"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."

"Before, we only had a localized very old gas floor furnace. Total Home Environmental installed a centralized Heating/AC system in the attic and insulated the attic as well. They installed vents and ducts (first time for the house). They did a good job."

"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."

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!

Install Boiler questions, answered by experts

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
