April '21: Big Bear replaced my air handler motor part# 60L21 ($209 at Amazon) and 75 minutes of labor...cost $872 (plus $89 diagnostic fee).

Have used these guys for a decade and was extremely happy with them, however Big Bear has changed ownership within the last year or two.

We contacted Big Bear upon recommendation from a friend and were not disappointed. We subscribed to their annual service plan to maintain our two HVAC systems in the house we purchased within the last few years.

It was our first major checkup and they diagnosed two failing capacitors in our heating system and showed me (on the multimeter) why they were failing.

They also re-taped the wiring/lines from our outdoor A/C condenser units that had been damaged by rats at no additional charge.

Great service, friendly staff! Thanks, Claudio!

Still the best and trustworthy A/C and Heating contractor. Serviceman Brien is great at what he does and didn't take long to find the problem. Brian like EZ (Ezekiel) were a great find for Big Bear and both are very professional and knowledgeable. I will recommend them to anyone needing service or repair. THANKS

I called for someone to come out to help on my AC after reading the reviews and recommendations from my neighbors. The lady on the phone was so rude. She treated me like I'm stupid and didn't listen to me when I described the problem. She ended up calling back to ask for more details because she's failed to listen the first time. All she was worried about communicating to me was there would be a $89 charge on diagnosis which is fine with me. She didn't give me a timeline either. Said I have to wait all day because I'm on a waiting list. I normally get a time frame like

Great service once again by Big Bear! Martin was the technician that came out to our house to check out our A/C and heat for the upcoming season. He was prompt, courteous and thorough. We've been with Big Bear for almost 10 years and they have provided consistent and friendly service each time. We highly recommend Big Bear for A/C and Heating needs!

Well I called them for a 2nd opinion on a HVAC replacement after reading all these glowing reviews. The woman on the phone was brusque and told me they would charge $89 for the visit which could be applied to any purchase. I was ok with that but just her attitude and tone of voice put me off from dealing with this company.

Called this morning to get thermostats installed and to troubleshoot why there was no power to the head unit down stairs. Called a handy man who came and looked at the unit and wanted to charge me $600 (400 to troubleshoot and 200 to install). Couldn't justify paying that much and handy man got upset so he left. Called big bear and they were very courteous on the phone and sent Brian within the hour. Brian looked at the unit and it was a $0.50 cent fuse that had blown out. He replaced it and installed my units for less than 1/3 the price the handy man was charging. Very please with the quick

This is the best AC company I have ever dealt with. I have been using them for the past 5 years. They have replaced both of my units. I have had other companies come out and give me quotes but I always choose to go with Bear. They aren't the cheapest but they definitely save me money. I have had several issues with certain rooms being hot all the time while other parts of the house are ice cold. Bear looked at the situation and explained exactly how to fix it and gave a quote. He did the work and guess what ..... now all the rooms are the same temperature. He is awesome. HIGHLY recommend

There was a hot time at the ol' house last night! Our AC died. In AUGUST. In TEXAS. And it's HUMID. We managed to swim to the phone for help just after 9am and were placed on stand-by. With confident reassurance Tasha said someone would come see about us today at some point. So we opened the windows and huddled in front of the fan with a large bowl of lemons. This event clearly called for lemonade. Enough to fill the Jethro-pitcher.

The phone rang before we sliced the lemons! Big Bear Bryan arrived by 11am, replaced a part, waited for the inside temp to drop, and was done

Saved me $4800!!!
Our 11 yr old unit went out. 1st AC guy came and after many tries to diagnose the problem said it was a $5k repair. So naturally I said I need a 2nd opinion. Well next guy said we need a new unit: another $5000 bid. So after some research we found Big Bear: wow turns out we just needed a new capacitor a $186 part. It went out and caused the compressor to overheat.... The compressor is fine. He was here less than 45 min and did the repair. Wow!! After having it explained to me it seemed pretty basic. When the capacitor goes out the compressor has to overcompensate and

I have had several issues with our AC in our previous and in our new home too, I guess living in Texas you are not immune to AC problems. Diehl has always been on time, super fast and has fixed all the issues on the first try. He is also very knowledgeable about warranties and recalls and that saved us $500 one time that our AC died. He knew about a recall and got the part from the manufacturer for free. I could go on and on about his stellar work, but just know you are in the best hands. He is very hard working and honest. Absolutely recommend!

I can do nothing but rave about the great service from Big Bear Air and Heating I received today. My fifteen year old system stopped working yesterday in this 99 degree heat. I sent an email request late last night and received a call from them at 7:30 this morning to put me on the "standby" schedule. At around 9:00 I received a call asking if I was available in 10 minutes and I was thrilled. Diel arrived shortly afterwards and was fantastic. He checked the system and explained everything to me. He was able to get it up and running in 20 minutes and I am a happy camper. I can&apos

If you're looking for good service, competitive prices, and knowledgable techs, this is the company for you! Our upstairs unit stopped cooling on Thursday night, called Friday afternoon and they were at our home Saturday morning. The company who put our units in (when it was built in 2006) and have done our yearly maintenance couldn't come out till the next week. Thankfully it was an easy and fairly inexpensive fix. We will definitely be switching to them for our maintenance and care! Thanks Big Bear!

Don't know where to start ... Diel Rojas answered my plea for help two days ago when I realized our AC was not working at 7pm. I had heard good things about this contractor and trusted my instincts and called and sent an email asking for urgent help. He responded within 5 minutes and was at my house within 40 minutes. Diagnosed the issue which could not be fixed until the next day. He helped me get a floor fan set up for my husband who is bedridden. The next day a new compressor was installed and cool air blowing in no time. I am so very grateful to him for his compassion and dedication

I called other places and the fastest they could come out was 3+ days - but Diel with Big Bear came out three hours after I called, and the problem with our AC was fixed in about 15 minutes. I'll never use another AC company again!
