I was having trouble with my furnace (on the coldest weekend since forever naturally). Mike showed up in about an hour, did a thorough check of the system, set up a work around until a part was available then came back in the evening the day he got the part and installed it.
The furnace is not only repaired but works better than it ever has while I've lived here. They are definitely where I'm going from now on. Thanks guys!

We had a great experience with Duffey's today. Our AC suddenly stopped working this morning and within a short time our house was getting pretty uncomfortable. I called and left a voicemail and received a call back in a short time and was able to make an appointment for the same day, within a couple of hours . The technician that showed up was very professional, was wearing a protective face respirator and kept his distance while in our home. He was able to quickly diagnose and fix our issue and the cost was reasonable. I highly recommend!

My ac has not worked in 8 years. I have had several repair companies out with not much luck except the option to buy a new unit.
Duffey's came out early, found the problem in 5 minutes, had parts with them, and for the first time since moving into this house, was able to get the temp in my house to 74 degrees on a 100 degree day. I will be using them for any hoax need and strongly recommend them.

I was very happy with Duffey's. After contacting 3 other HVAC companies about a humidifier, Shawn was the only one who took the time to walk me through several options. And, on top of that, I was hoping to get the job done super quick, because we had relatives visiting who were really sensitive to the dry air. Shawn got me in--which I really appreciated! Mike installed the humidifier and was polite and efficient. I'd definitely recommend them!

My furnace has been working fine (that I can tell) but I recently installed a Nest thermostat and it sent me a message that my furnace might not be working properly and I should have it checked. Mike came out ran a full diagnostic on my system. He clearly and thoroughly explained what was going on with my system and provided a number of recommendations on how to improve my system's performance in relation to the message I was getting. He didn't try to sell me a new furnace and explained to me the diagnostics tests he ran and the test results. Mike is clearly very knowledgeable about my

I had received a furnace service from another company and they claimed that my CO levels were too high so I would need to buy a new furnace. I was suspicious, so I called Duffey's. They had a technician out within 3 hours and he confirmed that we didn't have a CO issue. The technician was courteous and was good at explaining all the meter readings to me. Duffey's has won my business for the future.

Duffey's does an amazing job! Quick service, friendly, and professional. Shawn and Mike have taken care of us on 3 occasions and they have always been fair and reasonable. They even helped me make a temporary fix over the phone until they could arrive and fix the problem. Fantastic customer service and I would recommend them 100%!! Thanks Shawn and Mike!!

I had to call Duffey's after I had another company come out to service my furnace and tell me that I needed a new furnace. They were able to come out the same day and ran some diagnostics on my machine and explained everything they were checking and what they were doing on the furnace. Turns out the furnace was completely safe and they saved me from buying a furnace that I didn't need. It was the best service experience that I have had with an HVAC company and I highly recommend them if you want honest, reliable and quick service. I am extremely thankful and impressed by their customer

Our a/c unit broke on Saturday night..we made a few phone calls Sunday and left voicemails. Duffey's called my husband first thing this morning (Monday) and had Tim out here by 11:30am. He was friendly and was quick to diagnose the problem (some sort of fuse melting if I understand correctly). He left to get a part and had our unit up and running within 2 hours from arriving. I always get nervous when something breaks that I'm not knowledgable about but I'm glad I found Duffey's on Yelp. Fast, fair-priced and trustworthy.

Tim came to my house after hours, fixed the problem with our AC and diognosed the problem immediatley! Didnt take much time at all fixing the coils and I could tell he is very experienced! He was was super knowledgable and explained the problem and how to fix it in the future, even offered to come back on a free call if there was an issue. I will definitley recommend him to all my neighbors, family, and friends. Very affordable and efficient. Thanks Duffeys for a great technician!

Same day service, excellent service! By the time Shawn arrived, he turned the AC on, and it remarkably came back to life. He explained that the motor may have overheated and may need to be replaced soon, but it's working for now, so we didn't replace anything this time. He didn't charge me anything, since he didn't actually repair/replace anything which is awesome! And, he took a pic of my AC serial number so that he can easily order me a new motor when I do need one! He also spent some time educating me on how the AC works, it's limitations, and how to get the most

My AC decided to stop working the other day when it was 95+ degrees outside. The result: my home became a sweltering hellhole within about 20 minutes. After calling around and getting told I couldn't have anyone come out until at least July 1, I called Duffey's. Shawn told me he was very busy but that he would get to my house that same day. And even though he was delayed due to a problem with his truck, he still showed up and promptly replaced the capacitor. I felt the price was extremely fair and I really appreciate Shawn's willingness to squeeze me in on a day when many other

I knew the furnace in my new (for me) house was old and in need of repair and I brought in a firm which sends out a letter with huge discounts to inspect it (It turned out that I didn't qualify for any huge discounts) and then I had one of the big box stores give me an estimate to replace it. The estimate was way more than I had expected. Finally I called Duffey's for a second estimate because of their good reviews on Yelp.
I liked Shawn right away, and asked him to prepare an estimate which he said he would send later in the day. Even before the estimate arrived I had decided to give

Came home at 4 p.m. to find the A/C not working. I assumed I would have to suffer until the next day but Duffey's was able to come the same day! Woot! So, we're off to a good start with Duffey's.
Shawn was a very friendly guy, prompt - arrived at the time he said he would despite coming from another job. Within the hour he had the problem diagnosed, had parts on his truck and it was fixed....ahhh, cool house again.
Service call, parts and labor were all reasonable - didn't seem too high or too low. He also gave me some tips on things I can do to keep the A/C running

If you need your HVAC system serviced or repaired don't look any further than Duffey's. Shawn came and tuned up our AC and it is running like a champ. Prior to Shawn's visit the unit was running a lot and not cooling the house effectively. Not only is our house cooler (the AC can actually hold the desired temperature now) but it doesn't run nearly as much. I only wish we would have know abut Shawn earlier. He was extremely professional and courteous and answered all of our questions. He made his repairs quickly and for a very reasonable price. I can't recommend Duffey

When you find your AC doesn't work in the middle of a 100-degree week, you need to find someone who can help you out fast! Luckily my husband got ahold of Shawn, who was easy to reach and was available to help us out that day. Shawn gave us an initial quote up front to come out and see what was going on with our AC, which was comparable to quotes we got from others. Shawn arrived on time and was very friendly. I know this is probably silly to non-dog owners, but Shawn was so kind and patient with our little pup who is pretty anxious about strangers coming to our house (he even took some time
