Tired of running out of hot water?

Are you tired of your hot water running out mid-shower or enduring lengthy waits for the water to heat up when you turn on the tap? These frustrations often stem from aging water heaters and indicate it’s time for an upgrade.

We understand that replacing your water heater can seem daunting, especially when you are weighing efficiency and comfort. California programs may offer rebates to help offset qualifying upgrades. With our rebate information, you can learn about incentives for efficient water heaters. Here at Drain Doctor Plumbing & Rooter, we’re committed to guiding you through the process and helping you make the most of available rebates when you invest in efficient, eco-friendly technology.

What is TECH Clean California?

TECH Clean California is an innovative statewide program aimed at promoting the adoption of clean space and water heating technologies. With rebates available for heat pump heating and cooling systems, including ducted heat pumps and ductless mini-split heat pumps, and now extended to include heat pump water heaters, it’s easier than ever to upgrade your home’s heating and cooling systems while taking advantage of incentives. Program rules and stackable incentives change over time—confirm current caps and eligibility on the official TECH Clean California site.

To qualify for these rebates, it’s essential to have your heat pump water heater installed by a certified TECH Clean California contractor. Drain Doctor is here to help you understand program requirements, explore heat pump water heater options for your home, and plan an installation path that aligns with rebate eligibility. Not only can you receive quality installation and service from our team, but you’ll also have clarity on how your project can meet state standards for energy efficiency.

Act soon: funds allocated for water heater rebates in California are limited and won’t be available indefinitely.

Heat pump water heater rebates

TECH Clean California’s rebate program for heat pump water heaters offers tiered incentives that depend on equipment size, fuel you are replacing, and program year. Larger tank-style units and certain configurations may qualify for higher incentives than baseline offers. Because published amounts change, treat this page as an overview and verify the latest figures with TECH Clean California or your installer before you commit.

Additionally, TECH Clean California has offered an Electrical Work Bonus to help with panel and wiring work that heat pump water heaters sometimes require. Percentages and caps are set by the program and update over time. Eligible electrical work can include replacement, upgrade, or relocation of the main service panel; installation of smart load centers or circuit breakers; sub panel installation; and upgrades to the feeder or secondary disconnects—confirm what qualifies under the current rules.

Heat pump water heater equity incentives

Residential customers who replace their existing natural gas water heater with a heat pump water heater may be eligible for additional equity incentives.

  • Single-family homes: income-qualified households may be eligible for additional equity incentives on top of standard heat pump water heater rebates. Amounts and caps are published by the program.
  • Multifamily properties: separate multifamily tracks apply with different calculation methods and per-project caps. Your property manager or contractor should review the current multifamily workbook.

For single-family homes (four dwelling units or less), residents must have household income that falls into one of:

  • Equal to or less than 80% of the median income in the area, or
  • Equal to or less than 250% of the federal poverty level.

To qualify for heat pump water heater rebates in California, customers typically must meet certain program requirements—such as enrolling in an eligible Demand Response (DR) program and being on a time-of-use rate plan. Heat pump water heaters must also meet eligibility criteria set by the program. We can help you understand these requirements as you plan your upgrade.

Can you come out the same day?

How do I schedule service?

Call (626) 332-9984, use the Request Service button on this site, or visit https://thedraindoctorcovina.com/contact-us/ to send a message—we follow up quickly.

What kinds of plumbing work do you do?

Drain Doctor Plumbing & Rooter handles residential and commercial plumbing, drain cleaning, hydro-jetting, camera inspections, water heaters, repiping, trenchless sewer repair, and more. The complete list is at https://thedraindoctorcovina.com/service/.

Why is my drain clogged or draining slowly?

Common causes include hair and soap in showers, food grease in kitchen sinks, foreign objects, or buildup deeper in the line—sometimes tree roots in the sewer. Store-bought chemicals rarely fix the real problem and can damage pipes. Drain Doctor Covina diagnoses with video pipe inspection when needed, then clears or repairs the line properly. Call (626) 332-9984 for help.

My shower drain is clogged or the bathtub is not draining—what should I do?

Stop using fixtures that tie into the same line to avoid backups. For a slow draining sink or stubborn shower clog, professional drain cleaning or hydro jetting clears the blockage safely. Drain Doctor Plumbing & Rooter offers same-day service in Covina and nearby—call (626) 332-9984.

What are signs of a sewer line backing up?

Gurgling toilets, multiple drains acting up at once, sewage smells, or water backing up in tubs or floor drains can mean a main line problem. Sewer line inspection with a sewer camera finds the cause—whether it is a clog, bellied pipe, or root intrusion—so Drain Doctor Covina can recommend sewer repair or cleaning. Call (626) 332-9984 to schedule.
