 Trustindex verifies that the original source of the review is Google. During a heat wave here in San Diego we ran into hot air blowing into our house… Like most HVAC companies they were booked out a week plus but Chris and his professionalism was amazing… He was texting and providing guidance which included pictures recommendations troubleshooting, and it helped us fix our problem. Same day… Unbelievable and what a great experience we had with this company.

He has been helping my mom and myself for multiple times.  He is someone we can trust rather than other sale person which only wanted you to buy tens thousands dollars new system.  Reliable Standard Heating & Air sincerely want what's best for you and your family.  I trustily appreciated them.

 Trustindex verifies that the original source of the review is Google. My very old AC finally stopped working.  Two very well known and very large companies came out and gave me quotes to replace everything - $24000 for one and $46000 for another - because that’s what they said was necessary.   I decided I needed a 3rd opinion.  Called Reliable and was immediately told “sounds like you had a salesman come out.”  Alex came out a couple days later and within about 2 hours my very old machine was up and running again.  All of those “major issues” the first 2 companies identified were no longer  an issue.  My furnace was suddenly perfectly fine and my ductwork was adequate. Honesty in a trade professional is the most important thing to me.  Alex could have gone along with the other two companies and probably came in well under them and sold me a whole new system. Instead, for a tiny fraction of the cost of a new system my current one is running fine and will get me through this season at least. Knowing that you are not being taken advantage of and having a company that responds quickly is invaluable.

 Trustindex verifies that the original source of the review is Google. AC unit was freezing up after 4-6 hours of confuse use. Spoke with Chris and he was super knowledgeable and was able to get someone out the fix the issues the next day. Needed a deep clean on the indoor evaporator coil and to replace a failing TXV valve. Got a call when the work was finished along with videos and pictures since I wasn’t home. Great communication, great service, great people.

 Trustindex verifies that the original source of the review is Google. We had a bad experience with a different HVAC company (basically they started the job, left everything "undone" so we needed help with knowing our options on a home that was for sale. Chris was amazing by telling us what needed to be done. We ended up not doing anything as we figured the new buyer would have the work done themselves. Meanwhile, the a/c unit was taken apart by previous guy  (Raphael Cota, fyi buyer be super aware)... but Chis took the time from his over busy schedule and put it back together again at a very low cost! Chris was very on top with communication, with giving straight facts and overall very pleasant to work with. I 1000% recommend him for any HVAC job. He's amazing and so on top of everything. His company name, Reliable is perfect, because they truly are! 5+ star service all the way! ☆☆☆☆☆ Thanks Chris ... I will forever recommend you!

 Trustindex verifies that the original source of the review is Google. Family owned and operated. I've used Reliable heating, cooling, and air twice,  and each time, was an amazing experience. I called because the A/C stopped working at my son's house, and we needed it repaired ASAP. Spoke with Alex (owner), and explained that there was a clicking noise coming from the compressor. My son and I watched as Alex diagnosed the problem as the capacitor, and contactor. Luckily, he had the parts to fix our Air Conditioning problem on the spot. The unit turned on, and when tested, it wasn't blowing very cold air (we wondered why the house was not cooling very well even when A/C was running). Alex told us the unit was very low on refrigerant, and added it. Alex was honest and extremely professional with this visit and when I used his company to repair my older A/C at my house a few years ago. My son (26) had experienced technicians that weren't honest in the past, and to witness an honest guy not try to upsell anything was valuable. Here's what I know: * Reliable heating, cooling & air is the real deal * Honest about the problem and explain everything to help make informed decision *All questions answered patiently *Professional and friendly *They give  a military discount They Promise to You to Perform the Correct Air Conditioning Repair at an Honest Price - they do just that. Thank you again, Alex.

 Trustindex verifies that the original source of the review is Google. Highly Recommend! Very Happy with the Excellent experience we had with Reliable Standard Heating and Air. We worked with Chris, he was very knowledgeable and responsive. He provided by far the best price and value from 5 bids for our Furnace replacement and Heat Pump addition. Chris really went the extra mile with providing detailed responses our questions with pros and cons different HVAC system options available while always pointing out opportunities for cost reductions. I have since referred them to friends repairing, replacing or upgrading their systems and everyone has come away a very happy customer.
