I have been using Alexs services for 2 years now and he does a fantastic job each time and his prices are the most competitive that Ive seen. Although he specializes in HVAC he is also a full service handyman and just fixed my garbage disposal. Highly recommend!

I recently had an issue with my HVAC condenser unit and reached out to multiple people for help. Three people came to fix it and didnt know the problem and charged me for diagnosis and asked me to replace the whole system. Alex came by looked at the system and changed the capacitor and everything went back to normal. I would definitely recommend him for HVAC services.

My water heater sprung a major leak, and despite my frantic attempts to reach a plumber, no one seemed to be picking up the phone. Then, like a guardian angel, Alex from Positive Plumbing answered my call. He made his way to my residence in Irvine, effectively preventing a potential flood situation. Remarkably, within a mere couple of hours, he not only put a stop to the leak but also managed to install a brand new water heater just in time for a family gathering.

Very positive experience with Alex. He didn't try to upsell me, just help me get the right solution (replacement water heater in my case) for the right price. I found him reasonable and responsive at every touch point. Would work with him again!

Alex, the owner of the business, is a capable guy, who is good at plumbing, heating, and air conditioning. In a recent visit, he was able to respond to my call, troubleshooting the issue, and walk away with a central air system running again. I appreciated his help especially during the hot summer season.

These guys really came through when needed. Alex responded really quickly and the communication was great. Sent a tech next morning which had a pleasure to meet his name Rodrigo. He was really helpful and explaining what was the issue. We had major leak issue because of our AC unit backflow and Rodrigo immediately told me what was wrong. Took care of it and the price was very reasonable for the work that was done. Thanks guys! saved us major damages in the future.

Finding a reliable HVAC company is not easy. Most will upsell their service and have you pay a service that you don't need it yet. Therefore, having known an HVAC company that actually know what they are doing and care about the problem is very rare and definitely is a keeper

I wanted to replace my old thermostats which were installed by the previous homeowners. From talking to the thermostat manufacturer, they were potentially tied to the security system which I was unable to uninstall. I was able to schedule Alex the same morning I spoke with him and he replaced the thermostats and even painted over the white patches the old units left. He waited for me to verify both thermostats work and answered all my questions. Thanks!

Great crew with excellent manners, on time, very clean work area. We used Alex and his team to replace air ducts and AC unit. They took great consideration of figuring out the amount of air flow in the house. The new AC unit is very quiet and the entire house is nice and cold. One of our room would get so little air before. Now it is nice and cold and it becomes our favorite room. We will be recommending Positive plumbing, heating and AC for AC and Heater work or maintenance. Thank you Alex, we are very happy with your work!

We use Alex's service to find and repair the leak in our sprinkler valve. The leak has caused us a big headache because the water bill went really high. Alex came on time and patiently explained the problem and how he's going to repair it. He's very humble and not like those other HVAC servicemen we used in the past where they are too cocky to explain the problem and the solution. Alex explained that our house sprinkler valve was old and it's the metal kind, not the PVC kind.

Over time the valve has become corroded and water seeps through causing the leak. Alex completes the repair within a few hours and he's definitely a life saver. His pricing is very competitive too. Thank you Alex for your help.

We used Alex to redo our AC drain pipe line since the previous contractor didn't do a good job in running the AC evap coil drain line. The previous contractor somehow combine the primary and the secondary drain line into one pipe which is not up to code. If there were clogging on the line somehow, it would've flooded our entire attic and it's definitely gonna be a disaster. Alex complete the job in no time and carefully explain how the primary and secondary drain line works. We are so grateful for Alex and we'd recommend Alex for anyone who needs to do things around the house the right way.

Weve used Positive Plumbing, Heating and Air for years now. Alex first installed a new AC compressor for our own home. Then my mom needed a new furnace, new ducts, etc so Alex did all that for her. Our rental units have needed maintenance, repair and replacement and weve always circled back to Positive. The value, workmanship, quality have always been very good. We always trust Alexs opinion and assessment and have always found him to be trustworthy and honest.

I have been using positive to service my AC for a few years and by now Alex and I have built a pretty trusting relationship. We've chatted about having young kids and taking care our family so I know he's a honest and hard working man. He is always responsive to my calls and always try to squeeze in time to at least come check out my problem. I would highly recommend him If you are looking for someone to be the go to guy for your household problems.

Our furnace stopped working Saturday morning. It's an older model. I called Positive Plumbling around 9 a.m. and he answered right away. Said someone would make it by the afternoon. The technician Alex called later that day and said he was on his way, and was right on time. In less than 30 minutes he diagnosed the problem. He explained the issue and answered my questions about different ways to fix it.
