Heating maintenance visit February 2026: Shantel and Guillermo provided a very through and timely assessment and service operation. This included accessing the furnace/air handler through a closet, working in a very tight attic space, and vacuuming blown-in insulation that had fallen through the access opening. They were very professional, efficient, and clearly explained their procedures and the condition of the equipment. Excellent work, plus they are just good guys. read more

Responsive and reasonably priced. They came out very fast on a hot summer day when the swamp cooler stopped working. I signed up for their monthly service fee so I can have their help at a moments notice for my rental! Nice helpful people from the phone call to the repair guys! read more

Two years ago last March I had Allianz install a new heating and air conditioning system in my home. Day before yesterday I started having problems with it. When I called them they informed me the parts were still under warranty, but not labor. I wasn't too worried about it thinking it was hopefully something small. The repairman took barely an hour and did have to replace a part. My bill was $441 for just labor. When I called their office to discuss this, this morning, the office girl informed me they charge per job on warranty work and this was their price. So this was a way for them getting around not charging me for parts under warranty. This is so wrong on every level. Please think twice before you hire this company... UPDATE- I just got a call from the general manager for Allianz Heating and Air. He not only apologized, but is going to credit my full bill back to me and give me a 10 year warranty on all parts and labor. Now that's good business practice. Thank you Josh, you not only restored my faith in the human race, you most definitely just won my business back. Changing my review to 5 stars... read more

Quick response time from initial call, showed up when promised( actually called and said he was running early and asked if he could come sooner!)Very professional and resolved issue at reasonable cost.Guillermo was a very polite, professional young man who explained what the problem was, what he was going to do to rectify and get us back in business---to a cool house!! I'm very impressed with the office personnel ( I spoke to Carmen), who took my original call and called me back within the hour to schedule someone at my residence.I believe in preventative maintenance and have signed up for Allianz program to come out before summer, and than again before winter to make sure everything is running efficiently. I would recommend this company and understand why they have been in business for awhile, ---they take care of the customer!! read more

My house is now warm & cozy! I am so appreciative of the excellent & professional service I received. Dan not only repaired my heater, but addressed all of my concerns & explained the safety mechanisms on the heater to me. I really appreciate the high level of customer service demonstrated & would enthusiastically recommend them to anyone in need. read more

After a very disappointing experience with another HVAC company in Redding, I was lucky and found Allianz. Everyone has been incredibly responsive and helpful. Dan N. showed up on time and on the day scheduled, reviewed my issues and made several recommendations and gave solid advice. installation went very smoothly and I've been really happy with the AC during the summer. We couldn't do a real test of the heating unit when the outside temp was 110+. When the weather cooled off, it was apparent that the heating unit wasn't at 100%. Dan N. came to the house, tested and fixed the heater same day. He explained what needed to be adjusted and took care of the minor problem. I am happy to recommend Allianz and Dan for exemplary service. read more

Once again, Allianz came through for us. After they installed our new heat pump last week (they did a great job and were very friendly and efficient!), we noticed some of the blown-in insulation from the attic was lodged in the registers. Two of the crew came out to our house this morning in the pouring rain to clean the registers for us. They were friendly and helpful, and they made us feel like we were their number one priority that morning, although their day had just started. Thank you, JC and Jose, for coming out on time and delivering excellent customer service! read more

Chris was so helpful. Gave me all information as to what needed to be fixed on AC. Monthly service very good.

I have a 4 year old unit that Allianz installed. Well it started having intermittent problems and was not cooling at those times. Allianz is so on it. They came out the first time about a month ago and did my regular tune up. Then it happened a second time this week. My unit would not cool below 84 degrees. Not only did Allianz get somebody out right away, but they sent 2 people saying it was unacceptable for us to be uncomfortable. They spent 3 hours tearing down, cleaning, and monitoring to find it was a bad capacitor. Thank you so much for your conscientiousness and sticking behind your product and your promise! read more

This company gets a one-star rating because it is required to write a review. Allianz is a greedy rip off the customer kind of business. Not an unusual posture because many companies have raised prices and rates during our current rate of inflation simply out of greed, and for the same reason, this company is one to be avoided as we will do from here on out. They charged $433 dollars to install a small, warranted part in our heating/air-conditioning unit. It took minutes to diagnose the problem and not much longer to install the part, less than an hour altogether. So, if you calculate wages at say $30 per hour you might have to include his time driving to the site, nevertheless after paying for the employee Allianz made a huge profit at around 80+ percent of the money collected for or a one-hour job. They charged $79 to diagnose the problem then charged $354 for the install, sort of overlapping the initial charge and the repair charge and total time less than an hour. Many businesses do not charge to provide an estimate. Also, when the employee got off the roof there was a loud crash on the roof, apparently, he didn't reattach part of the unit. Then to top it off the Allianz employee was unable to get an internet signal to complete his billing so asked for our password for wi-fi, and was annoyed we wouldn't give it to him. Apparently, he couldn't complete his work without internet access, how dumb is that. Yes, we are all reliant on the internet, but we don't give out a password to anyone. Then the employee used a pen that had f---k you written on it, real professional. Back to the overcharge, I get it the company has overhead so needs to charge over and above the hourly rate for an employee; however, their charge for what we had done was way beyond overhead and some profit, it was inflated and grossly overcharged and pure greed. How does the average customer with an average salary pay for an inflated cost such as we experienced to replace a warranted part on a relatively new heating/air conditioning unit. It is a kind of scam when you find you are grossly over charged for a minor repair taking less than an hour. Then to add insult to injury we were given some trashy plans we could sign up for to receive regular visits from Allianz and they would gladly take a monthly fee from our bank account. This was disgusting, they must think customers are stupid to fall for such a ploy for them to make more money. read more

3:00 am and I was smelling an odd smell coming from my heating unit. Since I'd just had the motor replaced a few days before, I was concerned. I called Allianz Heating and Air, and Wow! Dan and Alex came out, took everything apart to check the unit, and checked the air flow at each vent and through the filter. Happily, there was nothing going on with my unit - it must have been a neighbor's fireplace smoke I was smelling. But Dan and Alex had such a positive, customer friendly attitude, and understood the importance of having piece of mind. What a professional team, with amazing customer service. read more

Full install. Responsive, polite, and helpful with our heating and air installation needs. Completed the full installation in less than two days. Works well. Would recommend. read more

The people at this business are super nice and quick to respond all of the technicians. I've had at my house or top-notch. A song suggests I'll just align's heating and air for all your needs for service read more

Our heater went out in 30 degree weather and Dan came out within 24 hours to fix it. He was great and personable and fixed our issue within a couple hours. He went above and beyond and changed our filters as well, made sure all the vents were open, was very friendly with our dogs and my toddler. Thank you Dan for everything, we truly appreciate it! read more

They take good care of the HVAC unit they installed. They are definitely on our contacts app.

Great company! When our HVAC quit working last summer during the 112 degree period in June, Allianz was on it, getting a new unit installed. They even loaned us (free of charge) a portable swamp cooler hill we made the decision on which unit to install and waiting for it to arrive. I also installed a NEST thermostat which I wired incorrectly, causing the heat pump not to work. They came out and diagnosed the problem, fixed it, and charged me nothing. Rob was our technician. Thanks Rob! Allianz now has a loyal customer for life. Thanks. read more

Dan serviced our air conditioners. He was very thorough and conscientious, as always! Its refreshing in these times when someone enjoys their job, their co workers, their boss and their customers. Dan is one of those rare ones! Kylee called to let us know he was on his way, always outstanding customer service. Martin, owner of Allianz has an AMAZING crew who are reliable and credible in providing service. I've been a loyal customer for many years and highly recommend them without reservation. Lots of companies pitch a good story to win over customers, but when you have an emergency repair, its Allianz who takes it seriously and is there for you in a timely manner. Carole B., a long time, happy customer read more

I've used them twice. After yesterday I recommend everyone avoid them at all costs. $171 charge and my AC doesn't work and they refuse to fix it. Very rude officer person when I called to say the AC still didn't work after the service call. Technician wouldn't listen to me. Wouldn't help me. We requested a specific technician that our friend assured us was honest and reliable. They didn't send him. The first time I used them I had to replace the part they replaced 8 months later because according to the tech from the other company the wires were left long enough to get sucked into the fan and destroyed. Wouldn't have called them back if a friend hadn't referred us to his friend who works here. Wish I wouldn't have wasted my money on them. Out $171 and still have to find a reliable company to come fix my AC read more

By far the best company Northern California! From the owner to the technicians. My a/c decided to quit on me in this crazy heat and Allianz had me fixed and on a plan to keep it maintained in no time! Very fair prices. Thanks again Allianz. read more

I called in and spoke with Carrie, who sounded uninterested in my call and unwilling to get me to someone who could help assist me in my situation/question. The front line of a business is its customer service. This reflection of not caring to dive deeper and make sure I was helped properly goes to show that just because a place has good days and good work, we never know when someone will call and have a negative experience. I was kind and respectful to the person on the phone and will not do business with them due to unprofessional customer service. read more

Was looking into getting insulation added to our home as the utility Bill's seemed to keep getting higher every month and knowing our home was older there wasn't much in the attic anymore. I have used martin and his crew for years to service our unit and always had a great experience, but insulation is something I could do but really didnt want to. Martin came out and gave us an estimate to bring it up high enough to get the rebate through city of redding, seeing as me and my wife both work it was difficult to get it done with a time that worked for us. The 2 Technicians that came out to add the insulation, were cody and tanner. Both of them were very friendly, looked at the job prior to starting to make sure they didnt need anything before they got started. By the time they got there, to the time they left was only a couple hours, and they left no signs of them being there in the house. Our unit is kicking on a lot less than it did before, and seeing as I used to have r-11 in the attic, bringing it up to what u should have would have probably took me all day and having to run around to get the machine I would have rented back and hopefully I bought enough. Overall it was another very good experience from crew, I'd wait a little longer if these guys were busy to fix an issue for the fact they are always professional and never had to have them come back to fix anything twice. read more

Professional service and very competitive pricing...especially good when you are dealing with purchasing and servicing A/ C units that are thousands of $$$$... read more

Can't really rate them....they didn't show up. I was given a two hour window. Rushed home to meet them, sat around a few hours, and when I called they said 'your not in our system.' Urgh read more

These guys really took care of us fast! They tried to fix our a/c as least expensively as possible, when that didn't take they replaced our unit very quickly. Thank you Allianz for your speedy service, your customer service is top notch! read more

They save us from a super long weekend. My AC went out on a Thursday evening an my landlord assured me no one could help til Monday. I called Allianz first, and they had a tech out to my house an hour later. They were fast, clean, an helpful. Thank you! read more

Our central heating system started blowing only cold air on one of the coldest evenings of the year. Called Allianz the next morning at 8:00 am. A technician was at our house at 10:00 am. The repair was quickly accomplished and the cost was fair. The technician was very polite and pleasant. Highly recommend this company. read more

Of course, our HVAC decides to quit on a day that turns out to be 106 degrees. Three other companies could not get to us for at least four days. Allianz was not only able to come out the same day, Tom was able to diagnose the problem within minutes and correct the issue. No heavy handed service contract offers or other upgrade suggestions. He quickly fixed the problem in a very professional and courteous manner. Allianz will be our go to for HVAC service for now on. read more

Allianz responded to my review and asked for the details of my complaints. They subsequently agreed with my assessment of the situation and took remedial action with their employee. We agreed that the tech did not give me the correct information regarding my existing unit and that it was more of an oversight than a sales tactic. I am satisfied with their response and action and might use them in the future. They still need to work on the customer service communication part of their business though. read more

Our experience with Martin Graeff and the staff of Allianz was 100% positive. We had settled on another company but knew it was wise to get a second opinion. The huge number of positive reviews at Angie's List made us choose Allianz. We immediately learned a lot about HVAC units, but also the connections to the duct work. Everything Martin said checked out logically and when I researched his facts online. I actually expected a high price for this kind of knowledge and service, but we got a better deal than expected, and less than the other business quoted us. The installation was smooth and professional and was completed in a timely manner. I'm the sort who chooses the best professional over the best deal, but in this case I got both. read more

It was cold last night. I don't do great in the cold. My chubby poodle does not like the cold. We got tired of our poodle sitting in front of the space heater and taking up all of the heat, so we called Allianz. First off, the young lady who answered the phone was polite, patient and asked all of the right questions. At first there were some scheduling conflicts, but she said that she could get someone out the same day. VERY EASY to talk to! Later on, the young lady called and let me know that the technician , Robb, would be out shortly. I'm only good at a few things in life and HVAC is definitely not one of them. I know less than nothing about the subject. Robb could have told me that Larry the Magic HVAC Goblin had turned off the mystical AC valve and I would not have known the difference. Long story short, there was one tiny little adjustment that needed to be done, and boom Robb was out the door to save someone else's day. Robb the technician was EXTREMELY personable, polite and professional. He took the time to explain everything in simple terms. While I didn't have the most technical issue, Robb didn't talk down or make me feel like a moron since it was such minor issue. Theses are the HVAC people you are looking for. read more

Just wanted to thank the guys at Allianz for their awesome customer service! This was a great experience from all the e-mail/phone reminders to the guys that came out and did the job. I can defiantly recommend these guys for your next job. read more

These people are very rude we tried to pay them for the job when their tech finished he would not take money saying they would bill us and the next few days the Allianz office was harassing us about their payment! we never got an invoice or anything other than a bunch of harassing phone calls. This was only a 2 day old invoice! These people are very rude and do not listen very well read more
