"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"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."

"West Tech Mechanical Services (Joe Gonsalez) did an excellent job. This is the best investment that I have ever made for our quality of life in our home. Joe's attention to detail is evident in the care and consideration that he put into the duct work in the installation process. He thoroughly explained to me the importance of the duct work: location and size of the ducts to maximize the efficiency of the system that he was installing. Our home is an old home, and I really appreciate the care that he took in the installation process. I obtained 3 quotes for this job and West Tech Mechanical was in the middle. All the persons that came to our house were nice people. However, Joe's obvious attention to detail and how he explained the job is what convinced me that he and his company were the right people for the job. For a home owner that is considering the installation of a central air and heat system in their home or, any work for that matter on an existing heat and air system, I highly recommend this company as one that should be considered."

"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!

"The access panel on the unit was slightly bent as was the unit. Instead of repairing the installers taped it up with duct tape. The panel fell off and I had to call for another service man to come out and correct the problem. The second technician did a much better job."

"FIRST: This company is TERRIBLE at communications once they've made the sale. Craig the owner will take his time getting back to you, IF he ever does. 

I had a very undersized AC/heating unit on my house and my electric bill was enormous. I decided to have it all redone and after reading a number of great reviews on Angie's List, settled on using Craig at Iwai Cooling & Heating. I ended up getting the top of the line unit, 2 actually for 2 zones, costing a little over $27k. 

The installation went pretty well, except for one installer who had a really bad attitude. They installed the gas line in the wrong place on the outside of my house, even though my kitchen was completely gutted (for a remodel) and they should have put it on the inside of the open wall. When I asked them about it, the worker got really irate and snapped at me that I should have told him sooner. My response was that I shouldn't have had to tell him at all! Why would someone want an exposed gas pipe on the outside of their house when it could be hidden on the inside of the wall???

They also didn't plan some things very well and didn't seem to know the L.A. building code on some things. They didn't seem to know that the AC platform needs to  be within 20' of an attic entrance, which threw off our kitchen remodel design. I had to forego skylights in my kitchen because they had to put the unit over my kitchen in the attic, instead of over my bedroom. They also didn't plan well where to put the AC unit on my roof and there was a delay while they had to build a special platform for it to sit on. That all should have been pre-planned while we were waiting for the units on order. 

During my kitchen remodel, one of my expensive touch-screen thermostats was smashed by a worker. I contacted Craig to get me a new one on Aug 4. It's now Aug 15th, 107º outside and we still don't have it. I texted Craig several times for an ETA, sometimes he responds, sometimes he doesn't. Finally yesterday I texted him and he responded that it was in. It was 105º outside and I offered to drive to his office to pick up the thermostat. He told me it was in Irwindale. I said that's fine, it's too hot to ilve without it any longer. Then he tells me to just go buy a cheap one at Home Depot. I'm starting to think that the thermostat isn't in after all. I tell him I still have my old thermostat and that I tried hooking it up but couldn't get it to work. He gives me instructions on what color wires go where. I start hooking it up...the wires spark. THEN he texts me to turn off the electricity before doing it (Mind you, there's 15-20 minutes between each of his texts). I get it hooked up like he says, turn it on and the unit sparks and blows a fuse in the attic. I tell him the wiring must be wrong at the AC unit. He says no. 

Now I'm sitting in the attic waiting for him to tell me how to get this fixed and he stops responding all together. I text him the next day saying I'm going to write bad reviews for him leaving me stranded. He texts me right back that he didn't see my messages. Baloney.

Then he says it's hard to see (in the photo I sent him) where the wires are going. I reply he should know where they're going, his company installed it!  He then says he's going to have the technician that installed it contact me. Then no further word that night. The next morning I text him that I never heard from the technician. He then writes back, and I assume he thinks he's texting his technician and not me, "Make sure you call this guy he's all p***** off. Not sure how u wired the t stat. he wants you to walk through so for write (sic) now he can put a cheap one..."

Remember, it was HIS idea to put on a cheap thermostat!

I write him back and say I'm sure he meant that for his technician, and how professional it is to badmouth his customers to his workers. I said I guess he thinks I shouldn't be p***** at having to sit in the heat again today. He writes back: "Sorry, just trying to get you taken care of."

His tech does text me, but tells me that my AC unit won't work with a cheap thermostat....directly in conflict to what the owner, Craig, tells me. He goes on to say that if I mess with the unit they won't be responsible for it. I tell him that it was the owner that told me to mess with the wires and what order to put them in so HE'LL be responsible if anything goes wrong! 

I actually think I can hook up a cheap thermostat, I don't think these people know what they're talking about. The manual from American Standard shows a hookup with the 6 colored wires I have instead of just the three that they hooked up. I think they just don't have the new thermostat...he just never expected me to say I'll come pick it up. 

They still haven't finished installing all my grills and I still need to have some sort of testing done, so I still have to deal with these people. That is, if they ever answer their calls. I see other people have complained about their bad communication as well.

UPDATE: It's been two months since I wrote my review and I'm still waiting for them to finish this job and final my permit. I have texted Craig 6 or more times asking him what's going on with making the appointment for the HERS testing. When he responds he says he'll call the company and then I hear nothing. I texted him again the other day and he wrote back he was going to try a different company...again no response.

Install Boiler questions, answered by experts

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
