"I am writing this review after a year because I wanted to test it out and provide an honest review. We replaced our AC unit with a new one with the help of NathanD. He was extremely professional and offered us the best price compared to all the other companies we considered. The installation process only took half a day, and they also installed a Google Nest for us. Additionally, they assisted in fixing our broken circuit board in the garage. Overall, the workmanship was excellent, and NathanD answered all of our questions. He even followed up with us after 2 months to check on our satisfaction. We initially found him through Angie's List."

"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."

"Sent email through anigies list site, he called right away on a Sunday night - tried to help me fix my thermostat since it was only a year 1/2 old but we could not.  Did tell me he had a job in san diego that week.  since it was nothing major decided to wait since the reviews were good and he seemed honest.  finally was able to pick a good day, called letting me know he was on his way, showed up and first looked at my thermostat but it was broke, replaced with new one right away.  Explained how it worked also checked my filters and let me know where I could buy replacement ones at a good price.  Was quick, very friendly and professional.  Also does electrical work which I need so I will be calling in the future.

"We have a six year old AC system. A few days ago, on the first really hot day of the year, the system came on, provided cold air for about an hour, then quit. The first AC company that examined the system (the HVAC sub of a contractor who built a new room for us) said that the malfunction was due to a compressor gone bad and not the result of his having moved the condenser/compressor to the other side of our house. I called Iwai (who installed the system six years previously) for a second opinion. When the Iwai rep arrived, I explained to him that the fan at the top of the condenser/compressor was turning more slowly than normal, and the system just kind-of whines. The Iwai rep replied, "it sounds like a capacitor." Sure enough, within 10 minutes Brandon had the capacitor replaced and we had cold air. Given their quick response, diagnosis and repair, Iwai rates five stars with us."

Install Boiler questions, answered by experts

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.
