Best HVAC Installation Or Replacement in Anaheim CA

Our 50+ year old floor furnace (original, installed when house was built) stopped working after the summer. I was fortunate enough to find these guys after a Google search, my regular plumber does not do HVAC.
They came out and diagnosed the issues, (there were several) and repaired it working like new the same day, Frank even upgraded the ancient analog thermostat to a digital one, allowing us to set a temperature and not just switch on and off.
We were so pleased, when we decided to upgrade our home and install A/C, I called them first. Frank called back almost immediately, came out within an hour and provided a several options and a quote for both.
Frank suggested options and solutions to our questions and both he and Rick were back the next day to begin the installation process.
In spite of the rain and some miserable working conditions, they installed a state of the art compressor and cooling/heating system with two mini-splits, one in our master bedroom and another larger one in our living room. They are more than ample systems, required minimal disruption and will provide either heat or air conditioning, alleviating the sweltering nights of the summer we've had to endure for the last 20 years.
Both Rick and Frank were very friendly, chatted with us, answered questions, were professional and extremely careful with the installation and entire process. We couldn't have been happier with them and I'll be referring everyone I know to them and their services.

I had a problem with my garbage disposal we called la Mirada plumbing and the technician named Kevin came and reset the garbage disposal button. He was doing something with the pipe and when i asked what he was doing hes answer was im just checking it. After that, he charged us $105 for just 5 minutes. The 2nd day i turned it on and it wasn't working again, and water was coming out from the pipe that kevin was supposedly checking. so i called them to see if they can fix the problem that for sure Kevin had messed up. A lady answered me with a very nasty attitude and after i explained the problem to her she made it seem i was lying to her and i felt very offended. they offered me to send me another technician to check the problem but would charge me $180 on top of the $105 i had already had pay!!!! I DON'T RECOMMEND THIS COMPANY!! THEY ARE A BUNCH OF LIARS,THIEF'S AND CROOKS!!! THEY MADE ME PAY $105 FOR NOTHING MY GARBAGE DISPOSAL IS STILL BROKEN PLUS MY PIPE!!!!! WORST SERVICE EVER!!!

Updated review. Thank you Mr Moffett for the hot shower!!!! My water heater took a dump and I had to wash my hair in cold water super early in the morning.  Burrrrr. My husband called and while I was at work they came and installed a brand new one for half the price I thought it would be.

Truly unbelievably, you wouldn't think such a wonderful thing could happen right after a tragedy but this plumbing company made it happen(and in under an hour)!!!!!
Our sink was backing up!!! My only work uniform was in the washer. The dishwasher was running and water started pouring out everywhere, inside and out. My husband who works in the industry had exhausted all his resources. The owner Mike showed up and everything is better than new.

What a breath of fresh air from an HVAC company! Felipe came to our home and walked me through everything, listened carefully to all my concerns and never tried to sell me on anything. He brought Dennis in for a second pair of eyes on all the issues and concerns I brought up. Most of these issues were missed or dismissed by two previous HVAC specialists I brought in. They gave me a reasonable quote and I went ahead and scheduled the work. Luis and Alex came on time, were professional, respectful and communicative. They made sure I understood everything and the system is now perfectly dialed in. Nexgen are my go - to guys for sure.

NEVER, NEVER use Country Wide Plumbing Heating and Air.  We used them and they are total RIP OFF's.  They replaced a drain pipe under our bathroom sink and cleaned out the drain.  The also replaced a garbage disposal.  They charged us the exorbitant amount of $999 plus!!  I couldn't believe it.  I should have checked on Yelp before we called them.
