My AC stopped working during the hottest Bay Area heatwave. I called m&s HVAC to come take a look at it. They arrived within less than 30 mins and fixed the issue and got my ac working again within the same day. Amazing customer service and very efficient work. The price was so reasonable and I was so happy with their work and service. - Jill read more

He was great. Easy to set up an appointment. Showed up right on time. He knew exactly what to do and fixed my heater right then. It works perfect now. Not only was his price better than my first quote it fixed it on the spot. The first quote said I would have to wait 4-5 days for him to get the part. He also quoted a lot more. I highly recommend him. read more

I called M&S for a tune up on my AC unit...largely because of his great reviews. Roger returned my call promptly yesterday...asked if he can call me in the morning after he knew his schedule for the day...and sure enough...called me as promised...said he'd be by in less than an hour...and he did! My unit's filter was beyond filthy. Roger took it out to the street and used a broom to first get the big stuff off and then washed it. When he took it to the street, he noticed the dust/dirt was being blown by the wind toward my house and moved further down the street as to not have the dust blown toward the house. Might not sound like much...but it was that kind of detail that showed me the guy had genuine concern/care toward his customer. My unit needed 2 lbs. of freon...he fixed a vent so it worked correctly and my unit is working top notch in this high heat. He called to my attention the furnace was getting old and wearing down...showed me where the residue indicators were...and basically informed me to ride it as long as it works...and that he'd be happy to provide a quote when the time came. Bottom line...great guy, worked efficiently, priced right...I'd recommend. read more

Roger is great! He very personable and friendly.. He's professional, punctual and He knows and takes his work very seriously..we've used him many times for many different things and he's always come thru for us and his prices are very reasonable. I would def recommend him to any of my friends or family.. read more

Roger fixed A/C in less than 45 minutes. Trouble was identified in less than 20 minutes or so. I'm grateful to have A/C back especially when the previous repair person gave up. Also note this was a same day service call. -timely -knowledgeable -efficient Highly recommended read more

I had a furnace that would not turn off and was only pumping out cold air. Roger came out in a timely manner and told me a piece needed to be replaced in the furnace as well as the thermostat. He offered to do the work for a reasonable price. The problem persisted for a couple of days because the new part was defective. Roger was able to come back out promptly and correct the problem. Roger was very professional and was able to the work quickly. Very highly recommended. read more

I called Roger to give me an estimate on my furnace which I was told needed to be repaired or replaced. Roger came out and spent almost 2 hours diagnosing the furnace. He then came back 2 days later to try to replace the circuit board, but it didn't help. He ordered a new furnace for me and all is working well. He spent a lot of time to make sure everything was right and was much lower in his pricing than other companies that were selling me more than I needed. He and his crew wore a mask the whole time in my house. I would highly recommend M&S for any HVAC concerns. read more

Hands down the best customer service I have ever received! After placing a last min call on a Thursday afternoon,I had my heater fixed that evening. Rodger and Pabel showed up and identified the problem within minutes. Next thing I know my heater is fixed and working better than before. Even the next day I received a complimentary phone call from them confirming my unit was still running well with no changes. I would not hesitate to call them for any of your ac/heater needs. read more

Very thankful our property management company in San Francisco found these guys to update our old-school heating system which died as winter was kicking in! They came by and identified the problem right away, which another company was unable to do. They did their work extremely efficiently, installed a new system and ensured all tenants in the building got up to speed on how to use it. They were also incredibly polite and managed to entertain my 1-year-old son, who was very curious about what Roger & Jeff were up to. Thanks guys, much appreciated! read more

We've been using M&S HVAC for years -- when the original name was Air Master -- then it became S.A. Heating & Air Conditioning. Now, the business has taken on a partner with the original owner, and it is called M&S HVAC!. We have used other heating and air conditioning companies in the past, and we have never been satisfied for one reason or another -- either they were late, overbooked, or cancelled appointments; OR they gave us outrageous estimates, OR other various reasons. However, we have ALWAYS been satisfied with not only the professionalism of this company, but also the customer service, the expertise of the person who came out on the job, and the price that was quoted and charged for a job. We've made up our own "Diamond Directory", and we keep this company on the front page of the section on heating and air conditioning units (and their repair). We don't ever want to make the mistake of calling some other company by mistake. We want to make special mention of Paul -- the employee who recently repaired the thermostats and wiring on our furnace and air conditioning units during one of the coldest spells Marin County had around the holidays. Paul was not only dependable when he said he would be at our house at a certain time, but he knew what he was doing. He had to make several trips to our home because of the problems involved in our system, but he was always on time, always polite and courteous, very professiona, and he managed to give us the best possible price for the labor and parts involved in the service calls. We would highly recommend this company. Even though we live in Marin County, and this company is in Contra Costa County, they came over to our house almost immediately after we telephoned them for service. There is no way you would be dissatisfied with this company. Ask for Paul -- if you can get him. He is one of their valued employees! Kudos to Paul and M&S HVAC!

Best service! Roger and Mike serviced my apartment several times when the heat was not working. They were readily available to help and were so nice. They fixed my heat instantly and even came back several times to ensure that it was working properly. I give them 5 stars for their service. I highly recommend them. read more

Mike blew me away with his timeliness and stellar customer service. After I reported a broken gas heater to the property management company, he responded by phone and made his way over within one hour. He made a quick and effective assessment, promptly requested permission from the property management company to fix the issue, and within no time my heater was up and running. I will definitely look to this company for any future HVACR issues. read more

After calling many companies, M&S HVAC/R Contractors was recommended by another company. Roger was able to come over on the same day and fixed my 50-year-old heater in 2 hours. He was incredibly polite and explained exactly what to expect as well as the expenses. I would highly recommend Roger for his outstanding customer service as well as attention to detail. Thank you Roger for warming my home!! read more

Roger has come to my house twice now in the last month - both times after hours - to resolve my air conditioning condenser issues. He is very professional, courteous and took the time to answer all my questions. I highly recommend him! :-) read more

Amazingly responsive and great service! Our problem was a wine cellar cooling system that had stopped working entirely. Turned out that the compressor (about a decade old) had failed. After some time getting referrals and calls not answered, I got Roger's number to call. That was a Monday afternoon and on Weds. afternoon, all is repaired. I see many positive reviews for home heating and cooling systems. If you have a wine cellar and need help with the system, I would highly recommend giving Roger a call. Also, do not hesitate to call if you are on the Peninsula, though the location listed is East Bay. Roger was at a job on the Peninsula already so able to make his way to us quickly. read more

Roger and Jeff showed up to my place and did an excellent job. They made sure to get everything working with my old heating system and a new smart thermostat and also let me know that I can call them anytime if I have any troubles. They are polite and courteous and clean up after themselves. I would recommend them in a jiffy! read more

Roger was exceptional and I would recommend M&S HVAC/R Contractors any day. I live in an older home with a heater that hasn't been used in years. Roger came and did a thorough assessment - he was incredibly kind and professional. He explained everything that was needed, provided me an invoice and was back the next day on time to complete the repairs in a few hours. So far it's been working like a dream and my only regret is I didn't contact this company sooner! read more

My home warranty company sent out Paul and Julio from M&S to repair our AC which had stopped cooling. They diagnosed the problem apparently as a bad capacitor and contactor plate. The estimate was for 377 which as I researched it was a bit on the high end as it could have been done for about 250. My warranty company covered it, so I wasn't so concerned. Paul came originally for the diagnosis and then returned on a Sunday morning to replace the parts. He was very professional and was on-time which was appreciated. read more

Roger did a great job at my building in SF. We have one furnace in the attic and you can heat each floor separately. The Heat is even and quite. In another unit, it was pretty tricky to fit the heating system inside the unit in an unobtrusive way. Roger came up with a nice design and it looks and functions very well. Overall, very reliable job with great quality! read more

Michael and Roger were hired by our property management company. They were able to schedule an appointment within a couple of hours after our phone call, arrived on time, and in no time our house heating was fixed. They were very professional, good with my "want to know everything" kids, and pleasant to work with. Both thumbs up! read more

We have been looking for a reliable HVAC contractor for a long time and finally found the best company which is M&S HVAC/R Contractors, Inc. We love this company because of their professional approaches to save the replacement costs of old facilities by creative maintenance to keep running the facilities. Also, their quick response to an urgent issue is always much appreciated. We feel so happy and secured to be supported by this company. read more

A little strange. Pickup truck has no logos, name, etc., tools are covered with a plastic bag in a bag in the back of the pickup, no cover, cab/bed inside is a mess! Picked them out of YP, advert said $35 for service call. Called them on 12/24/2012. They said they would be at my house between 3 and 5pm. They called about 2:30pm, arrived at 3:05pm, and reset a switch on the furnace - max of 5 minutes to fix, and 15 minutes here, filling out paperwork. Did not state what repair involved. I asked what the service charge is and tech said 'normally is $35, but today is $150, because today is a holiday!' All businesses I called were working as regular day, but were booked until after Christmas. I didn't tell the person that on the phone when I called. Got ripped, even though was only here for short time, and did nothing but reset a switch. Will never use them again. No senior discount, wouldn't adjust amount for short time. Could have kept a customer, and a recommendation, but decided to make the haul, and run. Won't ever use them or recommend them, ever. Not a first class outfit, IMHO!! read more
