Reviews of local pros in Antelope, California

Alex and his company are truly what good customer service is all about. His price was fair and he's a very good listener. Thanks Alex for your professionalism on the job.

I used Alex for many years, he is quick to respond and very honest. Prices are very reasonable as well. Highly recommend High Performance Heating and Air for all of your heating and air conditioning needs.

High Performance Heating and Air were great to work with. Showed up exactly when they said they would and had our A/C back up and running in no time. Highly Recommend!

High Performance Heating and Air is the premier choice for superior HVAC system installation. Alex and his team expertly installed our new system, demonstrating professionalism and technical expertise. Alex's fair pricing and skilled workmanship are highly commendable. We wholeheartedly recommend their services to our family and friends.

EVERY TIME that my ac has crapped out, Alex and his team has immediately responded. ASAP ! His honesty and pricing is a gift he shares. My daughter also uses Alex and as a father, I am completely comfortable with the work done at her hause. Alex stood out by contradicting other ac companies that were trying to oversell me. with Alex….. you only get what you need !

I recently had my air conditioning unit serviced by High Performance Heating and Air, and I can't say enough good things about them! From the moment I called, their customer service was top-notch. The technician arrived on time, was super friendly, and really knew his stuff. He took the time to explain everything he was doing and answered all my questions. My AC is running like new now, and I couldn't be happier! Highly recommend High Performance Heating and Air for anyone needing AC service. They truly go above and beyond!

I sold my van to Alex and the experience was very professional. He was very honest and detailed oriented. After negotiations I left feeling very good about the transaction. If I lived in the area and needed his services I would be very confident to do business with him. Alex is trustworthy and operates with integrity.

I was referred to High Performance by a neighbor and I could not be happier with my experience. The customer service I received was top notch. I loved the clear communication I received throughout the process and they made getting a new HVAC system as stress free as possible. Alex had some great suggestions for us. We originally wanted to upsize a duct in our living room but Alex suggested upsizing the duct in our bedroom instead. I’m so glad he made this suggestion. With the new system being far more efficient we would have been freezing in the living room. His suggestion made it so that our house as a whole is now more comfortable. Lily handled all of the paperwork and coordinated the scheduling of the inspections and SMUD rebates. She was amazing and I truly appreciate how easy she made it for us. I highly recommend this company for any HVAC work that you may need. I’m so happy to have found a trustworthy, hardworking, and professional company to use in the future.

I've worked with Alex for over 15 years across multiple rental properties, and he remains my go-to HVAC professional for a reason. He is incredibly reliable, always shows up on time, and responds promptly—even in urgent situations.

What sets Alex apart is how thoroughly he explains every job, down to the smallest detail. Unlike many other companies, he never pushes unnecessary work or tries to upsell. Instead, he consistently prioritizes the customer's best interest, delivering honest, high-quality service at a fair price.

Alex strikes a rare balance between economy and excellence, and I trust him completely. If you're looking for someone dependable, transparent, and skilled, I highly recommend him.

Alex from High performance heating and air was awesome. He was very responsive and kept us informed throughout the repair. Not only were his prices reasonable, he also researched where to obtain the necessary part from multiple suppliers and provided us with a couple of options for our repair. We will definitely be going with Alex and high performance heating and air the next time we need HVAC service!

Alex is the best! He is honest, does quality work and you can trust his analysis of your problem. He won’t try to sell you something you don’t need. They are not overpriced like some of these companies you hear in the radio. I highly recommend them. I will never use anyone else as long as they are in business.

Over 5 years ago we called Alex for the first time and since then he has been our go to hvac technician. He earned our trust and respect with honesty, integrity and quality performance. Recently he did a whole system replacement and everything went smoothly and painlessly. He listens to our needs/ideas and is open to give us advice even if it’s not in his best business interests. Very reasonable prices. It’s nice to have someone who cares.

Alex is the guy you want when you're in a tough spot. He came out immediately in an emergency, replaced my furnace, and had everything up and running in no time. He’s fast, professional, and incredibly honest- he explains everything clearly, never overcharges, and makes sure the job is done right the first time. I’ve used his services for years, and every time, he proves to be reliable and efficient. He doesn’t cut corners, treats every job with care, and genuinely looks out for his clients. If you need someone who truly knows what they’re doing and won’t waste your time, Alex is the one to call.

Alex and his team (High Performance Heating and Air) are honest, respectable and professional. Excellent communication and fast response time. I have used their services multiple times (this is my 3rd time) and would recommend them to any friend or family. Also amazing fair prices. If you want to use those "BB" guys and pay more I guess that's up to you. 6 out of 5 stars!

Alex with High Performance Heating and Air is the best! He was so impressive coming out on a holiday weekend while my family was suffering without air conditioning during a heat wave! He was so fair with parts and repair cost, and is truly an angel for the way he does business. Thank you, Alex, and I highly recommend High Performance Heating and Air for anybody in need of relief from heating and or air conditioning woes!!! Review posted on behalf of David Stearns

I have been using High Performance Heating and Air for all our HVAC servicing and installation for over 10 years! They are reliable, professional, and often less expensive than competitors. They have been and continue to be an absolute pleasure to work with.

If you're looking for reliable HVAC service, I highly recommend Alex at High-Performance Heating and Air! He’s been servicing our LOGMC church’s air conditioners for years, and we couldn't be happier with his work. Alex is quick, professional, and extremely knowledgeable. He takes the time to explain everything throughout the repair and handles every detail with care. Whenever any part needs replacing, he ensures we get it at a reasonable price. We've had several emergency situations, and Alex has always been super responsive, even coming in the evening to make sure our air conditioning is up and running for Sunday services. We’re incredibly grateful for his dedication and exceptional service. If you need someone you can trust to get the job done right, Alex is the person to call!

Alex and his team are phenomenal. Always professional, punctual, and communicative. They charge a fair price and do quality work. I always appreciate that when they come out to do a service call or diagnostics, I get an explanation of what the problem is and how it should be fixed (all in a way that makes sense). I’ve never felt like I was getting charged for work that wasn’t necessary and I highly value that. They will continue to have my business until I move so far away that I am forced to go with another HVAC company, hopefully not for a long long time.

High Performance Heating and Air is the absolute best! Alex is amazing at what he does. He is honest, trustworthy and very responsive. Helped get my AC back up and running very quickly at a fraction of what I was expecting. And made an extra stop on a Sunday to help us out! Definitely earned our family as lifelong customers. Thank you!

Reliable professional company! We replaced our whole HAVAC system several years ago including the complete ductwork. They were the best then and continue to be as they perform our biannually maintenance. Thank you Alex for being the best!!!

Excellent customer service! Alex went above and beyond expectations. He went out of his way to help my family during the hottest days of the summer when he could have easily pushed our A/C issue back to a more convenient time for him. It is easy to see Alex knows what he is doing as he had parts picked up and the repair complete the same day. He was referred to us by a friend (thank you!) and we will do the same if anyone asks about who they can trust with an HVAC issue!
