Really happy we found this company. Our unit was leaking and I had gotten a quote from a different…read moreAC company quoted $1,200 and 1-2 hours of work. It felt high, so I got a few other opinions. Express quoted 600-800 but I really appreciated how genuine the owner was about the work scope, so we had them take a look. it ended up being 780 plus tax so 835, which is outside of the quote but not unreasonable. and obviously 50% cheaper than the first company. These people seem trustworthy and I would recommend them.

If my husband were still alive to advise me, I would have used a credit card. I would have asked…read morefor a written guarantee. I would have asked for pictures. But I was cold! And the company, Express Refrigeration Heating and Air, had great reviews! They offered to install a new part for my non-working gravity heater the next day at $3,700.00 and orally guaranteed it for 10 years with the promise of a fix for two years after the installation if anything went wrong. Shivering, I happily accepted the word of the technician. I am repenting in leisure. When the work was done, and the technician, Zack, told me that, if I wrote a good review on Yelp, they would pay me $25.00----in the form of a gift certificate to eBay, Amazon or an online company of my choice---I got a different idea about all those great reviews. The heater stopped working 6 months later. Fishing out the invoice, I saw there was no written proof of a guarantee. I took the tech at his word and hadn't checked. Again, I was cold! When, after many calls and an email, David dispatched a second tech from Express to assess the problem, he told me that water was dripping on the new part and that the water had ruined it. He charged me $80.00 for coming out, saying the failure was my fault. None of this was written down. The technician said he could get me another part for $3,700 or install a different heating system for $15,000. Either way, he said, the $80 would be applied. Now the nickel drops. The dawn breaks, and I hire an inspector to tell me whether there is a leaking pipe that I need to repair. The inspector told me there was nothing leaking on the new part, in fact there were no water pipes anywhere near the furnace, only gas pipes. He also said that the technician had installed a red bypass wire, a temporary fix at best. So this review. To alert others. 1. Ask for a written guarantee. 2. Use a credit card so you have recourse. 3. Read the invoice before you sign. 4. Ask to see a photo of the area. 5. Do the opposite of what I did. I'm still cold. P.S. to Cassandra, business mananger, who left a note after this review. This is not a mistake. My invoice number is 4623 and I saw Zack on November 4, 2024. I saw the second technician May 30, 2025. I am happy to talk to you. My phone number and private name is on the invoice. If you are unable to find the invoice, send me your email and I will quickly email it to you.

Pioneers Heating & Air came thru at the end today to handle the job. We are now cool and happy vibes. Life is back to normal. Israel was calm, curtioues, understanding and fast. We discussed the repair cost and optioned for extras at the end. The issue was that this old AC needed two components to continue its life span. I recommend this company hands down. Not feeling the heat anymore! Thank you guys.

Very disappointing and unprofessional experience -…read more I had a very disappointing experience with this company. I felt the technician significantly overcharged me. He did not clearly explain what the actual issue was or exactly what had been done to fix it. What concerned me even more was that I was not given a reasonable opportunity to verify that the repair had actually worked. I asked to let the AC run for some time so I could confirm that the issue was truly resolved, but the technician would not give me that time , not even 10 minutes. Instead, he aggressively demanded payment immediately, before I could even confirm that the repair had worked. He told me that if I did not make the payment on the spot, he would undo the work that had been done. Given his tone and the way he spoke to me, I felt intimidated and concerned that he might make the situation worse or damage something further. The lack of transparency was also concerning. He asked me to make the payment without sending an invoice. I specifically had to ask for an invoice. For a repair service, I would expect a clear explanation of the problem, the work performed, and the charges without having to repeatedly ask. The situation was especially uncomfortable because I was not physically at the property, since it is tenant occupied. I felt that the technician took advantage of the fact that I was not there in person and repeatedly pressured me to make the payment. I also asked to speak with someone from management, but I was not allowed to speak with anyone. Overall, this experience left me feeling extremely uncomfortable and taken advantage of. The aggressive payment demand, lack of clear explanation, refusal to give me time to verify the repair, threat to undo the work, and lack of transparency around the invoice were all very concerning. Based on my experience, I strongly recommend staying away from this company and considering other options.

I would absolutely call him again if anything comes up.

They took care of all the Burbank permitting, kept us updated, and delivered on schedule. The whole team -- estimator, project manager, installers, and even the president -- was friendly, responsive, and professional. The install was neatly done to blend in with house decor. Their price was reasonable and the value unbeatable. Solar adds about 4% to your home's value, so it justifies itself right away -- even if you sold your house next month! The Powerwall 3 works perfectly and gives us backup peace of mind during outages. Five stars. Highly recommended.

Alex sent me various quotes to repair and replace, and I ultimately decided to replace the whole unit. They were back out on Thursday morning, and worked tirelessly for 12 (!!) hours. This is after they realized that the ducting also had issues and needed replacing, which added an extra handful of hours. Alex and his colleague was professional, polite, respectful and extremely hardworking. They paid close attention to detail and left no issue unturned. I highly recommend these folks and would work with them again. Thank you Alex and team!
