25C Eligible Systems

What Is the 25C Tax Credit?
The 25C tax credit is a means for the federal government to incentivize energy efficiency by offering tax credits for installing qualifying upgrades in your home. While your specific tax credit can vary, 25C offers as much as $3,200 in a single tax year.
Fast Facts about 25C
Eligibility
25C tax credits apply to your primary residence, not additional properties you don’t live in, like rentals or vacation homes. However, there are tax credits available for certain improvements for second homes.
Also, keep in mind that you’re only eligible for a tax credit if you have tax liability – meaning you owe taxes at the end of the year. If you don’t owe anything, you won’t have money added to your tax refund.
The eligible upgrades include:

Air Conditioning
- 30 % of the project cost up to $600 maximum
- Split systems must be ENERGY STAR® certified with SEER2≥ 16
- Packaged systems must be ENERGY STAR® certified with SEER2 ≥ 15.2, EER2 ≥ 11.5

Heat Pump
Heat pumps are a leading way to heat and cool your home more efficiently. Instead of burning fuel to generate heat, heat pumps transfer heat energy in either direction to provide cooling or heating in all seasons.
Appliances like heat pumps are ranked according to CEE tiers. Higher tiers represent higher levels of efficiency. Air source heat pump efficiency is measured in Heating Seasonal Performance Factor (HSPF), which is the heat output divided by the electricity used over the heating season (BTUs per watt-hour).
Electric or natural gas heat pumps may be eligible for up to $2,000, but they must meet the highest efficiency standards available at the time you claim the credit. This typically means ENERGY STAR® appliances with CEE tiers of 1, 2, or 3.
- Air source heat pumps have additional requirements:
- 30% of the project cost, up to $2,000 maximum
- Ducted split systems must be ENERGY STAR® certified with HSPF ≥ 7.8, SEER2 ≥ 15.2, EER2 ≥11.7
- Packaged systems must be ENERGY STAR® certified with SEER2 ≥ 15.2, EER2 ≥ 11.5
- Ductless mini-split (non-ducted) systems must be ENERGY STAR® certified with SEER2 ≥ 16, EER2 ≥ 12, HSPF2 ≥9

Insulation and Air Sealing
Insulation and air sealing, otherwise known as weatherization, prevent heating and cooling loss from leaks. You may be able to claim credit for weatherization materials like:
- Insulation batts
- Blow-in insulation fibers
- Rolls of insulation
- Expanding spray foam insulation
- Rigid boards of insulation
- Foam-in-place insulation
- Specialized caulk, tape, foam, and sealants
All weatherization supplies must meet the Department of Energy’s recommended R-values for your climate zone to qualify for a tax credit.

Water Heaters
To qualify for a tax credit, all weatherization supplies must meet the Department of Energy’s recommended R-values for your climate zone. Heat pump water heaters also qualify for an increased annual credit limit of $2,000.

Jesus Gloria AC service review. He did a great job today and I would highly recommend him for any AC service needs. He was very knowledgeable and courteous. He helped add a surge protector on my outside unit for added protection. I look forward to working with him in the future.
Well, I had some plumbing issues at my residence, and I called "Goettl Plumbing." Great results, too 🤗.
My water wouldn't stay hot, and after contacting Justin at Goettl Plumbing, he sent out Frank, a service technician with over 20 years of plumbing experience. Frank spent a good bit of time studying/ evaluating my plumbing functions, consulted with an on-site Goettl supervisor, and determined my plumbing issues.
After they conferred those issues with Justin, a plan for resolution and payment was determined, and work started the next day.
Greg arrived that morning; accessed the work areas, determined the tools and equipment he needed, and got right to work.
By the end of the day, Greg had installed three (3) Replacement Single Handle Tub/Shower Valves, a Pressure reducing valve, and a Thermal expansion tank with vacuum breaker - - RESULTS: Hot Water 💧
In two days, I witnessed Super Communication, Super Teamwork, and some old-time "1990-1991" Professionalism ... thanks,
"GOETTL Air Conditioning & Plumbing" for A Job Well Done 👏🏼
After note. Cameron came back by a day later to check on readings he wasn't able to get on first appointment. I have high confidence in his work. I'm very likely to work with them again
Brayan and Marcos did an awesome job on the new ac installation. Installed with no issues and has been on ever since. Perfect time with summer coming up. Walked through and job was very clean and organized. Great work ethic. Great guys.
Update - our air conditioner went out today (10/26/23) and JEHAD showed up to repair the issue but the issue was bigger than expected. Tomorrow we will have a brand new system! Goettl is an EPIC firm that treats customers right. Thank you again JEHAD for going above and beyond.
Goettl is the epitome of what excellent customer service is! Our Drain King, DAREAN, addressed all of our questions and concerns and not only unclogged our drain but went above and beyond to show us our drains leading to the street were free and clear of any other issues. Thank you Darean and thank you Goettl for a great experience!
Update: great experience with Edgar Loredo who kept it real with us and was very transparent. I appreciate his honesty and recommendations. Will be requesting him as our technician in the future if we choose to use Goettl

We had an blockage in our sewer line.
Tyler Leija was dispatched the same day, and found the blockage using a camera tool.
He cleared the blockage temporarily.
The actual fix would require digging up and replacing the bad area of pipe.
Paulo "Adrian" Dado and his crew came out the next day with backhoe, dug up the area, and replaced the section of pipe.
The next day, after inspection, Adrian and his crew filled in the hole and then cleaned up the area.
This is a brief description. There was A LOT of work involved.
Very professional work.
Our tech Jorge that came out the day before helped quickly assess the situation and get us set up for a new system and water heater. Jorge was very friendly, would highly recommend!
Frank did an excellent job at explaining every thing in terms that were understandable to both myself and my wife. This greatly assisted in making the right decision to look at all options on either repair or update/purchase for the future and in the long term, saving money.
Will definitely call and use
Goettle again and I will ask if Darrean could help again.
Couldn’t be happier. Came all the options

Our Story
It all started with a flashlight.
Our CEO, Ken Goodrich, was a 10-year-old boy holding a flashlight for his dad as he worked on an air conditioner for a customer. His father was an independent technician in Las Vegas who admired the longevity and quality of Goettl products. In 2013, Goodrich purchased Goettl Air Conditioning & Plumbing and has since expanded the company across Arizona, Nevada, and Texas.
