I contacted Evolution because I was budgeting to replace my old and broken AC. They responded to my message on Yelp very quickly and got me an appointment at my earliest convenience. When Jeff visited my house for an estimate, he dropped so much information about the market price, other contractors' schemes, and the competence of his team. Frankly, I did not believe what he was saying at the face value, so I contacted other companies for their inputs. Turns out, what he was saying was 100% right. Other contractors tried to use the exact tactics that Jeff warned me about and tried to scam me by providing inferior products and services. One prominent company that I shall not name even contacted me back desperately for the job once they learned Jeff and Evolution were in the bid. This made me fully trust Evolution and give them the job. Once I was committed, everything was done smoothly and promptly. Diego and the technicians came exactly on time and got to work right away. The crews are extremely hardworking and knowledgeable. They answered all the questions I had and fulfilled my additional requests without hesitance. Also, this was the first contractor that I had in my house who did not completely trash my place while working. They delicately wrapped my master closet so that they do not ruin my clothes while working in the attic. They cleaned pretty well before they left too; I only did light vacuuming because the place was so clean after they left. They finished the complete replacement of my AC unit within 5 hours. They did such an awesome job as you can see in the picture. I am so glad that I reached out to Evolution. They saved me a lot of headaches by making everything simple and quick! read more

Outstanding service! We have had Diego from Evolution Heating and Air Conditioning do small HVAC Repair projects at our house. He was very responsive, prompt And professional. This week we had central air conditioning installed at our home.The crew, led by Tim Delgado, was amazing! Job was finished within hours and the system works perfectly. The entire crew arrived promptly, prepared with all necessary materials, and were remarkably courteous and professional. I would not consider anyone but Evolution Heating and A/C conditioning for any of our HVAC needs. read more

We needed a new HVAC system, so we started getting quotes from contractors. Diego at Evolution Air gave us several options at a reasonable competitive price, and in a shorter timeline than the other companies we talked to. Everyone we dealt with at Evolution Air was friendly, courteous, and very professional. Rose kept us in the loop as to how the project was going, and she was very responsive to any questions or concerns we had. The installation itself was completed quickly and without any problems. We're very happy with the result. Evolution Air is, without a doubt, the best contractor we've ever worked with. You can trust them to get the job done right. read more

Evolution heating and air installed our new ac unit, relocated the new furnace and installed our tankless water heater and redid all the ducting. Raul and his team were super friendly, respectful, punctual and got the job done within 2 days. The price was great for the amount of work done and material used. We are just starting our remodel journey and we could not be more pleased with the work the team did. You will not be disappointed read more

Raul, Luis, and Aram showed up at the house first thing in the morning, 7:30am and was done with the HVAC installation before Noon! Can't ask for a more professional and nicer group of guys working at your house. Quite impressed with how well they worked together. It's refreshing to see real team work on display in this day and age. I will definitely recommend this company if my neighbors are looking for exceptional installation service with a fair price. Do your homework and get your quotes then call Evolution like I did and they will close the deal that you'll be happy with. Now we're ready for the summer heat thanks to Evolution! read more

I highly recommend Evolution Heating and Air. Diego and team have installed HVAC units at two of my properties and a mini split in my garage. I couldn't be happier with the work performed. Prices are competitive and their service is spectacular. read more

Evolution heating air was here today to work on my air conditioning. Eddie, the technician definitely knew what he was doing. I would recommend evolution to anyone for their heating and air conditioning needs. Knowledgeable and efficient service. 5 star read more

This was our first experience with getting an A/C as well as replacing our furnace. After shopping around we choose Evolution, not only for the cost but more so because of their professionalism-- cost was great too!! The technicians were very knowledgeable and explained things as they went, they were professional, respectful and very clean, they used tarps to cover the area and shoe covers. The work was mainly completed in one day and part of another day to finish up and run test. Once they completed the job they went over how the units work and let us know that if we had any questions they were just a call away. We are very happy with their service and would definitely recommend. Thank you to all of them. read more

The wife wanted a cool house this year, and due to the pandemic, funding is crucial, so the project's end-goal was to get everything done for a reasonable price. Jeff with Evolution Heating and Air Conditioning was very professional and responsive to inquiries. For the project that needed to be done at my house, Jeff gave me a very competitive quote (I got 7 quotes total from various contractors). Before I sign the contract on a Sunday afternoon, Jeff laid out the timeline on what will happen. He said, and I quote, "If you agree, I can have the abatement company come out tomorrow (Monday) at 11 am. They will remove all asbestos ducting. My guys Diego, Raul, and their crew, who I have worked with for 20s years, will come out the following day (Tuesday) between 8 am - 9 am to start the install. They should complete everything that day or by Wednesday afternoon." The man was true to his words! Literally, everything transpired exactly as he promised! Diego, Raul, and the team complete the install within 1 day!!! Not only were they punctual, and did an exceptional install. It is amazing the amount of work the team was accomplished in a few day. Simply amazing! Thank you Jeff, Diego, Raul, and crew! read more

Finally found a company who is really honest and knowledgeable. Very impressed and happy with our new air conditioner! Diego (I believe is the owner)and his crew were able to spot issue and quickly dissolve the problem and replace a new AC unit. They beat a couple competitors price and I am very happy! Diego was very informative and communicated so well to make sure everything happened in a timely manner. The entire process from scheduling the estimate to approving the work to completing the job only took a few days. I would definitely recommend and call them again for any other A/C issue! I will for sure refer them to my family and friends. Highly recommended! read more

Evolution Heating and Air Conditioning were amazing to work with! Their sales manager, Jeff Kieffer, came out to give me a quote same day and then gave me the price on the spot. After getting 2 more quotes from other companies, I felt like they were the most professional and reasonably priced. They came out right away to get the job started. We got all new ducts, air conditioning unit, and furnace. It was a huge job that took them 2 days to complete but other companies said 3-4 days. Angel, Aram, Jesse, Ulises, Ramon, and Gilbert were all here right at 9am or before. They were respectful, professional, and cleaned up so well after themselves. I highly recommend this company! read more

So happy with their service. Fair, competitive prices and they went above and beyond to accommodate our needs in a timely manner. Highly recommend. read more

I've experienced such great service with Evolution. They have executed in both excellent customer service and delivery of their product with a great price and warranty. We were so happy with our service that we immediately called to service another unit we had (installed previously with different vendor) within a week. We will definitely use for new installs or for any service needs. Thanks again! read more

My heater was having problems not getting hot and failing to keep the house warm. The first tech arrived soon after I requested service, he came and quickly identified one issue. He had to return to get parts, and another tech returned in a couple of hours to install it. Overnight, we found the heater was still unable to remain running long enough to warm our house. I called early in the morning around 6:30 am, and the person who answered helped me get someone out to our house. The same tech arrived around 7:15 am. He was able to determine that a sensor required cleaning, and that seems to have solved all of the problems. Easy place to do business with. read more

I worked with Evolution in April 2023. The first thing I loved in this company is that their representative (Brian) could come out the same day. Prompt, scheduled for 6pm, he was at 6pm. Brian looked very knowledgeable, which is not always the case with AC guys reps. Everything we agreed on was done. In general, I was very happy. There was nothing what we agreed and was not done. The only recommendation I would give to Evolution is to inform the installers better about what they have to do at the particular object. We had some agreements with Brian, which were not passed to the installers and I had to explain again about some specific requests. read more

We met Jeff Keiffer, General Sales Manager, at the Anaheim Home & Garden Show on Friday, April 21st. We had had our kitchen remodel about 10 years ago. We failed to install an exhaust system that vented to the outside at that time. Big, big mistake. Having an internal vent with filters isn't nearly as effective as venting outside. 10 years of smelling last night's dinner in the morning was enough to convince us of that. We met with Jeff at the show, I explained the issue and he quoted me a very,very fair price. Jeff also said the technicians would be at my house Monday, April 23rd at 3:00 pm so I wouldn't have to take the day off from work myself. Over the weekend we did take multiple pictures of the stove and area around it, the attic crawl space and the roof. We wanted to make sure that enough information was available to account for any situation. Tony and Eric showed up right at 3:00. Two very nice people that put down cloth tarps in both our kitchen around where they'd be working and under the trap door into the attic to catch any debris. 2 hours or so later I had a vent over my stove to the outside. They left my kitchen as clean as it was when they got there and were just a pleasure to have working in our home. To us, one of the signs that a good job was done is that you cannot notice any changes to your environment when the work is completed. Our kitchen looks the same except, I can no longer tell you what we had for dinner the night before just by walking through it. Thank you Jeff,Tony & Eric. You all did a fantastic job and are now our go to HVAC team. read more

The owner, Diego, crew member Raul, and the rest of the team did a fantastic job in replacing our A/C with the most up to date technology (20 sheer American Standard) with variable speed energy saving 4 ton each, two units. They were on time, curtious, clean, and worked very efficiently as a team. I would go with them any time. read more

After the first inspection, the inspector requested a list to be corected, which was strict. I sent it to Rose, office manager, she and the installation team had resposed quickly and scheduled next inspection within a week. Finally, it was passed the city final inspection. That high responsibility and excellent service after sales! Thank you everyone! read more

Evolution is awesome! From the workers to the people who answered the phones, they are just the best business to work with. We will definitely use Evolution again in the future. They did an amazing job with the installation and we love the heat this winter. Tim and Angel were very professional and super respectful. They were on time and always kept me updated throughout the process. They did an excellent job of cleaning up each day before they left. We have had a contractor who left horrible messes. We had a complicated area and they were able to make it work out the way we wanted. I highly recommend using Evolution heating and air! read more

Jeff Kieffer General Sales Manager for Evolution Heating and AC came to our home on Wednesday. We were very pleased with the quote we received from him it was thousands less and was for better equipment. Jeff doesn't try to "upsell" He gives you on honest fair estimate. We sign up on the spot! The Evolution installation crew were FANTASTIC! they had the old units out and the new units in, in one day and this included replacing all of our (hanging) ducting, registers and returns. Heck, they even added an attic light and switch at no extra charge. They guys were very friendly, we couldn't have asked for a better crew. After they were finished except for better air circulation, heating and air condition you wouldn't even know they had been here. Their clean up was top notch. We highly recommend Evolution Heating and Air Conditioning when it comes to replacing your old inefficient equipment. Below are before and after photos read more

Excellent customer service with high quality of installation service. Installers demonstrated a strong work ethic and were professional!

Evolution Heating and Air did an amazing job with our installation! They were very helpful with all our paperwork and inspections and I would highly recommend them to anyone looking for an HVAC vendor. read more

Highly recommend this company! I received 4 different quotes and what made Evolution standout was Jeff (sales manager). He is a wealth of knowledge. Right away he made great recommendations that no one else had mentioned and didn't try to up sale us to a unit that was unnecessary. He was honest and told us it was a waste of money, but we could if we wanted. He also offered the best price for all the work done at our house. The crew was great! Very respectful, polite,and friendly. Really enjoyed Angel, Tim, and Gilbert! Worked hard the entire time to get it done in two days. Then Jeff was awesome by helping find some that could do some touch up painting and drywall fixes! All of this within days of New Years!!! Overall great experience. I am recommending to friends. read more

In mid December our heater stop working, so based on yelp rating I decided to go with free estimate that company has. Brian is highly qualified and explained issues which cause problem in our heater and provided few options for new one. We decided to go with heat pump. Work was done really quick,even though it was end of the year,they managed to send a crew to install new AC/heater so we can celebrate Xmas in worm house Crew was very delicate, they did work very quick and clean after the working area,so I had nothing to do after them. Rose, the manager is super supportive and here for you anytime. For sure will recommend this company's service to all my friends and family. read more

Called and got many quotes, but the best was from Evolution, it was a very pleasant experience from Brian who came out to quote, to the guys that came to install my new AC. Very happy with Evolution and very professional and the employees extremely respectful to my home. I would highly recommend them and will refer them to others that are in need of a repair or replacement AC. Thank you again and including Rose who scheduled everything. A big thanks! read more

Quick and efficient. Jeff Keiffer has been my salesman for many years. He arrives with professional efficiency. He set an appointment, arrived on time and set me up for 2 air-conditioning systems where none existed. One, in my rental was set up with an interest free loan for 2 years, I have done this before with Jeff. It makes the cost very manageable in a rental. He quoted me for both properties on a Saturday and both places were installed on Tuesday. The first crew texted and arrived and 8:30AM, as planned. Diego is the lead, Raul, Ramon, Gilbert, Luis and Aram, arrived and were able to troubleshoot concerns for electrical hook up and placement. Both residences were completed by 4PM. I couldn't be more pleased. read more

I can't begin to explain the happiness I feel in knowing I chose an HVAC company as honest and dependable as EVOLUTION HEATING AND AIR. Jeff walked me through the ropes and gave me options for which I am grateful. Needless to say I chose this company and Couldn't be happier. This year I can't wait for the summer because I know I'll have the best upgraded unit on my block! read more

Overall I am very happy with the results from Evolution. I feel like we got a great price, they got us properly sized A/C units for our spaces, the installers were very friendly, courteous and respectful. This was a split system and these guys seemed very experienced dealing with these systems. Jeff gave good honest advice about what would likely serve us best and give the best value. The installation went okay but did run into a few issues and the exterior ended up a little messier than we had initially discussed because it just wasn't going to work out how it was originally planned. Took longer than they had anticipated and I feel like because of that they didn't spend as much time cleaning up and making sure everything was put back as they should have. Their drywall guy came to clean up some things that had to be opened up and patched and his team did an excellent job finishing and making it look better than it started. read more

I meant to write a review for a few weeks now. At this point, I also gave up on taking pictures. I will append the pictures later, once I get some free time from work. We recently requested estimates on a complete new HVAC systems. We received three different quotes and decided to go with Evolution. We made the decision based on: (1) Evolution is an authorized American Standard dealer and installer (2) Knowledge represented by Jeff and his logical/no-nonsense recommendation on equipment (3) Overall warranty, equipment model proposed, and cost. What we received: (1) Complete HVAC systems including installation (2) Moving the air handler from down stair closet into the attic (including closing up the the hallway cabinets from the attic) (3) All new duct work for air flow efficiency (4) All new registers with dual directional adjustment (5) Nest Smart thermostat (6) Dry wall re-patch and painting After a few weeks of using the system, we just can't be any happier. We opted for a Heat pump due to spare electricity from our solar panels. The variable speed air handler paired with the Heat pump produced a gradual heat and cooling that is efficient and comfortable. Jeff's crew really did a great job. They are professional, efficient and very clean during and after the project. We are really glad we went with Evolution on this home improvement. Biggest shout out to the team. read more

Fantastic service, fully recommended. Our 40 year old A/C finally gave up on a Friday evening before a heat wave. At a friend's recommendation, I called Jeff on Saturday and he was able to come out that day to inspect, measure, and sign paperwork. I already had a proposal from another company so I knew Evolution's price was very competitive. Tim and Angel came out that Monday and installed our new furnace, coil, and condenser. They were friendly, respectful of our home, and got the job completed that day. After a couple weeks, we thought our system seemed a little loud, so Eddie came out and inspected the system and showed me how I could control the fan speed. I felt silly for bringing him all the way out here just to show me a switch, but Eddie was friendly and happy to help out. Our new A/C cools the house quickly and looks like it's reducing our summer power bills by 40-50%. read more

We called initially to get some quotes for mini splits, Jeff came by and sold us a complete HVAC system. That's how good he is. He clearly and confidently laid out what they had to offer and made it super simple for my wife and I to make the jump. We trusted his recommendations because we sat through a few sales pitches with other HVAC companies a few months back that basically scared us off. Jeff came in and didn't waste our time. Once we confirmed, Jeff gave us the game plan. They started the next morning. Wow. The team arrived the next morning promptly and clearly communicated what the day's goals were. Martin, Luis, Adam, Raul, and Ulysses were ON POINT. They came in and did an amazing job and were more than willing to answer any questions I had. They checked in to make sure to get my input on vent placement and even let me take sneak peaks on progress. First day- boom! Insane amount of work for a day. They closed out and made sure to clean up. They were super courteous and made sure our day wasn't disrupted (pregnant wife was super impressed). Second day - closed out super strong! System was perfect. Diego came by to check in and tee up the drywall guy (Adan, who was also great). They popped in the Nest and installed a light in the attic. At the end, they left the place spotless. We highly recommend Evolution. My wife and I still can't believe how painless it was --we've had numerous work done on our house so we know how disruptive, stressful, and messy these things can be. We're actively recommending Evolution to whomever would listen!!! We will definitely go back to them with anything we want to tackle next. 10/10 would recommend read more

We met Jeff at the Riverside Home Show. He came out the very next day to give us a quote. I was determined to get 3-4 company quotes before we proceeded. However, Jeff is such a good salesman and he gave us what we considered to be a great price, and our new split system would be installed within a week... So, we broke our rule and went with Evolution without other quotes. After the job was done I was assured by several neighbors and our complex manager that we would never have been able to get such a great price on such quality equipment from any of the companies they had recommended to us. Whew! The installers were friendly and worked very hard for 2 days. They had challenges like drilling thru very thick stone walls and removing a wall AC unit that had been installed to survive the apocalypse. They showed us how to work everything in a thorough manner. All 3 separate units look good inside/out and work perfectly. They are so quiet and heat/cool quickly. The installers did an excellent clean up. Overall, we were very happy and several neighbors immediately commented on what a good job they had done and asked for Jeff's contact info. The ultimate compliment. read more

I've learned a couple of things this summer. One, you don't ever want your A/C to breakdown if you live in the I.E. The heat is on another level out here. I couldn't sleep, I couldn't clean, I couldn't cook without breaking into a sweaty mess. Two, don't go with the big A/C company, give your local family business a call chances are they will hook you up. I almost made that mistake and I'm so glad I called Evolution Heat & Air Conditioning. Rose took care of me after hours and made special arrangements for someone to go out the following day. They offered me a great deal. After that, everything was a breeze. They offered financing which made this decision easier. Within minutes I had my approval. Rose ordered the units compatible for my condo and the following day at 8 AM, Tony and Erick were knocking on my door ready to get me back to loving life. Tony & Erick worked diligently. They were knowledgeable, professional and respectful of my property. Installation was smooth as it could be and I'm loving my new Nest thermostat. I'm back to loving life and it couldn't come at better timing with this current heatwave. Thank you Evolution! read more

I highly recommend Evolution Air. They were recommended by my friends who spoke highly of their experience with the company. I was contacted by Jeff, the general sales manager, who was very easy to work with. He came to the house and explained what I needed and offered several options of AC units and their placements. The installation crew was quickly scheduled. Ramon, Adam and Martin were organize, efficient and professional. Besides the technical part of the installation, they took great care to be clean inside and outside of the house. They answered all questions and made sure I was satisfied before they left. From start to finish the experience was great. I will recommend Evolution Air to family and friends not only for their quality products but also for their awesome personnel. read more

It was a pleasure working with Rose and Eddie. They were professional and responsive, and the issue was resolved with a fair price. Eddie took the time and showed me the heating unit and explained what some of the components did and what was the problematic issue. Highly recommended and will use again for my next HVAC needs. read more

We purchased new Heating & A/C unit through Evolution last 3/2021, very pleased with installation and units. Last night 2/2022 we had an issue with the heater not turning on, called Diego (Owner) in the morning and he immediately scheduled same day service. Eddie came out and corrected the issue and explained to us exactly what the issue was. We couldn't ask for better, faster customer service. Thank you Diego and Eddie.. read more

Evolution and all the staff have been nothing but amazing. This review is way overdue. Our home was built in 1982 and desperately needed a new a/c unit and furnace. We got the a/c and furnace replaced in the summer of 2022. Brian came out to inspect and was very knowledgeable about all the brands and sizes of the units according to our home size. Then Rose the office manager provided a quote over email that was competitive (we had 3 other companies come out for quotes). Installation was quicker than I expected and they all did a stellar job at installing and cleaning up afterwards. We also needed new ducts and although I had three other quotes, Rose gave us a discount for being a returning customer and that sealed the deal. We got the new ducts about 6 months after our a/c install. They brought 4 or 5 guys from what I could remember and did a great job and provided pictures of the before and after of our attic. I need to dig up the pictures to post but I was very pleased with the services! Fast forward to 2024, and we still remain as happy customers! We've never had any issues since the install and duct replacements and most importantly they have been super responsive when I have reached out to check on my unit to make sure it was running properly. I noticed a moldy smell and they came out to check on it and clear out my drain pipe (which was super old and probably where the smell was coming from). I love how I can talk to Rose or anyone at the office right away versus being rerouted to a call center. Turntimes on service calls have been quick; if they have someone available, they'll send them out the same day or at least a few days to at most a week later for non-urgent needs. I wish I remembered all the names but I've had Juan, Eddie, and Tim come out to the house and they all have been very efficient, informative, and respectful. Lastly, I was not charged for these follow up services!!!! I highly recommend them to anyone looking for a new unit or repair service! read more

If you're looking for a team that is professional and will get the job done, look no further! Diego and his team were absolutely AMAZING! I recently moved into my condo and my air conditioning and heater stopped working. I was looking into switching to a smart (google) thermostat also and Diego and his team (Martin and Ulisses) were able to address all my needs! I reached out to Diego on Monday and he came out Wednesday to assess my unit, (free consultation). His team was able to come the following week with the brand new unit, ready to install. They are very skillfull and worked quick and efficiently. Martin made sure everything was working and cleaned before leaving for the day. And that was so reassuring for me that they take pride in their work and stand by their product and skills. I highly highly recommend them! If you have any questions just reach out to Diego! He is very easy to talk to, friendly, and very good with communicating with you throughout the whole process! I would definitely utilize them again for future projects/repairs. read more

I have so many good words to say about Evolution Heating and Air along with the workers. We recently build a new ADU and they were there every step of the way.

They have very affordable pricing and incredible customer service and owners. Would definitely recommend to family and friends. read more
