smaller diameter gas line to the hot water heater because the 1 inch gas line was more expensive. I also found incompetence for something as serious as gas leaks that they were given multiple opportunities to correct but didn't. I also found their lack of honesty when they accidentally broke the UV bulb during the furnace relocation and didn't notify me and when they kept coming out telling me they don't smell anything. Make sure you have a family member, friend or neighbor with you when people come to work on your home.
Description of Work: Relocate furnace in basement, remove old duct work and install new duct work above ceiling, also install additional duct work vents and return in basement. Relocate main return duct on main floor. Remove old hot water heater from the rear of the basement and install a brand new Rinnai tank-less hot water heater to the front of the basement (required a long gas line and new venting)

First call went to their answering service. It took a while for a call back but the person on call did agree to come take a look. By the time he arrived, the furnace had spontaneously started up again. The furnace had a flashing light feature to help guide the repairman (or homeowner) to where the malfunction lay (color and number of flashes points to problem site). I had noted the light flashing pattern while the furnace was still not running and reported this to the service tech when he came out, hoping that the initial problem might be identified so as to avoid a recurrence. Nevertheless, the tech wrote on the invoice that the unit's memory was blank and there was no indication of what the problem had been. That misinformation no doubt helped bring about a subsequent repeat of the above scenario when, a month later, the furnace again would not start: for the same reason as the first time, the defective component having been correctly identified (as it turned out) by the series of flashing lights about which I had informed the first tech, and which he apparently chose to ignore. I called again for a repair tech but beofre he arrived, the furnace again came back on after several hours of not working. There was a lot of snow coming down that day, so I called back and said that I was okay with them letting the tech wait until a day when the driving was not so dangerous, since the furnace was running. They thanked me and said that the tech would be there on Monday (three days later). I also had concerns about the actions of the first tech and asked to speak with the service manager. He was unavailable, I was told, but he would call me on Monday. I never heard from him. The tech also never showed up on that Monday, nor did any one call to tell me he wasn't coming. I gave up on this company as they appear to be unreliable. It's a shame because I'd used them in the past and they used to be reliable. They did. however, call back a week later and asked me when I wanted someone to come out and replace that part. I told them I would be using another company.
Description of Work: Was originally called to find out why the furnace had stopped running.

I cannot thank National enough for repairing my air conditioning. I have a Carrier system, that failed about 4 weeks ago during a heatwave. I called another company and they tried to fix it, but after 4 visits, 4 weeks and several replacement parts it still didn't work. Their next suggested fix was to replace the Carrier control system with an inferior system - at this time I contacted Carrier and they suggested that I call National. Best decision ever! National were extremely responsive, polite and professional. They sent someone out on the same day that I called and he diagnosed and repaired the air conditioning within 2 hours. I'm sure that it would it would've been faster, but the other company had disconnected some wires and he needed to trace and reconnect them. Awesome service! I will definitely use National again to service and repair my air conditioning.

I had no air conditioning and called for service. I needed a new outside unit but ended up replacing the entire system and my old electric water heater. It went very well and they did what they said they would in spite of the hot weather. The cost was alot for me but I had another price from a different company and it was comparable. I was most pleased they showed up when they said they would. They were clean and neat. Im happy and enjoying how much better the system works. Its night and day.

Northern Refrigeration was extremely responsive and professional from my initial contact for an estimate through the final installation. The crew of workers that were at my home for four days were very professional and polite. They ensured all debris from the installation was removed upon completion. The work was completed within the timeframe communicated to me when I signed the initial contract. I would highly recommend Northern Refrigeration for your HVAC needs.
Description of Work: Northern Refrigeration installed Central Air Conditioning in my two story home. The home required two central AC units and air handlers as well as the installation of all duct work.

Description of Work: I called National on a tuesday afternoon because I had no heat. Doreen was able to get Jarred out within 3 hours. He looked everything over and told me my system could be bandaged together but recomended I replace it. He got my heat running for the night and told me the office would be in touch with a quote for a new system. The next day Jack called me and discussed what my opinions were on efficiency and wether my hot water was adequate. He listened to my answers and told me he would email me a proposal that afternoon. When the proposal arrived I was very happy to read it and actually understand it!!! I am not a technical person but he provided model numbers as well as links to the web pages of the manufacturers so I could read about the furnaces and tankless water heater he reccomended. I finally decided to replace my air conditioner as well due to the new freon gases. Once I signed the contract Doreen kept me informed and approx 1 week later 3 nice young men arrived at 8 am and explained what they were going to do and then proceeded to put down drop clothes and put on shoes covers. They worked all day and then cleaned up at the end of the day. They informed me the new heat was running but they needed to come back again tomorrow to finsh the job. They arrived again at 8 and put drop clothes down and went to work. I have to say my new heat works great. It is so much quieter and comfortable than my old rusty heater.. I dont know how the ac is yet but it is supposed to be twice as effiicnet as my old clunker. I wish I didnt have to spend the money but I feel I got more than my moneys worth from National. The whole experience was very professional and everything was done just like they said when they said. I plan on replacing my water heater with a tankless next year. Im glad I found this company.

They said the air conditioner was fixe, but I noticed the fuse was blown out. I then called them to check the same and was advised it must be an electrical default. I hired an electrician to check the same who advised there was problem with the external compressor. I called them back advising the same and they said they will not come out as the air conditioner was in a working condition the last time they came. I do not recommend their services and will not use the same in future.

They did excellent work. I have no complaints with them. They gave me a fair price for the system I purchased. They took the time to explain everything to me. They were supposed to follow up with me with a kit about my unit, I am still waiting for this. The service tech was a great guy and handled the job well.

The price that was paid was about $10,000. Everything was fine and it took a little longer that I expected for the parts to come in, but it was not them. The front office was very nice and efficient, and a few issues we had the next couple of days with getting the temperature or thermostat right. They came right in and fixed it, so there were no problems.

Brian, the tech, was excellent, attentive, neat (cleaned up everything), available to answer questions, and on time. Work was finished in the estimated amount of time for exactly the estimated amount. He had to return to install the thermostat as he had been given the wrong one. He returned on the date and time we asked him to. No complaints.

National's work is first rate. Front office was very professional and accomodating. Technicians have been professional, thorough, competent and courteous. The quality of work done was very high. They were careful to keep the house clean during the job (even wore shoe covers when they came into the house), and cleaned up everything inside and out when finished. Work was done when promised. I think their prices are very fair. Being new to the area, I didn't have an established account with a local HVAC contractor. I called four companies. National was the only one that set up an actual appointment to service the system. The appointment was changed due to emergencies of estabished customers, but they called to explain and reschedule. They welcome new customers and worked to get our problem corrected quickly. Scheduling priority is given to established customers. I am very glad that I am one now. I highly recommend this company.
Description of Work: National fixed many many problems resulting from a different contractor's poor (I'm being kind) installation of original HVAC system. The house was built 2 1/2 years ago.
