Clinking noise 4am....furnace not turning on. I go down to look..hear the noise....and know that there is a problem and these kinds of problems cost lot of money. Jumped on YELP...starting checking out some of the local folks ( since I live in Half Moon Bay. Liked what I read about Dennis. Called him...he was out at my place in an hour. Had the parts...fixed it...explained it all...an hour later all fixed. There is something to be said about customer service, honesty, and efficiency that we all look for as consumers. I am not related to or have any part in Dennis's business. As a Yelper, I want to make sure that others know the difference between a real service oriented business and those who are out only for themselves and care little about the consumer. Well done, Dennis. You have my 5 stars! read more

Dennis is responsive, professional and a joy to work with. Came out right away to our house in HMB to check on my furnace in the attic that stopped working. Investigated throughly and determined it is due to electrical issues and not the furnace itself and coordinated and brought along Dave from WireWorks the next day, whereby the two of them went through all possible scenarios and finally tracked down the hidden short that cause the outage to the furnace. Cannot thank them enough for being honest, good people that I'd call again in a heartbeat! Thank you Yelpers, for letting me find great people to work with! read more

Found AMS on Yelp. I'd bought my home 10 years ago and always had 2 rooms that stayed very cold - heat just never seemed to get into those rooms. Had my furnace and vents checked a couple of times but no solution. Just recently, I decided to get to the bottom of this problem...I was determined to get heat into these rooms. I got an estimate from company referred from a friend. The guy came out and told me that the ducting going to those rooms, plus a poor connection with the ducting leading to the furnance in the garage were my problems. Solutioin - replace ducting in these areas, plus... blah , blah for a cost of several $1,000 dollars - yikes - "do I really want heat in those rooms", was my new question. I decided to get a second estimate from someone in my home town of Pacifica - thank goodness. I called AMS and Dennis came out the same day - and within 10 minutes (NO KIDDING) I had heat flowing into those rooms from him adjusting the fan speed inside the furnance....wow!!!! In these tough times, it can be hard to find folks with integrity, fairness, and extensive knowledge of their craft - but there's no shortage of these values and qualities at AMS! Thanks again Dennis, you're the best and I really appreciate your help. read more

Dennis was so incredibly knowledgeable, prompt, responsive, and helpful, all with an extremely personable approach. I called him because PG&E had shut off our furnace after detecting a gas leak. Apparently, one of the valves had failed. I had no idea who to call, but after seeing Dennis's good reviews on Yelp, I decided I had little to lose (I was already freezing in Pacifica's fog). Dennis was at our home within an hour from the time I called him. He reassured me that he could fix the leaking valve and thought he might have the part at the shop, but he wasn't sure. Within a couple of hours, he called me back, told me the part was on order, and that he would come Monday morning (this was Friday). Sure enough, he came, he fixed, he charged a very reasonable rate, *and* he had doggie treats for my dog. He is probably the first repairman I've ever seen who didn't look at my dog with fear. If I ever need help with a furnace or *anything* HVAC-related, I am *definitely* calling Dennis! Shop local. :) It works every time. read more

Dennis had come out earlier in the year to inspect our furnace. He could have said "The crevulator needs to be replaced" and charged us $100 and done nothing, but he gave it a clean bill of health and the bill was next to nothing, so when it crapped out this morning, we called him. He told us he'd be out (on a Sunday!) between 5 and 6, but called about 3 to tell us he was on his way. After the inspection, he said the thermostat had died and that, while he could replace it himself for $150, we could do it ourselves for $35. He explained the process, and (even though the unit ended up costing $60) it couldn't have been simpler. (He even offered to talk us through the procedure over the phone if necessary.) So to sum it up, this is a guy that could take advantage of people and overcharge them without their even knowing, but who'll take the extra step of being straightforward and honest and dirt cheap. read more

I needed someone to come out and clean my wall heater. After calling PG&E to turn on pilot light they ended up completely shutting off the heater because they said it was clogged with dust and hair. So I called AMS around 8:30am and they were at my door by 9am. Dennis took apart the heater and cleaned it out. He stated that the heater was in good shape and PG&E should have NEVER turned it off. Fortunately, Dennis ended up only charging me a fraction of the cost to service the heater. I would RECOMMEND AMS to anyone who needs heater service. read more

Furnace broke down on a cold winter's night! Awww sheeeeeit! Couldn't figure out hiw to fix it myself. Called these guys based on their awesome reviews. Dennis came over on a Saturday late afternoon and provided us with the highest level of friendly, professional service! He diagnosed he problem quickly, found a replacement part in his truck, fixed the furnace quickly, and within an hour of his arrival, WE HAD HEAT!!! I can't thank him enough! I highly recommend this company to anyone in need of furnace repairs! Call these guys first! You'll be really glad you did! read more

Dennis came and fixed our fireplace a year ago. A year later it broke many times and every time I called Dennis, he's always pleasant, responsive, honest and stands by his work. He had to replace the valve at no charge. In addition to his honesty and hard work, he goes out of his way to help you in area that is not related to his field. It just happen that I mentioned to him about a noise coming from the wall. He took the time to troubleshoot the problem and he was able to identify the source which was the toilet. He refuses compensation and he was happy to help us. We are very grateful and thankful for Dennis to resolve this old mystery!! read more

Per AJ.J's review; that probably explains things. Called AMS twice and left phone messages but never received a courtesey return call and I live in Daly City. Looking for another sheet contractor now. read more

They have been to our house two years in a row now and have provided excellent service. They are willing to crawl into tight spaces, where most shutter at the thought as the heater is located under the house in a tiny crawl space. At Christmas time, Dennis the owner came out and fixed our heater when we accidentally turned it off (yes that happened) and did not charge us any house call. That is top notch in our book. We have recommended him to friends and will continue to use AMS as well as recommend them to anyone who is in need of their services. read more

Dennis and his son at AMS Coast Sheet Metal go above and beyond. Whether I stop by the shop or call, I am always greeted warmly and given excellent service. Dennis takes great pride in his family business and ensures the best quality care. I feel confident my wall heater will keep running with AMS. read more

Dennis took my call in person on the first try (no voice mail phone-tag), showed up the next morning (on a Saturday!), and explained his work to me the whole time. Forty minutes later our furnace is working again, and his fee was extremely reasonable too. Doesn't get any better than that for customer service. Highly recommended!!! read more

Simply put: Dennis was awesome! - Answered my call, showed up same day. - He explained everything that was going on and gave honest advice. - Replaced the motor on our ancient furnace, checked for carbon monoxide, and inspected vents/duct work. Nice man, great service, and has a sweet dog. Thank you. Call AMS...it's a no brainer*. *Edit for spelling. read more

I am a photographer making Tintypes. As I live in Pacifica I thought I would support my local business by buying cut sheets from AMS. Dennis and his son run a true family business, and it is very no-nonsense. Simple honest service with a smile. read more

All I have to say is if you have problems with heating or airconditioning in your home, DONT WASTE YOUR TIME calling other companies or shops quoting you ridiculous price quotes for repairs and replacements. Call AMS and speak to Dennis. This gentleman together with his son will do an excellent job! He is very courteous, honest and professional. My wife finds him very respectful and kind. It's always nice to find a company like AMS to do an excellent and quality job without fears of getting ripped off. Dennis and his shop AMS deserve more than 5 stars! read more

So we finally replaced our furnace!!!! Dennis came out on a weekend day to check our furnace for it had stopped working....looked like our pilot light was out. He told us that if we wanted to replace our furnace he would credit this call onto the bill...we scheduled the following Friday and he and his son came out. Not only was the furnace and work priced fairly, they were courteous, on time, safe, nice, and thorough. We have an efficient and quiet furnace now, and what a great feeling to know that there are People like Dennis and his son around that you can trust to help you with your heating needs. So happy and pleased with the work!!! Nothing like staying local too.... read more

AMS fixed my heater. Excellent service. Friendly, very prompt and helpful. I highly recommend AMS.

I have never paid AMS a dime; tried to, but helpful Dennis refused. For that matter, I've never written a YELP review before either; but this outfit has inspired me to do so. I called them with a question about my furnace and Dennis of AMS asked where I lived. When I told him, he said it was on his way to an evening out and could swing by and show me how to 'fix it myself'. He showed me just what to do - nothing too complicated. When I finally got around to it I forgot one key step and shorted out my system. I called him again (on a Sunday) expecting to finally pay for some professional assistance. Instead he coached me both on the missing step and how to fix the problem I'd created - all over the phone and at no charge. Great neighborly customer service - even when you're not a paying customer!!! read more

Dennis is awesome!!!! Gave ams a call and Dennis was here in 10 mins... Our heater works again!!!!! Great super fast service!!!!

My furnace died and the AMS guy had it fixed within a few hours. Couldn't ask for better service. This was actually a year ago and I'm finally getting around to posting a review. read more

Dennis is GREAT! We hired him to fix our heater and found him to be very professional, on time, pleasant and fast! He even came over the Friday after Thanksgiving. read more

I gave 5 stars to this place. I searched through Yelp and read all the nice review about Dennis, the owner of AMS. The Yelp AMS positive reviews are accurate! I called Dennis and told him that the house is cold and the pilot of the furnace is off when I turned on the heater knob and the filter has not been replaced maybe for 5 years or more. He scheduled that he is coming the following day. He changed the furnace board and cleaned the filter. He completed the work and tested before he left. He even showed me how to replace the filter next time and told me to replace every three months. The price (labor) is the same as other places but one area that AMS excel is the service and knowledge that Dennis provided to his customer. This father and son business is a busy business working 7 days a week until midnight according to Dennis. I highly recommend this place to anyone that relies on Yelp. read more

I highly recommend this business if you like to deal with slow or unresponsive individuals. I called them four months ago and did not receive a returned call until a month after I left a voice mail, someone named Todd finally called back. I spoke to him about getting two wind directional chimney caps, emailed him some pictures and dimensions but never to hear from him or the business ever since. Good thing I did not put down a deposit as I would not want to do business with an operation such as this. read more

Dennis is absolutely great to work with - trustworthy, super responsive and knowledgeable. I have had him out twice to fix problems with my heating unit, and both times he came over right away, identified and fixed the problem within 15-20 minutes. I highly recommend Dennis and AMS Coast Sheet Metal, Heating and Air. read more

I called AMS Coast Sheet Metal at 10:30 am on a working day. I spoke with Dennis (I presume the owner) and explained my heater was not producing heat, but the fan was running. Dennis said he could come that day to check out. He showed up at my Half Moon Bay residence a 3:30. He had the part in his truck, and 20 minutes later I had heat. Awesome service! read more

I agree 100% with the rest of the Yelpers' glowing reviews on AMS Coast Sheet Metal Heating and Air. Dennis could not come in Friday to fix my heater, he was too busy . He told me to call Monday. I decided to wait for him due to the great reviews he has on Yelp ( plus my heater had not worked for more than a year, so what's two more cold days ?). I called back at 7:55 AM Monday, by 830 he was at my place and by 11 am he had replaced the broken motor in my furnace. He had to go to SSF to get the new motor. He charged me for the parts and only 1 hour of labor. He didn't charge me with the travel time to and from SSF to pick up the parts. I tried to give him a big tip but he adamantly refused. Dennis is a GEM. He is honest, he obvious knows his trade and takes pride in it. If you need any help with your furnace and heater look no further , call AMS . read more

I just had the most beautiful experience with Dennis. Approaching 50 years of age I can recall the way "it used to be." Dennis has all the character you normally can only hope for, but with Dennis you get a seasoned professional and a business owner that puts his reputation, before his profits. He is honest, competent, and on top of that brings a fresh sense of humor. He is a delightful man and a pleasure to work with. I recall saying to my wife, "Dennis is one of the very few I don't mind writing a check to." He is an individual you feel good about paying. I can't think of another professional I'd rush quicker to recommend, and that includes my MD. Vince Ryan read more

Our experience with Dennis, the owner of AMS Coast Sheet Metal in Pacifica was refreshing. He is honest, hard working, and friendly and we recommend him and his company without hesitance. We had been told in May 2011 by another company that our heater, which was limping, wasn't worth fixing and should be replaced. The heater stopped working two weeks later. Dreading the cost we decided to wait until October to replace. After the first October storm we called three places for estimates; Dennis came first and we are thankful he did. He came on the Friday of Columbus Day weekend - we were scheduled to meet at 4:00 pm. Dennis called before the meet to say he was running late from a job in San Francisco and would be here shortly. I appreciated that because too many would have blown the meeting off and not called. When he arrived and we made our way to the heater, his said to me when he laid eyes on the heater - from a distance mind you - "Oh Joel we do not need to replace this heater. It's too new ['85]. We can fix this." He opened it up, started it up, listened and poked, and then pointed to the fan on the motor and said, "Here's your problem." The motor was not making the full revolution because the wheel inside the housing was busted. After removing the motor, Dennis removed the wheel to see if motor could be salvaged but too much damage had been done by the broken metal. He told me he would drive to his shop, get a replacement motor, and be back directly. I said he could wait until next week since it was a holiday weekend but he insisted. Dennis returned as promised and replaced the motor. We were prepared to spend thousands of dollars to replace a heater that needed a $187 motor - something that took Dennis two minutes to figure out. He could have exploited the fact that I was ready to spend the money but he didn't, which is why I am writing my very first Yelp review. Thank you Dennis for reminding me what honest workmanship is. read more

Punctual, more than fair in his pricing and honest -- really it doesn't get any better than this! We had a problem with our wall heater and Dennis did an outstanding job in making sure we were up and running as soon as possible. He also checked and double checked his work and then cleaned up after himself. We are so happy -- it just doesn't get any better than this! read more

After getting an appointment 1 week later to repair my furnace - 51 degrees in the house - from other coastside outfits I called AMS. Dennis came out the next day and had the furnace running in 30 minutes. Couldn't have had a better experience. read more

Well, the positive reviews are all true--just gave AMS a call and within 2 hours he was under the house solving the mystery of the broken furnace. He spent over two hours figuring it out, going back to the shop for parts and making sure everything truly was fixed--even came in the house to make sure there was no detectable carbon monoxide because my unit is so old. The furnace is now humming away and I dodged having to replace an entire unit. Awesome service--super prompt and professional. No upselling or price gouging--this guy is the real deal-- honest and competent-- you can't do better. He knows his stuff, looks out for the interests (and budget) of the customer and is very kind. I highly recommend-he now has a customer for life. read more

Our furnace stopped working near the end of 2014 and we called AMS. Dennis came to our house and immediately went to work to diagnose the problem. Unfortunately the heater was working fine but he went through several diagnostic tests until the heater again died and he was able to determine the problem. He left to find a new gas valve and called when he had the price for the valve as well as giving us an accurate quote for the entire job. After the valve was installed the heater was not running smoothly and he diligently worked through several heating cycles to adjust the valve settings to ensure that the furnace remained working after he left. We asked if we should get a new heater, he told us to save our money and that even though our heater was older it was working well. When we asked him about a service plan again he told us that with the type of furnace that we had, very little service was required and that we would be wasting our money. How nice is it when a contractor tells you not to waste your money? Dennis was knowledgeable, industrious and honest. I highly recommend him and am grateful to have found a trustworthy HVAC contractor. read more

@ Shaun G re:msg rcvd.. If businesses only service one town or particular location, they should post that info. If a potential customer waits on hold and the business says they now only do work in Pacifica, then advertise that info so ppl don't waste their time. read more

It doesn't get better than this! Dennis is an amazing man, he runs a business where the needs of the customer are first. He calls promptly and regularly to let you know he had either received your call or is following up with info he promised or to arrive at your house. His son, Todd is also customer focused and low key cool. We are so fortunate to have met them when others flaked or buckled under construction timeline constraints. We will continue to call on Dennis and Todd and will share with our friends to reach out to them when they have heating or sheet metal needs. Thank you read more

I was not getting enough heat to my bedroom- was sure I needed a new heating system. Dennis from AMS Coast Sheet Metal came out and very quickly assessed what was wrong. He was thorough in checking everything and was not out to make a buck, like so many companies are. His estimate to replace our system, should we decide to replace it, was lower than I expected. I will definitely recommend them to friends and should we decide to replace the system, these are the guys who are going to get the job! So refreshing to find a professional company with good old fashioned home town values. read more

If you need help with your furnace, look no further. I had been putting off making the call to have my furnace looked at for a long time. Finally the weather got cold enough and the furnace so dysfunctional that I had to find someone. I selected AMS on the basis of yelp reviews, and have to say it worked out better than I could have ever thought. Dennis is a knowledgeable craftsman, highly ethical, and gets the job done. It took a bit of tweaking but he spent the time and finally coaxed my furnace into submission. The fact that he is an animal lover is a bonus! read more

This gentleman went out of his way to help me with a special order. Can't say enough good things about him and his business. Its another business we should be proud to have here in town. read more

I didn't know who to call, but tried AMS because they have an A+ BBB rating. Anyway, Dennis, the owner, came out and lit my furnace. He also showed me how to do it, and gave me some information about my main furnace, which was installed recently (by another company). He told me that two parts of the job were not done up to code, and he told me how to approach the company to get them do it right without charging me. Neither of my heaters were installed by Dennis' company, but he still provided service and advice, without asking for a dime! He told me, "service is just a normal part of doing business." So, I found my furnace company and will never use anybody else. He knows his stuff, I trust him, and he deserves an A+ for service! read more

Was told I needed a new heater elsewhere, Dennis came same day, during winter season when others told me 2+ week lead time, fixed in 30 minutes, told me heater was still good for a few years and a few maintenance items I could look out for myself to extend the life. Quickest and best service I've had. read more

Professional, courteous, and impressive customer service from Dennis! Our downstairs furnace stopped working awhile ago, but we procrastinated in having it checked out. As the wintry chilly days on the coast are becoming intolerable without wearing layers of clothing and beanies, and we're hosting a holiday party next week, we finally decided to call Dennis based on his great yelp reviews. He was able to drop by within minutes of my call yesterday, quickly diagnose the issue, and return later with the necessary replacement parts. He even uncovered and repaired a very dangerous and unsafe "quick-fix" that a prior heating company had done to our system a couple of years ago. Dennis is definitely a master in his industry, and the icing on the cake is that he's a local business. Thank you, Dennis, for warming our home in more ways than one...you will definitely be our "go-to" guy for any heating issues from here forward! read more
