HVAC reviews in Foothill Ranch, California

We first interacted with Eli, a highly skilled and professional individual from a local heater repair service. We quickly developed a sense of trust towards him. After a regrettable incident with Eli, we were comforted when Caden, accompanied by Logan, visited our premises in Foothill Ranch to review the conversion of our entire HVAC system to Natural Gas. The installation process went without a hitch, and the team was prompt in resolving any startup issues. All in all, they were an amazing team from a top-notch heater repair service, and our new HVAC unit works wonderfully.

I cannot express my gratitude enough for the peace of mind your team has given me. I had a terrible experience with a previous furnace repair service that was scheduled for just a routine maintenance check. They attempted to sell me services I didn't need, ruined my return duct to coerce me into paying for a costly duct cleaning, falsely claimed that mold was everywhere, and insisted that I needed to replace all my ductwork and my 8-year-old heating system (which is currently working fine). They even claimed that the outdoor unit was outputting a dangerously high voltage and would fail by the summer. Their sales tactics were excessive and the experience was dreadful. Thankfully, your team came to my aid and thoroughly inspected my entire system, reassuring me that I didn't need a new furnace - my existing one is running perfectly. If you're wary of being scammed by other companies, I highly recommend getting a second opinion from these guys. Their technicians, like Jeffrey, are incredibly professional and knowledgeable. Jeffrey knew exactly what he was doing and took the time to explain everything to me. I'm so relieved that they came to my rescue, showing me the true readings on the outdoor unit which were perfectly normal. They even went above and beyond to rectify the damage caused by the previous company to my unit in my 8-year-old Foothill Ranch home. They've won my trust and my business for good. I will always recommend them and share my past experiences so others don't fall victim to the same scams. Be wary of other companies offering 'low price maintenance specials' - such deals are often just a way to get into your home and take advantage of you. It's disheartening that there are dishonest services out there, but I'm even more thrilled to have found this team. They've restored my faith in furnace repair services. So much appreciation for their work!

My house required a complete overhaul of its heating system and the upstairs was always too warm during the hot months. Miller & Sons Home HVAC was the only company that provided a comprehensive solution for my needs. I was lucky to be eligible for a clean energy program. I can't express enough how well I was kept in the loop throughout the entire process by the team. Eli, Ralph, and Caden were prompt with their installations and they were incredibly efficient. They even took the time to clean up after their work each day. I received a top-tier heating system and, although the temperature variances aren't completely resolved, they have significantly improved. I wholeheartedly endorse Miller & Sons Home HVAC for anyone in need of heating repair or maintenance services.

Our heater stopped working late one Saturday. I had already decided to hire them for a replacement heater and air conditioner and had a meeting set up to finalize the contract and set a date for the replacement. To our surprise, they brought over space heaters to keep us cozy on Sunday morning. I signed the contract and they arranged for the replacement the very next day. Logan and Eli arrived at our home at 8:30 and had completed the job by 3:00. I can't express enough how pleased I am with their work and their exceptional efforts to ensure our comfort and fast heater system replacement.

Our furnace, which was over 30 years old, decided to break down on a Saturday. Luckily, Ralph was on standby and promptly picked up my call to the after-hours emergency service line. He showed up at our home in Foothill Ranch and managed to get our ancient furnace back up and running. Not only was Ralph polite and courteous, but he was also extremely professional. He made a swift journey back to his truck to fetch the right size hose and clamps, going above and beyond to repair our old furnace until we can find a suitable replacement. I'm excited to explore the options for a new furnace and maybe even central air conditioning. A big thank you to Ralph and the team for their assistance on a Saturday.

my heater suddenly stopped working in the middle of winter, but the technician from miller & sons home hvac arrived at my home in foothill ranch promptly. he quickly identified the issue with my 27-year-old heating unit and suggested some temporary fixes to get us through the cold season. the technician was very professional and immediately arranged for the installation of a new heating unit the following day. logan, eli, and jeffrey, who came to install the new heater, were all very professional and responsive. their pricing was reasonable and the quality of their work was exceptional. not only did they efficiently install the new heating unit, but they also left the area cleaner than it was before. i would highly recommend miller & sons home hvac for all your heater repair needs.

Our old heater was replaced two years ago and the team went above and beyond to ensure the high-efficiency furnace we desired was compatible with the unique challenges our aged house presented. They took their time to explain the trade-off between opting for a more efficient heating system and the related increased cost. Another team could have easily pushed us towards the most energy-efficient unit, especially given our interest in that direction, which would have been overkill for the climate in Foothill Ranch. Today, we had to call them as our external unit stopped functioning. They responded promptly, rectifying the issue on the same day, and the repair was covered under our warranty. Tucker was swift, meticulous, amicable, and shared valuable advice on heater maintenance. He also adhered to safety protocols by wearing a mask and maintaining social distance. I would gladly recommend this heater repair service to my friends and family.

We sought assistance from a local heating service on a Saturday when our heater wouldn't turn on. Jeffrey arrived promptly and replaced the capacitor, but unfortunately, the issue wasn't resolved. He suggested that the fan motor was defunct and that a new heater would be required. After only spending 10 minutes assessing the situation, he left us with a $210 bill and a non-functioning heater. The following day, our neighbor, who formerly worked in the same industry, decided to take a look. He reconnected the old capacitor and noticed that a wire from the fan was slightly damaged. He promptly cut the wire, stripped both ends, and hooked it back up. The heater has been functioning perfectly ever since, and it only took him 10 minutes to fix! Initially, we were unsure about using the same heating service in the future. It felt like the problem wasn't thoroughly examined and that the main objective was to sell us a new unit. However, an update to this situation made us reconsider. We received an email from Logan, who apologized for the service we received. After calling him and explaining the situation, he rectified the situation by crediting the $210 back to us. Logan, your dedication to excellent customer service is noteworthy and greatly appreciated. Despite this hiccup, we've generally experienced great service from your team in Foothill Ranch. Your actions today truly demonstrated your commitment to customer satisfaction.

Working with this furnace repair company was an absolute pleasure! I engaged their services for regular maintenance on my furnace as well as an annual fireplace checkup. The process to schedule an appointment was straightforward and the staff was incredibly helpful in providing an accurate cost estimate. Plus, everyone I spoke to was extremely friendly and knowledgeable! On the day of the service, I received a reminder text and email when the technician, Tucker, was en route. Tucker was outstanding! He was friendly, well-versed in his work, and took the time to explain the systems he was working on (as I'm a new homeowner). He also ensured the work areas were clean and gave me an in-depth overview of the invoice and the work carried out. I will undoubtedly continue using this company for all my furnace and home system maintenance needs in Foothill Ranch!

Miller & Sons Home HVAC is truly the greatest. I purchased a furnace from them a few years ago, and the installation process was impressive. The team was not only accommodating but also respectful and efficient. Recently, my furnace stopped working and they promptly sent over a technician. Eli was able to get it up and running in no time. In addition, he even supplied me with space heaters to use in the meantime. If I could, I would rate them with 20 stars. They're always kind, helpful, and timely, making them an exceptional company to rely on. When I decided to have an air-conditioning system installed, they were my first choice. Jeffrey came out and installed it in my old house. Once again, they demonstrated their kindness and punctuality. The system worked perfectly, marking my first experience with air conditioning. It was truly the best experience with them. The pricing was reasonable, adding to the overall positive experience with Miller & Sons Home HVAC.

Contacted this AC repair service due to their impressive online reviews, and they certainly lived up to the hype. They responded quickly, were honest and offered fair prices. Despite dealing with an outdated air conditioning system, they could have easily suggested we needed a completely new unit. However, Ralph and Eli made two trips to Foothill Ranch for parts and still managed to complete the job within 5-6 hours. Now, the best part is that my house is perfectly cool! I will definitely engage their services for future AC repair needs.

I recently had the pleasure of working with Logan for a heater repair, and I couldn't be more pleased! From the moment he arrived, Logan displayed professionalism and a friendly attitude that made me feel comfortable right away. He took the time to explain the repair process thoroughly and answered all my questions clearly and patiently. It was obvious that he was not only skilled but also truly passionate about his work. The detail he provided while inspecting my heater was impressive! He spotted a few minor issues that I hadn’t noticed and quickly got to work, ensuring everything was running at its best. Logan was respectful of my home, keeping everything clean and tidy before he left. I can definitely feel the improvement in my heater's performance. I highly recommend Logan for any heater repair needs. The blend of excellent service, expert knowledge, and attention to detail made this experience exceptional.

We are absolutely thrilled with our decision to hire a top-notch HVAC company to install our new furnace and central air system. The job was quite complex: they transitioned us from oil to propane, liaising with the propane company on all matters, updated and extended the ductwork throughout the house, removed the old oil tank, modernized and installed new thermostats, and incorporated a state-of-the-art central air conditioning system. Our consultant, Jeffrey, was upfront, experienced, and pragmatic during his initial home visit. Among the three companies that provided us with quotes, this one was the clear winner. One company incorrectly informed us that central air was not feasible in our home without an electrical upgrade and then quoted an exorbitant price. The second company's quote was similar to this one for a new furnace and propane conversion, but after some research, we found that the equipment this company suggested was of superior quality. The entire project was completed in 4 days, and the team exhibited utmost professionalism, courtesy, and knowledge. It was clearly evident that they are highly skilled and take pride in their work. They put in a full day's work every day. Tucker thoroughly explained everything to us, giving us options such as where to place the thermostat, despite it meaning extra work for him. He noticed an old electrical wire connecting to the furnace and recommended its replacement, assuring us it would take some extra time but was necessary. Logan's past experience in roofing even allowed us to have the furnace vent through the roof! Upon completion, they took the time to explain every component of the new systems, restoring everything to its original place and cleaning up their work areas. We highly recommend this HVAC company for their top-quality equipment, fair pricing, strong work ethic, and outstanding customer service!

I'm really happy with the heater repair service I received after a recommendation from a satisfied customer. I'm also now delighted with their work. The technician, Eli, came to repair my heater promptly, and their rates were quite affordable. He took the time to break down everything for me and was very transparent about the repairs I did and didn't need for my heater. As someone who isn't familiar with heater issues, I valued this honesty. I plan to rely on this same service for all my future heater repair needs!

i've been calling miller & sons home hvac for heater repair for years. the first time, my furnace broke down in foothill ranch on thanksgiving. i came home late with my young son and the house was only 52 degrees! i waited until morning to call, thinking a holiday service would cost extra, but it was just the normal service fee. since then, i always rely on them to fix or maintain my furnace. i also have central air here, and will be scheduling a maintenance check for that in the spring.

I'm really pleased with the furnace repair service that was assigned to me by my home warranty company. I'm beyond grateful! I couldn't have requested a more proficient service from start to finish. These professionals have visited my place twice and handled everything perfectly. They were quick to respond and arrange a service appointment. Their manners were commendable, showing respect and kindness, and they were straightforward about all aspects. One of their technicians, Tucker, was able to determine that my thermostat was not compatible with my system. He offered me valuable advice and when the time came to install the new one, he personally took care of it. This is a furnace repair service I would endorse wholeheartedly to anyone in Foothill Ranch.

The technician, Tucker, worked on the rooftop heater and conducted a thorough safety inspection, discovering a critical issue with a major heating part. Tucker's careful approach ensured that the furnace was safe to use, protecting the tenants who depend on it. The service provided went above and beyond what we expected and was much better than previous experiences with other contractors. I highly recommend this company for all heating repair needs, both commercial and residential. Great work!

We recently had a high-efficiency furnace installed in our home by a professional team. We had three different furnace repair services provide us with quotes. The team we chose was far superior compared to the other two. Logan, our main contact, visited our home thrice to evaluate what would best suit our needs. He brought along Jeffrey, a furnace installation expert, to determine if we could establish two heating zones in our home, allowing us to heat our primary living area without having to heat the entire house at all times. Logan guided us through the advantages and disadvantages of three different options, helping us make an informed decision. By the end of the process, we had built a strong sense of trust and felt confident that we were getting what we needed, not just what they wanted to sell us. The installation process went smoothly, with the team being mindful of our space and ensuring a clean environment once they were done. I would highly recommend this team to anyone in need of a furnace repair or installation service.

Eli is a true professional! He did an exceptional job during his service visit to my AC unit. His understanding and knowledge of the AC system was flawless! He went the extra mile to check my warranty, thus saving me over $250 on a capacitor replacement that was still under warranty. I would gladly recommend him to any family member or friend. As always, Miller & Sons Home HVAC shows they genuinely care about their customer, taking the time to ensure the system is operating correctly and thoroughly explaining the entire process. This service visit in Foothill Ranch was a great experience.

Miller & Sons Home HVAC did a fantastic job setting up HVAC equipment in my home and my mother's residence. The level of professionalism, meticulousness, and customer support that Jeffrey, our technician, provided was unparalleled. The equipment's quality and service were truly noteworthy! He installed a brand new furnace, an A/C system, and a separate filtration system, all of which have performed excellently! Considering everything my home required, the cost was quite reasonable. I wouldn't hesitate to suggest Miller & Sons to my friends and family. One particularly hot summer day, with storms on the way, Jeffrey dropped everything to come out and exchange the smart thermostat for a regular one, as it turned out my house wasn't compatible with smart thermostats. He even took time out of a long holiday weekend to swing by and kick-start my furnace for the first time, ensuring it was operating effectively. Everything from routine maintenance to installation and follow-ups has been superb. When it came to this significant investment in my home, I couldn't have wished for a better experience. My gratitude is immense and simply saying 'thanks' doesn't begin to express it!

i recently had furnace repair work done at my home in foothill ranch and i can't say enough good things about the whole experience from start to finish! everyone i spoke to was amazing, including caden, tucker, and logan. the team was responsive, knowledgeable, professional, and really went above and beyond. they got my furnace fixed way earlier than i expected, which was such a nice surprise. the technicians showed up on time, were very friendly, and did a fantastic job. they even cleaned everything up afterward! when i had a question about a noise my furnace was making, they sent someone over within an hour who explained everything clearly. i've never had such a great experience with any contractor before. they also took care of all the paperwork i needed for my rebate right away. professional, quick, and super helpful—i highly recommend them!
