I was super impressed by Steve today. He came out last minute and was able to resolve the issue quickly. Would not hesitate to use Steve's services again. read more

Called Steve in the morning and he was able to visit our house and fix our furnace issue within 30 Minutes by mid afternoon. A friendly gentleman who we will be working with in the future when needed! Thank you Steve. read more

Our AC broke Friday at 5:30 pm. and we thought we would not be able to get it fixed until Monday at the earliest. Our son recommended we call Steve, so we did. He answered our call at 6:00 pm and said he would come out on Saturday to fix our unit. He showed up early Saturday morning and thoroughly inspected the unit. The issue was quickly diagnosed and explained in clear terms, without technical jargon. He was honest and explained how much it would take to fix it and so he went to work. The repair work was completed efficiently and with a focus on quality. All questions were answered, and the workspace was left clean. The level of customer service provided was impressive. Steve went above and beyond to ensure complete satisfaction. Steve is wholeheartedly recommended for any heating or HVAC needs. His professionalism, expertise, and commitment to outstanding customer service are unmatched." If I could rate him 10 stars I would. Thank you for Everything Steve. read more

See all

We are just getting back into our house that was completely flooded, ducts all replaced and noticed that we had no A/C!!! And its almost 90 today. We called Steve as he had installed our system and put in a new furnace for us before. He said there was s daylight and would come over and see what he could do. He was over in less than 15min. Quickly accessed the issue was something that was caused by the flood repair when they took things apart. He fixed it, checked other things out too while he was at it real quick, and then gave us a very fair price, and was done. We highly recommend him. Thank you Steve! read more

A bit overdue, but Steve was great. On the phone, I could tell he was an expert because he knew diagnosis of a leak would take a long time and wouldn't be worth his time or my money. I actually value that because you can tell he knows his stuff. I told him to just come over and replace my refrigerant. First of all, he charges a reasonable price for it. Another big name company charged me $200 per pound. He came in way less. The other thing was we got to talking, and he mentioned he could just try injecting some sealant into the system. He also charged me a fair price for that. (another company charged $800 just to inject dye... and still couldn't find the leak). Ended up after he did that my leak stopped and A/C has been running for a year with no issues! Wouldn't hesitate to call Steven again. read more

I have nothing but praise for Steve. He replaced my entire A.C. system in my home and did a fantastic job at a price that was far below the competitors pricing. I mean he did it all,including replacing all my ductwork all by himself. He started with the ductwork tear out on Saturday, (and showed up early). Came back on Monday removed the outside unit and the inside unit, and started replacing the ductwork and installing the inside and outside units. Tuesday started early again continued marching forward Wednesday at about noon he was finished. Now we are chillin. He has a great work ethic, does flawless work and the price was extremely reasonable. Thanks again, Steve. read more

Excellent service! Steve installed two Lennox Elite AC and heating systems in a large home in Sierra Madre for us last week. He simplified what we were expecting to be a highly stressful 5 day project. The equipment arrived when he said it would, he started the job when he said he would and completed it in four days. He was quiet, respectful, clean and dependable! He showed up every morning early and worked hard. He was not on the phone or running off to do other things and leave us hanging. He didn't even stop for lunch. Before this big project we used him for a few small service and repair jobs and again he went above to be sure it was done right and at a fair price. Highly impressed and highly recommend! read more

This business has positive reviews for a reason. Fast service, to the point, moves with purpose and reasonably priced. I definitely will be calling back if I need my AC fixed in the future. read more

Steve expertly repaired our old A/C system (and at a minimal cost), something other A/C repairmen weren't able to do or who wanted to sell us systems we didn't want and at a cost of up to $20k. We were finally referred to Steve by someone at Lennox who I had dealt with years ago who told us that Steve is honest, fair, very reasonably priced, an expert at repairing and installing Lennox units, and that Steve is so honest that he won't try to do any unnecessary repairs. So, Steve ended up saving us up t0 $20K by fixing our A/C system for a mere $500. It was Steve who informed us that all we really needed was a new blower part and that our system is an excellent system that still has many more years of available excellent service left in it. Steve got our old A/C working wonderfully and quickly. Steve was professional, courteous, and an absolute pleasure to deal with. We're so thrilled we found such an excellent, knowledgeable, honest, reasonably priced A/C and furnace repairman in Steve that we can now relax knowing that we have an expert who we can trust. He really is that good and truly exceptional! read more

Steve has been our automatic go to for years, the most recent service earlier today 2-13-23, to replace our old central ac/heater thermostat after a long cold night without any heat. He responded almost immediately this morning, serviced our unit, installed a new thermostat, checked the whole system and, as always, charged us a fair, honest price for service and materials, and did it all with his always gracious and personal manner of interacting with me and my wife. We love Steve and all the competent service he has provided at our home over many years! read more

My neighbor recommended Steve and I had a very pleasant experience. I called him and within 30 mins he was at my house to check up on my heater, told what the problem was, ordered a part and next day my heater was up and running at a fair price. Very friendly professional I would definitely recommend him read more

I have nothing but praise for Steve. He replaced my entire HVAC system in my home and did a fantastic job. He has a great work ethic, does flawless work and the price was reasonable. thanks again, Steve read more

Steve saved the day for me. On one of the hottest days of the year, my AC compressor went out. Text my regular AC guy, no reply..... called another Steve AC.......sorry we are booked for the week! WHAT!?!? Called ALTA RANCHO and Steve picked up the phone. Told him the problem........text me ur address and I will be there in about an hour......and he was. Diagnosed the problem and had the replacement part with him. AC back up and running. Very reasonable price considering the current environment and demand. Thanks Steve! read more

Steve is hands-down the most knowledgeable, professional and hard working home expert I've ever had in my home. Very responsive and does top-notch work at a fair price. He installed an A/C and heating system in my home about 10 years ago. It works well and is easy to operate (WiFi-enabled). Steve himself services the system for routine maintenance or if it breaks down. Repair has been required only a couple of times in 10 years at a cost of $100 or less, and Steve comes out same- or next-day. I highly recommend Steve and Alta Rancho to keep anyone reliably cool through many summers at a good price. read more

I would highly recommend I'll Alta Rancho. Call them on Saturday morning and we were up and running again in just a couple of hours. The technician identified the problem quickly and the price was lower than I expected as well. They did a great job. read more

Saturday afternoon, over 100 degrees outside, our AC blew a capacitor (again). 3pm, after calling several companies, the soonest would get back to us Monday, I made a last attempt and called Alta Rancho Air based on their great NextDoor reviews. Steve immediately picked up the phone while he was working on another job. After a knowledgeable diagnosis, our air conditioner was repaired with a superior quality capacitor by 4pm, one hour after I had placed the call. Anyone who has tried to contact an HVAC company on a hot, summer weekend afternoon knows how remarkable this story is. Highly recommend this company. read more

"You call on a Sunday Night!" Of course I call on a Sunday night, it's when we found the problem! And if you don't want to work on a Sunday night don't answer your phone!!! "I tell you what to do, Get a Man...". GET A MAN! Kiss my butt! I don't know where you come from, but women can do all kinds of things beside make babies and cook dinner!! I can't believe you are a business owner! You must only have male customers, I can't imagine any self respecting women letting you in their house! read more

Great response time and got right to the problem! Fast, friendly, and affordable! We will call him again if we need service!

Steve gave us excellent service. He was friendly, professional, and his prices were fair. He responded promptly. We would use him again and recommend his services to anyone in need of a/c repair. read more

I can't say enough! I have used Steve twice now, once about 2 years ago for my AC unit and today again for the furnace. He is very professional and knowledgeable. Will not over charge for things you don't need. An honest man! My unit is old and he has been able to fix the issues each time. Thank you!! read more

Our A/C went out the other day when we were in the middle of a little heat wave. I like to use local business when I need something so I looked for Heating and Air repair in Rancho Cucamonga and found Alta. I noticed a 5 star rating and really good reviews so I called and was able to get an appointment for the next day in the afternoon. Steve the owner showed just as promised and even called ahead to let me know he was on his way. He immediately started working on the condenser found the problem relatively quickly and gave me a few options to make the repair. I choose the most expensive repair well under $200! :) The A/C works perfectly again. I found Steve to be honest, knowledgeable, efficient, and extremely fair pricing. I will recommend him to anyone in need in need of repairs. read more

Wow, I just can't say enough about the great service I got with Alta Rancho. They were able to come by the same day I called and had the issue fixed in less than a half an hour. Last spring our furnace stopped blowing warm air. Just after it happened my husband had a heating company come out and give us a quote. Their estimate was for more than $800 because they said the problem required them to replace much of the unit. Luckily, it was late enough in the year we weren't in a hurry, so we put off getting it fixed because with what they told us, we figured it was going to be a major expense. Deciding that I probably wanted to get more than one estimate before getting the repairs done, I called Alta Rancho and spoke to Steve. After performing a thorough inspection, Steve said it probably just needed a good cleaning. (We have several pets and the filter wasn't the right size so fur had accumulated in the motor which probably caused it to overheat and shut off.) He vacuumed everything out, put in a new filter, tested the system, and still only charged us a $70 basic service fee. He also took the time to answer some questions I had about installing A/C, explained what parts on the unit would probably need to be ungraded and why. Just talking to him you can tell this guy really knows his trade, and isn't out to make a fast buck. It's been several days now and our furnace is working great. I'm so glad I gave them a call and have put them on my calendar to schedule us for another round of maintenance next year. I would highly recommend them to anyone. read more

Steve installed an AC for us in Palm Springs and really went the extra mile. Service was timely, thorough and outstanding. I highly recommend Alta Rancho! read more

Steve is very reliable and trustworthy. He put a new system in our house and we love it. Have had it a few years now without any issues whatsoever. Steve cleaned up after he was done and answered any questions we may have had. I strongly recommend his company and his work product. read more

Steve is honest and does a great job. Very hard to find an honest vender today... Coming from a guy who is weary of scammers i feel secure and confident that Steve is fair, honest, and does a great job. This is how yiu do business. Thank you Steve read more

Phenomenal service! Will not go with anyone else. Fast, easy, great prices, honest. Steve was polite on the phone, straight forward with every aspect of the service and was great with family pets. Got us out of a really hot situation! read more

Wow! I seen him out at a house down the street and asked if he could look at my heater, He came over looked at it adjusted a few things cleaned a couple things and now works great. Super honest guy and really knowledgeable about trouble shooting. Thanks for helping out on such a quick notice and being honest with me. Keep up the great work! Highly recommended read more

Steve has been servicing my central heat/air conditioning since it was first installed, years ago. Always superior work and zero issues. I highly recommend Alta~Rancho!! read more

I called Steve in the middle of the hottest day of the year, and I was surprised a rare honest business, he said he would attempt to squeeze me Into his schedule but for a diagnosis, not repairs because it was too late at night for parts. He didn't attempt to sell me EXTRA services or charge me extra because of the heat like most places on yelp that I contacted prior. I had several businesses try to charge me for Freon, without ever seeing my hvac unit. It's a closed system so it cannot need Freon unless there is a leak !!, others tried to charge me OT because it was a weekend!!,, Thank You for being honest and actually diagnosing my system, I was quoted several hundred dollars by multiple places, it was a capacitor that had gone bad and blew the breaker. Steve repaired my system for under a hundred bucks !!! read more

I cannot praise Alta Rancho A/C enough. You get punctual, straightforward and fast response and service from Steve. You really see what professional service means when Steve comes by. Our A/C was down and he was able to identify and problem and fixed it in less than 30min or so. He even noticed some wiring issues while fixing the problem and made adjustments on the spot. That showed how much he really cared about his profession. Thank you! read more

Very satisfied with my replacement AC unit. Not only was the installation clean but the prices were better than every other quote I got.

Thank you Steve for coming to the rescue in fixing my AC when we needed it the most great job !!!

Called Steve at Alta Rancho a/c to repair a leaky air conditioning duct. We made an appointment and he came right on time. He brought everything needed to make the repair so it was done that day. Price was half of the competition. He's been to my house several times in the past and he is always honest and fair, and he knows what he's doing. I'll always call Steve for all my air-conditioning and heating needs. read more

Excellent - quick and efficient service. Our A/C went out on one of the hottest weekends of the year. Steve worked us into his Sunday schedule and had us up and running in less than 15 minutes after arriving. We HIGHLY recommend!!! read more

I highly recommend Alta Rancho A/C. Steve was awesome. He answered his phone, came out that day, was no non-sense, cool and had very reasonable prices. I highly recommend!! read more

Will be my first choice from now on for A/C service! Very professional and reasonable. Simple fix for my issue. A lot of other guys could have added a lot more to the bill but he was honest. Definitely recommend for all your heating and A/C issues. Quick edit. Couple of days later another issue popped up with a simple fix. Steve actually returned a text on a saturday night at 9 pm then called me back and walked me through it! Cant say enough good things about this guy! read more

I can't say enough about the quality of work this guys does. And he stands behind his work 100%. First found him online on a yahoo search a few years back, and keep calling him back to keep my 30+ year old a/c unit alive and running. Whenever there was a repair on warranty work, he has stood behind his job. Always on time, and you can set up an appointment where he'll arrive on time. read more

I called Alta Rancho at 3:30 pm, when our a/c stopped working, and Steven arrived at 5:00 pm. He diagnosed the problems, quoted me a price, proceeded to fix the a/c so that it cools better than it ever has, and was done by 5:40. Wow! All this on the hottest day of the year. I am really impressed, and will definitely use this company again. read more

Alta Rancho is absolutely the best there is when it comes to repairs and/or installation of heating or A/C. Everything the other reviews say are true. We have used Alta Rancho and Steve for many years for our twice yearly maintenance of our heater and A/C as well as for the inevitable emergencies that come up with home ownership. Steve is great. Fair, reliable, smart, honest, nice and he really knows what he's doing. Look no farther if you need someone to install, repair or maintain at your home. Wish we could give him more than 5 stars!!! read more
