"The guy who came was really good. However, I was surprised by the cost of the toilet.  A normal toilet will cost about $250-$300 and I paid $600.  I thought they were expensive, but was later told the "Toro" was a high-end toilet..  The guy who came out was really nice and very good at the installation."
Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer.  This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

"This is a family owned small business. They are friendly, professional, punctual, and really know their stuff. All at a very fair price. My AC had been getting worse every year until last year. HVAC Utor came out and fixed it. It ran better than ever before. This year it was just blowing air so I called again. Same great service as last year. Rachel kept me informed so I knew when they would be here. The problem turned out to be the new thermostat I had installed a couple of months ago. Diego had it figured out and fixed in 15 minutes. I can't say enough good about this company and the people who run it. They're the best!"

"The technicians that came to install our HVAC system were super friendly and accommodating to my many requests about locations of the furnace, vent pipes, the condenser wiring, piping, and the condenser itself. When I asked for a 90 degree boot feeding two registers so the piping could stay high, a technician made a run to a store and found them. I want to give a shout out to Danny Aguilar who installed the furnace with Edgar and Victor. Grant Duran with Jose and Richard did an amazing job installing the vent pipes. Finally Adolph Garcia with Gabriel and later several other technicians I previously mentioned all worked to install the AC system (condenser and its plumbing + electrical). They worked late into the day to complete the job. I was very demanding in where I wanted things installed and requested changes on a regular basis but in all cases I was accommodated."

"During the extensive inspection and water heater flush, the technician (Kieth) identified a vast number of issues with my water heater that we were not aware of. It would be easy to think that he was trying to sell me extra services, except that he took to time to clearly explain all of the things as they were, and how they should be, and clearly pointed out all of the areas that our water heater was falling behind in. Many of the things he showed us explained some of the challenges that we were experiencing which caused us to order the service in the first place. Despite our 20 year old water heater still functioning, it was clear that we needed to replace it before something catastrophic happened.
We were able to go over our options and schedule the install of the new water heater the very next day. The new water heater with all the services, extended warranties and parts, cost us around $1,200. Although this was an unexpected cost, the performance and function of our new water heater is well worth it. Kieth was very professional and very friendly. He even installed our new garbage disposal during this same service. Benjamin Franklin might be pricey (I have no good frame of reference), but the service from Kieth was outstanding.

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"

"NATS responded the same day that I called them and picked the computer up at my home. Several days later, Mike called and stated the service to be performed, ensuring the size of the replacement hard disk drive, and provided the approximate cost. Within a week (Memorial Day weekend was during this period), Mike delivered the computer back to my house. I was pleased that Mike had not only reloaded Windows 7 (I had to input my own product code), but he had also spent the time to download and install upgrades to Windows 7."

Install Boiler FAQs, answered by experts

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.

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.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Costs depend on issue severity, parts needed, and labor rates.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.
