First, he said he needed to make sure we didn't have a leak. Well...we had a slab leak. He referred us to a fantastic plumber (Eddy Ks Plumbing and Heating) that fixes leaks under slabs and he did a phenomenal job. We still wanted to replace the water heater so Joe was patient while all the excavation, repair, and restoration work was done. Joe did a great job replacing our water heater and even built a new stand/table for it. We were billed what we were quoted and he showed up on time and was very professional. We will definitely call him for any future heating, cooling or plumbing needs.

Brian picked up right away when I called, and he worked to find time to fit us into his busy schedule today.

Brian was very professional, and it was obvious that his focus is delivering quality service at an economical price point. He takes pride in his work and reputation. I will definitely be recommending Brian to any friends and neighbors that ever need HVAC or plumbing.

Michael assured me that he would be back in touch with a quote for the job. I never heard anything. A few weeks later, I used Yelp to try and get quotes for that same job and he contacted me again via Yelp, not realizing that he had already been to my house, already been asked for a quote, and didn't provide one. So I won't be using them for my little project, unfortunately. Unfortunately, I also will not be using them to start up and shut down my air conditioner again. The service was fine and they did it average job so I was happy with that, but the fact that they didn't give me a quote when I asked for one and then tried to give me a second quote after the fact was irritating and didn't demonstrate good customer service. You will pay a decent and fair price in line with other heating/cooling folks in town for air conditioning start up/shut down and heater start up/shut down. I can recommend them for that service. I cannot recommend them as far as getting a quote for any air-conditioning or heating jobs. I'm not sure what was going on with them, but they didn't give me any confidence that they might actually follow through with the job since I couldn't even get a quote from them. It's been months and I've not been contacted again about the potential job. Maybe give them a shot but don't be surprised if you are disappointed.

We installed a new HVAC system two years ago and neglected to do routine maintenance since then…read more(except cleaning the washable air handler filter infrequently). The two technicians showed up on time yesterday (promised 9-10 AM) after sending an "on our way" text). They recommended using the pleated filters instead of the blue fiberglass variety. He had a 20"x25" pleated filter in the truck that was a little long for our space. So, he took a pair of shears, chopped off just enough, and used the cardboard form cleared of material to put a border back on! Voila! Another service was cleaning the fins (?) on the outdoor compressor. After turning off the power outside, he used a hose to flush out the accumulated detritus in the unit. Our system is back to working great again! I had a chance to speak with one of the brother/owners, Paul, this evening, to share my feedback on the service call. Sounds like a very nice guy. I thanked him for their well-trained techs.

Our furnace stopped working. We called Duke City, and they were able to come out same day (on a…read moreThursday). Great. They diagnosed the issue within 30 minutes and were gone within the hour. Excellent. Unfortunately, they had to order the part, which wouldn't be in until Monday. Originally, the technician stated we'd pay expedited shipping on the part but they'd be out first thing Monday morning to get the part installed. I asked the tech before he left what was the price for everything. He verbally estimated $350-$375. He said the part was cheap and the labor would be the expensive part. I wasn't given the price in writing, showing the breakdown of the costs (this was my error, I should know better. They called us Friday evening to let us know they couldn't make it Monday as they were short on technicians. So after being quoted a price WITH expedited shipping, and to the fault of the company, we waited for install- we expected that original price to go down. They came that following Wednesday, and it was fixed within 30 minutes. (This is a total of roughly 2 hours of service, generously.) Total cost $374.06, after they were nice enough to give a 5% military discount. Again, an invoice wasn't provided. However, I paid, and they were on their way. My wife immediately pointed out the math didn't add up, 2 hours of service ($85 x 2 + $55 for a part = $225 plus tax). She called after the tech left to follow up regarding the charges. I received my invoice the next morning around 8:30, as follows: $195.00 for the part (hot surface igniter) $170.00 for labor (2 hours worth) Plus tax I began to do research, as the original quoted price for the part was roughly $55. (Companies in the area won't release parts prices or sell to the public, only contractors, so when I called myself, prices could not be provided. However, I found the price for the part online, ranging $49 to $58, which is not the wholesale price that contractors get.) My friend, who works for a local HVAC company, did a little research for me today. Here were the costs of the parts, as quoted by the 4 parts companies that they called - 1) $17 (the company Duke City got the part from - Johnstone Supply) 2) $13.76 3) $16.57 4) Same price as above, but plus shipping. Duke City charged me $195 for a $14-$17 part through their company. That is flat out robbery. I understand wanting to make a little extra profit. Business has to make money. But, even giving them the benefit of the doubt, and saying they spent $20 on the part, that's almost 10x the price of the actual part! My wife called Duke City and questioned Gloria, regarding the markup. She told my wife, "Well, that's the price that was quoted by the first technician that did the diagnostic. I don't know where the miscommunication happened." Upon further request of resolution (as an "oh well" is not sufficient, she was told one of the business owners would follow up by tomorrow morning). We will never do business with this company again. I will spread the word. Through social media, word of mouth, etc. UDPATE They sent me the invoice that they claim came from the parts company (Johnstone) and they broke it down as $88.60 for the part, and $99.55 for the freight/handling. Remember though, up above my friend clearly got a quote of $17 from the same company, for the same part. So something is up. Also, $99.55 for freight/handling?! They paid for what? Expedited shipping? Even though they knew they couldn't make it out until 3 days following their original promise of installation (Monday)? Give me a break. Not buying any of it. Regardless, if they gave me that price breakdown on the initial day of diagnoses, I would have turned it down. But, they didn't. They just verbally gave me the estimated cost of the whole project. Their verbal breakdown nowhere near matches the black and white invoice. Which, again, was 4 hours of service and a $55 part. At the end of the end of the day, yes- the original price matched. But Duke City changed their breakdown- now, our invoice shows TWO hours of service and FOUR times the original quoted price on the part (when, really the part is only $17, as verified by another local HVAC contractor). Now, my own opinion is that Duke City works with this company to inflate the prices of the parts that they sell. (We were also told by our friend, Johnstone will match a company's original quote to a client in an effort to support small businesses, regardless of what the actual price is.) This leads to return business for the parts company, and increased profits on behalf of Duke City for parts. (No wonder these parts companies won't release the price of the parts to the general public.) No matter the reasoning though, it's clear there is really something morally questionable about this company. Do business with them at the risk of your wallet. Imagine how many people they did this to before us?
