We started Better Water Heaters to provide fair pricing and quality service to the customers seeking water heater service or replacement. The truth is, most companies overcharge because they know you need hot water immediately and will probably pay a lot to get it quick. My typical customer is one who has price shopped the competition and have decided most companies either charge way too much or are hard to pin down to a firm price. We understand. You simply need a water heater and don’t want to deal with a sleazy salesman…you want to talk to a plumber….so give us a call and we’ll talk. At Better Water Heaters we do something quite rare in the plumbing business- install water heaters for a fair price. We grow our business one satisfied customer at a time; we don’t take advantage of a plumbing emergency and charge unreasonably. Your referral is important to us that is why we always will work to insure your complete satisfaction. We’re a small company and we keep our overhead low, because of this we don’t need to charge unreasonably. Of course we are licensed, bonded and insured and are very experienced at water heater installation and repair. We are experts in convention water heater repair and replacement, Tankless water heater installation, and other plumbing issues. We are the only water heater installation company in northern California that has earned the prestigious DIAMOND CERTIFICATION. We are also member of the Better Business Bureau. Our advertised prices include a quality water heater, basic installation and disposal of your old unit; Extra parts and labor required to do the job right, are additional. Call us for all your water heating needs. Estimates are always free and we never charge extra for nights, weekends, or holidays.
"Better Water Heater installed our tankless water heater incorrectly, creating a significant safety hazard for our tenant, an African American family of 5 with 3 small children. After a contractor from AHS reviewed the installation, they confirmed multiple issues, including code violations and fire risks. Major Problems with the Installation: Unsafe placement in a closet - The condensate has no proper drainage, which could lead to mold, rust, and fire hazards. Improper use of an evaporator pan - This pan is not intended for water heaters, creating a fire risk in an enclosed space. Oversized unit for our home - The Rinnai RU160iN is designed for larger homes. It's far too big for our 1-bed, 1-bath house, making it inefficient. Insufficient gas line - According to AHS, the gas line is too small to support this oversized unit, which could lead to gas flow issues or even pose a fire hazard. The city won't allow this installation to pass inspection because the gas line doesn't meet the required capacity. Permit/code violations - The installation was done without a permit and violates multiple building codes. When we confronted the company, they insisted their work was done correctly. Their "solution"? If we wanted the job to be done legally, we would have to pay for both the permit, their time working with inspectors, and additional costs to fix their mistakes--$995 for a bigger gas line to support the oversized unit. On top of that, they quoted us $585 for permit costs, even though the city building department told us the permit fee is only $150. Bottom Line: If you want a safe, legal, and code-compliant installation, DO NOT trust Better Water Heater. They cut corners, refuse accountability, and expect customers to pay extra to fix their mistakes."

"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

The average cost to repair an appliance depends on the appliance, make, model, the part that needs repair, and how long it takes to replace or repair a part. The following are the average repair costs for the most common appliances:
Refrigerator: $200–$300
Freezer: $90–$500
Oven, cooktop, range: $100–$500
Microwave: $50–$400
Dishwasher: $160–$300
Garbage disposal: $70–$250
Washing machine: $50–$450
Dryer: $100–$400
Appliance repair contractors may charge $40 to $120 per hour for labor, and most also provide the replacement parts necessary at an additional cost. It’s also important to note that these prices can go up on holidays and emergency fees may apply if you need your appliance fixed immediately.
The cost of home appliances ranges from $350 to $8,000 or more, depending on the brand, type of appliance, and features. Additional cost factors include any hookups that need to be installed, such as gas, plumbing, or electrical. Keep in mind that major appliances, such as refrigerators, washers and dryers, and water heaters, will cost more than minor appliances, such as microwaves, due to the size, complexity, and essential nature of the item.
