"I had 4 estimates.  The first vendor said he would be unable to test for leaks and said he would install new system and gave us a one line estimate.

 The second vendor said he could fill with freeon for $800 with no warranty or put in new system for $15k with no itemization,  He only attached a pressure gauge to outside line and was going to charge my very elderly Mom $105.  When I called owner and said that no diagnosis was made and this is ludicrous, he dropped the charge.

 The third vendor spent well over an hour explaining why his company is great and then said the charge would be approximately $9,500.

the fourth vendor was Mick Sinclair and what a completely different experience. I first called and spoke to Nick, his son.  I told him I did not know what to do.  Although both Nick and his Dad were booked solid he said he would get back to me.  Mick called and scheduled an appointment. He measured the pressure and tried to fix the valve. He then actually removed the outer shell of the condensor and noted that the motor was not working at all.  He tried to fix the motor and added a booster to no avail.  He refused to charge anything for the diagnostic and attempted repair - nothing!

Note, that not one of the other three vendors checked the motor.

Mick then said he would email a quote which he did in a very timely manner. His wife sent the email and I spoke to her and she was as nice as Mick and their son, Nick.

Mick spent 1-1/2 days performing the complete installation, including sealing asbestos and many other things.

There are literally no words to explain the excellent service we received from Mick. He is also very kind.

My 92 year old Mom and I are grateful for you.  You are truly a professional.

Thank you!

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"That was fine. They were good. I think it was before summer or whatnot. I just wanted to make sure that everything was in working order because I had my AC go out a couple of times, but they were easy fixes, but I just wanted to have a preliminary check on it before we got into summer. There was an additional price for the part that they needed. When they got out here they were efficient and fixed it. I know he had to kind of jury-rig part of it but it wasn't something that uncommon I guess this time, because of the type of system that I have. But he made it work. He figured out how to install certain parts so it would work, and it still does. I don't think I have any improvements."

Thermostat screen went blank-furnace and A/C wouldn't come on

Chris arrived within 1 hour of my call and checked the furnace first. He found a blown fuse and no power to low voltage wires inside the unit. He then checked the thermostat and found it was no longer working. Chris replaced the fuses and the thermostat with a similar unit and tested the entire system. He then checked my A/C unit for Freon levels and found and repaired a wire that had come loose.

Chris was very pleasant to work with and explained what he was checking and why as he went along. He explained how the new thermostat worked and provided me with both the installation and operating manuals. Great service!

"On Thu, Aug 4, 2016, my 13-year-old Rheem, builder's grade HVAC system stopped working. Since I had experienced good service with Home Comfort (formerly American Comfort) over the last several years (Home Comfort did not sell me my old system; I purchased it from an independent contractor), I called to schedule an appointment regarding different options Home Comfort could offer me. On Sat, Aug 6, I selected an upgraded, high-end, Lennox resort-grade system and emphasized that I wanted an auto-switch thermostat that I had been used to on my previous system (automatically switches between AC and heat as needed). The installation was performed Mon, Aug 8, and took approximately 8.5 hours. When I asked the installers if I had an auto thermostat for the new system, they said yes. They removed the old system, insulated the walls of the furnace closet, and installed and rewired the new system. It all looked wonderful, quickly passed city inspection, worked very quietly, and cooled efficiently. Three months later, on Fri, Nov 18, when temperatures began dropping at night--and the day before I was leaving for a 2-week vacation out of state--I realized that I had a manual thermostat and had to adjust the thermostat to heat. Unfortunately, I also discovered that the heat wasn't working. I double-checked the thermostat and the Lennox manuals to ensure I hadn't overlooked any steps. On Sat, Nov 19, I called for service, but due to short-handed availability of technicians (Customer Service (CS) representative said a couple of technicians had called in sick), they couldn't send anyone until Monday. I was concerned because I had family members (adult and child) in the house while I was gone on vacation. Since I would be on vacation on the day of service, I arranged for someone to be at the house during the window of time provided by the CS representative (2-4 pm because CS rep told me that the technician did not have a heavy schedule that afternoon). On Monday afternoon, the person waiting at my home texted me at 4:15 pm and said no technician had showed up, and I asked that person to call the CS phone number I texted. He did and informed me that the new ETA was 5 pm and that the CS rep told him that the standard service window of time was 1 pm-5 pm. Five pm came and went, and the new ETA from CS was 6 pm. The person canceled the service because he had to leave. My adult family member at home told me when I called to wait to schedule service until I came back from vacation because it was too stressful and unreliable to schedule service. While on vacation, I purchased an auto thermostat at Costco that was the same brand (Honeywell) as the one that Home Comfort installed (I didn't want to fight the issue about an auto thermostat and just wanted it done). My family members used the fireplace and blankets to keep warm at night. I called CS several days (Wednesday) before I returned from vacation (Saturday) to ensure a technician would come first thing Monday morning, Dec 5, and to let them know that I also wanted the technician to replace the thermostat with the one I purchased. The CS rep provided a window of time between 8-10 am. On Dec 5, about 9:30 am, a CS rep called me to let me know that the technician would be there closer to 10 am. He showed up about 10:30 am. It took him about two hours to check everything, rewire the system (it had been mis-wired), and test everything (both heat and cooling). He also had to call the Honeywell CS (15 minutes on Hold) to walk him through the system programming because the technician said it didn't go according to instructions in the manual. Happily, Home Comfort did not charge me a dime for service because it was included under the warranty. The cost in this review was the amount I paid in August for the system."

"Not only did the technician find what was wrong, he told me that the unit was in really good shape (after he got it running) and that it was good to go for many more years.  That's honesty for ya!  I know that IWAI is a little far from the westside of LA but I called Craig anyway because of the great job he did for another one of my clients.   The tech got out there within 48 hours and made some minor repairs to a unit that I was told would possibly need replacing.  My clients were thrilled at the low cost of the inspection and that it only needed a couple of parts to get it running like new.  They ended up buying the condo and are extremely happy.  But wait, there's more!  
(Second Job) I met Craig in January of 2015 when he came out to look at a heating problem in one of my client's apartment complexes in Beverly Hills.  This was an old building (1947) that had 3 gravity furnaces underneath the property.  All 3 were original and failing.  I got three bids to have them removed and replaced with new units.  One bid was just over $18,000, the other just over $16,000. Mind you, this was to remove three gravity furnaces, replace them with new gas furnaces, including some duct work, as well as do a complete new installation in the attic of the top floor unit.  IWAI's price came in approx. $8,000 cheaper than the highest bid!!! $8,000!!!!  I was skeptical at first.  I mean who wouldn't be?  An $8,000 difference?  But I discussed it with my client and we went with IWAI Heating and Cooling.  Not only did Craig do what he said he was going to do, but he started on the day he promised, and he finished on time as well!!!  The tenants had only nice things to say about he and his crew and no one was inconvenienced but for a couple of hours when an air return had to be installed in one of the lower units.  The job couldn't have gone any better and the price was outrageously inexpensive for the work that was performed.  My client was thrilled and so were her tenants, especially now that they had heat.  Thanks to Craig and his crew for taking care of this job with the upmost professionalism.  If you need anything regarding HVAC, call IWAI heating and cooling.  Have them come out and give you a quote; you'll be glad you did!!!
