"Nick Sinclair handled my project. He was really great. I had no clue that you had to have a permit in order to install a furnace or water heater. An inspector came out and told me that I would need a permit. They had to drive from Orange County to Riverside County in order to get the permits. These guys stopped everything, drove out there and took care of all the permits. They installed everything promptly and it was just the perfect job. Their prices are fantastic."

"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!!!

Install Boiler questions, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

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.

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.
