Dukes Heating And Air Conditioning

Dukes was referred to me by a duct cleaning company as our furnace was installed by our old Home Guard Warranty incorrectly and illegally. Home Guard sucks by the way! LOL But anyway, We also had another company come out and give us an estimate of over $ 10,000 worth of work they said needed to be done and they said we needed a new furnace as well when our furnace is only 4 years old. Duke came out and said he could do the small fixes to get our furnace up to code and also gave us estimates to do some other things (remove a wall heater, correctly install our bathroom fan exhaust through the roof and make our air return on our furnace bigger so the heater wasn’t so loud when it was on). We went with Dukes and they came and did the work today and were very professional and clean. All the work was done correctly and we are pleased. We will use Dukes for any further heating issues we have and refer them to others as well.

Duke helped us twice in two days. This review is for both times.
For the first time — we tried to install a Nest thermostat and for some reason could not get power/​connection from our furnace to the Nest thermostat. We called Duke in the morning and he was able to come out that afternoon. He helped us with our Nest issue, recommended a different WifI thermostat for compatibility reasons, and made some minor tweaks to our furnace. He was extremely nice, helpful, and responsive.
For the second time — after installing the other Wifi thermostat that same day, there was no longer any power to our thermostat. We again called Duke (in the evening) and he was able to fit us in first thing the following morning. Duke came to our house, was able to fix the problem, and was extremely helpful.
I would definitely recommend Duke to anyone with heating and air conditioning issues!

Duke installed AC and new Furnace back in April.
AC worked perfectly during the hot summer. Winter came around and time to turn on the heat. No heat just air. Called Duke on Monday and he came the next day. Turn on the heater and everything fired right up. Root cause possible air pocket in the pipes.
Service from Duke have been excellent from the original installed to this one time service call.
He also checked the air filter while he was here and reminded me to change it. Would recommend!
Definitely a step up in service compared to the big box stores.

Duke, Jesus and Juan were impeccably straight-​forward, honest, communicative, courteous, punctual, clean and professional. They performed an extensive inspection of both my AC and furnace only to suggest service and repairs totaling roughly $ 700.00, while a couple other companies (one small and one quite large) were pushing for a new system installation ranging from $ 10 — 15K.
Duke and his crew earned my trust and business. My «old» system is now running like a champ! When my AC and furnace really need to be replaced, they will get my business.
Thanks, Duke!

I was getting estimates to replace a furnace that was about 20-​ish years old. I had a couple other guys come out, the first telling me the furnace was so old they don’t make parts for it anymore (which he reiterated after «researching it» and calling me back a couple of days later). Duke came first thing in the morning and took one look and said the furnace still looked pretty good and asked if I was sure that I wanted to replace it. He did a few tests and said what he thought the problem was, the gas valve, which should be reasonably cheap to fix. He then gave me a quick estimate for the replacement, thoroughly explained the details of furnaces and why he created the estimate he did and the options he included. Then, when he was done with the estimate he when to his truck and verified he had the part to fix what I needed. He gave me a decent price and was willing to do the repair right then. late the night before I had a similar situation with a different vendor so I didn’t hire him but he was so honest and such a good guy I would be happy to use him if the opportunity presented itself.

I agree with the other 5 star reviews here. What a seamless and painless experience. It’s bad enough when a heater breaks in the winter. Duke (himself) answers the phone, schedules a convenient time and actually shows up on time. He fixed the thermostat within an hour. Plus he had the part in his truck. I’d pay triple to not have to order and wait for a part. Fast, friendly and efficient. Thanks Duke.

After another service company came to our house to fix the air condition an initial quote of around $ 700 (repair) or $ 10.000 replacement, Duke provided a 2^nd opinion. he fixed the issue in 2 hours and for half the initial cost he fixed the system.
He showed up on time with only a day notice. great service.

I have used Duke’s for more then 5 years. I have checked around and Duke is very reasonable and great quality work. I always call on Duke for all my Heating and Air Conditioning needs. Duke will also make weekend visits if he is available.

I’m not sure why the negative reviews? Of course he has to charge a service fee and of course he is going to mark up parts. He is trying to run a BUSINESS. In a BUSINESS you need to make a profit. You certainly can’t do that by performing work for free or supplying free parts.
Duke came to my house today, fixed the problem and replaced my filter. He said if the problem happens again he will need to replace a part but didn’t think it was necessary UNLESS the problem happens again. If it happens again, he will order the part for me and install it free of charge within 30 days of his initial service call.
Duke showed up within an hour of my call, was extremely polite and personable, fixed the problem quickly, and charged me a very fair price.
No problems here, Duke is great!

Not recommended. Go somewhere else.
Our furnace was broken before Thanksgiving and we called around for a heating contractor. Duke’s Heating was recommended by a cleaning duct company. We called Duke’s and the man on the phone said he will be there the next few days without mentioning a charge for a service call. We checked Duke’s heating website and we saw this «CONTACT US TODAY FOR FREE ESTIMATES ON OUR HEATING AND AIR-​CONDITIONING SERVICES.» on every page of their website. Duke’s owner, Milton, came over to our house and he didn’t present a contract for service call for my wife’s signature before taking a look at the furnace. He went directly to the furnace and found a bad valve part. He told my wife the cost for repairs was like $ 425 and my wife text me for my approval. I told her no and we needed to find another company for a second opinion. Milton told my wife that she had to pay $ 95 dollars fee for service call. My wife was puzzled that she didn’t know this before. She didn’t sign anything before Milton looked at the furnace.
I had no choice but gave him an approval to do the repair. He charged us least $ 425 dollars. Almost $ 250 bucks for that little valve part that you can buy the same part on line for $ 130 dollars. That was a huge mark-​up!
We tried to work this out with Milton Duke to settle this issue about $ 95 service call and Milton refused to cooperate with us. We weren’t able to contact a second contractor for a second opinion. We filed a complaint with the California State License Board.
Few weeks later, my wife came to the house and smell strong gas all over the house. My wife went to the furnace and heard a very strong hissing sound. She turned off the gas valve.
We called PG&E and they sent a gas technician to take a look at the furnace and discovered that the valve part, installed by Milton Duke, was faulty.
I emailed Milton that our furnace is broken and we want our money back. Milton came over to pick up the part and gave us a refund check.
I will never use Duke’s Heating again.

$ 125 just to show up… but on a Friday night, when its 90* and you’re A/​C is out, you’ll do what you have to do.
Nice enough when he (Duke) came out. Replaced a capacitor and said it would last the weekend (it didn’t) Set up an appointment for the next Tuesday to install a new fan/​blower. $ 90 service call, $ 220 for the motor. We’ll check your attic as well to make sure things are OK nice I had some insulation clogging things up. OK fine. Seems fair.
Never heard back until Tuesday as scheduled, (they were late). Started to unload their truck to start work and I asked for a quote since I had not received anything in writing to this point. Will say that he did not charge me that Friday when he came out. Would add it to the bill when the job was done. Again, fair enough… So I ask for a quote. The repairman knows nothing and has to call Duke. (Here’s where things get sticky) They must have lots of trouble hearing each other I guess because it took quite along time to get a simple number. $ 620+ dollars.
Ever hear of Bait & Switch??? After I got up off the ground (I fell over) told them to pack up an leave.
Called Alton A/​C. They were very busy since this was the hottest weekend/​week of the year so far, but they managed to get a tech over. Confirmed the motor was in need of replacement and had a motor, but the mounting bracket wouldn’t fit right. They took everything back to the shop, made an appointment for the next evening so I did not have to take more time off work and fixed everything. Pretty cool. (no pun intended) Oh yeah. Their quote, over the phone, $ 320.00. The bill I received. $ 320.00. Imagine that. An honest A/​C company.
I’m sure his version of the story will be a bit different, but much like the capacitor he installed, it won’t hold up to the heat.
PS. It’s one star because you cannot give NO STARS!!!

He is very professional, the work is quality, he has integrity, and I felt like he wanted what was best for me. He and his team are amazing.

I have no problem recommending this place.
He comes across as very trustworthy and the service he provided fits within that impression. He was very prompt on both visits. He is easy to understand, and will take the time to explain things.
As with any A/​C diagnosis, the potential exists for an expensive repair. This didn’t «disappoint» in that regard. After a simple freon charge didn’t do the trick, a couple of trips up into the attic determined that an expansion valve was malfunctioning. His estimate came in at $ 830. (ouch) …But in the end, it was simpler than he anticipated. The bill ended up being $ 654 for two visits, a new expansion valve, and a few hours of work by two men.

I had dukes repair some heating ducts and install new ducts to some bathrooms. This required breaking through some stucco to vent the new ducts. This work was done well and seems to be high quality.
I’m perfectly happy with their work. I’m rating 4 stars because I don’t know how price competitive their quote was. I called 4 companies, and Duke’s was the only company to bother providing a quote.
I would use them again.
