    We had our outdated ductwork replaced by 1st Choice in 2024, and the experience has been…read moreconsistently great ever since. Every team member we've interacted with has been kind, professional, and genuinely respectful. Beyond simply being the company we liked most, their quote was also very competitive. In the two years since the installation, we've needed a few airflow adjustments, and each time the process has been easy-scheduling is smooth, and the work is handled efficiently and without any hassle. It's refreshing that their crew is alway, literally always, happy to answer questions, explain things, etc.

    I rarely write reviews but 1st Choice Heating and Air genuinely earned this one…read more We did a lot of research before making our decision. Multiple quotes, comparing equipment, warranties, pricing, all of it. At the end of that entire process 1st Choice was not just the best value we found, they were the best overall experience by a long shot. James the owner was involved from day one and that made all the difference. He was honest, straightforward and actually cared about getting us the right solution for our home. Not just the most expensive option or the quickest sale. The right one. That kind of integrity is honestly hard to find. The installation crew was excellent. Professional, efficient, clean and clearly very skilled at what they do. It was a complex job and they executed it flawlessly. They treated our home with respect throughout the entire process. We had a comfort problem in our home that had been going on for years and no one had ever properly addressed it. 1st Choice figured it out immediately, proposed the right fix and delivered exactly what they said they would. That problem is completely gone now. Every single interaction from the first call to the final walkthrough reminded me of what great service is supposed to look like. Responsive, honest, fair and genuinely excellent at their craft. If you are in South OC and need any HVAC work done these are your people. I cannot recommend them enough.

He was patient in explaining the work being done, sharing new technologies that are available and answering questions (especially since our AC system is on the older side). The price was reasonable for the performed and Brent's expertise gave us confidence that our AC will work smoothly when we need it. I also appreciate how he took the extra step to keep our home clean by using shoe covers. We continue to appreciate the service that Mission Viejo provides to keep our HVAC running smoothly!

The good news is I can report several months (almost a year now) later everything is working great. On July 4th my air conditioner decided it wanted it's independence! I reached out via Yelp to few companies, I truly was not expecting anyone to answer or return my call during the holiday but much to my surprise Mission Viejo Heating & Air did! I spoke with John - no rushed phone call, even on a holiday! John came to my house within a day or so, again it was a holiday weekend. John reviewed all of options in detail - he was professional, knowledgeable, polite - everything you hope for when working with a larger expense for your home and don't know a lot about it! Leo (main installer) was amazing - hard working, accommodating, and very knowledgeable! Poor guy was in my attic, which felt like it was 120+ degrees, for hours! I did recently reach out for a for a service call out. I wanted to discuss a few other options that were originally discussed but at the time I waited on. Gabby took care of scheduling me - great customer service, polite, and considerate of my request and needs. Martin came out to address my later service call request, he was on time, professional and informative. He reviewed some options with me, and spent time answering all my "is this possible, and what if" questions (and trust me I have them). We had new carpet installed recently and he made sure to wear booties - so considerate. When you have situations in your home that need immediate attention, I understand the stress and time constraints you can be under to get repairs in a timely manner - you must reach out to this company! Believe me, I do my homework - I can't recommend Mission Viejo Heating and Air enough!

    Excellent experience thus far for the following reasons:…read more 1. SERVICE 2. DIAGNOSTIC ANALYSIS 3. TRANSPARENCY 4. CLEAR COMMUNICATION 5. REPAIR OPTIONS WITH ELIGIBLE DISCOUNTS 6. PUNCTUALITY 7. THOROUGH EVALUATION We met with the following specialists: SEAN O'HARA (AC repair) - AC stopped emitting cool air. Fixed issue w/ filter repair. ALFRED BIRNHAUPL (AC leak repair) - Fixed pipe leak from AC and completed comprehensive assessment of our dysfunctional zoning system. DOMENICK ALONGE (project manager) - Reviewed findings from Alfred, provided detailed indication of issues and resolution options with several quotes. Here's why our experience has been superior to previous companies: All three specialists were not only punctual, friendly, and courteous, but they took their time to evaluate our issues in CLEAR layman terms corroborated by photos, and showing us exactly where the problems were in person. We previously obtained a quote from a large corporate company and was left feeling dumbfounded and stressed as they described the nature of our problem in engineering, technical jargon that made absolutely no sense, including astronomical quotes without explanation of the work entailed. We continued experiencing intermittent issues with our AC and heater so we called Friends & Family based on their excellent reviews. This time around, with Friends & Family, we left feeling knowledgeable and reassured, with reasonable quotes including various discount eligibility. We didn't feel pressured by them to choose one route vs. the other; rather, gained the information we needed to make an informed decision that would prevent such issues in the future. Overall, their attention to detail, ability to explain the issues and resolution routes in simple, concrete terms, were far superior than the preceding company. They exceeded our expectations and we much appreciated their patience and openness to answering all our questions. I also want to mention that I was gardening when SEAN was fixing our AC. He saw me struggling to dig a hole for my plant and volitionally offered to help me. He took the extra time to dig the hole for me, exemplifying his genuine kindness and generosity! Similarly, my kids were running amuck and screaming and shouting while I attempted to maintain a conversation with ALFRED. He was very understanding and continued to engage in conversation, appearing unbothered by the chaos with a pleasant disposition. Lastly, DOMENICK was appointed on the day of our son's birthday. He related to us interpersonally and even helped assemble my son's new Radio Flyer bike! I told him that Sean also helped me garden and we laughed about how Friends & Family is a "one-stop shop." Given everything I mentioned, we're excited to have our overdue AC/heater system fully repaired by Friends & Family. We can't wait for our longstanding issues to be behind us, and we anticipate leaving an updated review once the work is complete!

It went out so I had to shell up the big bucks for it.

    We had an excellent experience with JMartin Indoor Air Quality, LLC. I will post separate reviews…read morefor each individual involved in the process of selecting and working with JMartin. Jesus did the free cinsultation to address our problem. He did an excellent job representing JMartin throughout the process. He took the time to clearly explain the differences between the various systems and helped us understand why certain options made more sense for our needs. What stood out most was that we never felt oversold. He was honest about what we needed now, what could wait until later, and even what we should avoid doing and why. His attention to detail and knowledge of the products and design process reflected the high level of service JMartin aims to provide. He also identified a concern that other vendors missed, which gave us additional confidence in his expertise and in proceeding with JMartin. He was able to secure a price lock for a project we plan to do later in the year, ensuring we won't be affected by the upcoming price increase. Shay completed our first scheduled maintenance within the promised timeframe and was both informative and knowledgeable during the visit. He communicated clearly, answered questions thoroughly, and demonstrated technical understanding. His professionalism and efficiency reflected positively on the company. Michael and Frankie performed the scope of work. They removed and replaced all of our air ducts, opened up the intake grill, and installed chicken wire in the outdoor furnace. From start to finish, they were professional, respectful, and incredibly thorough. They arrived within the promised timeframe, wore boots and protected our floors, and completely cleared out the attic before designing a much more efficient airflow duct system. Everything was neatly suspended instead of left on the attic floor, and they even replaced all the vents. What really stood out was their attitude and communication. Michael and Frankie took the time to explain everything clearly and patiently answered all of our questions without ever making us feel like we were bothering them. They were always friendly, helpful, and easy to talk to. When the job was finished, they cleaned everything up perfectly and even hauled away all the old ducting bagged up, leaving absolutely no trash behind. That level of care and respect for our home was truly appreciated. I highly recommend JMartin Indoor Air Quality, LLC, and especially the Michael & Frankie team. Outstanding workmanship, excellent customer service, and genuinely talented respectful people. We will also be working with JMartin in the future when it's time to deep-clean and insulate the attic. I am glad we found them!

I had low expectations as my previous technician with a different company from last year barely did anything and did not even check our drain line inside the home. McShane was our technician and he's the reason I'm even leaving a 5 star review. He explained what he was doing and answered all my questions. He was respectful of the property, used shoe covers before entering, and asked permission before moving things around. You notice those little things when you've had a bad experience in the past. I would say the value is also worth it. It was $85 for the tune-up. I was obviously looking for something cheaper but you get what you pay for. Overall great service!!

We had a relatively complex HVAC issue that required a follow up visit. The owner, Drew H., was highly responsive and reliable from the very beginning of the project to the end. When a minor miscommunication arose regarding the labor charge for the final replacement part, he quickly stepped in to clarify. They honored their original promise and completed the work at no extra cost. It is good to work with a contractor that stands by their word, sticks to their estimates, and takes responsibility for the final result. Highly recommended for their professionalism.
