Tax Inquiry: $12k to replace AC

[Terri P.]

It’s time to replace one of those higher cost items in a rental: the air conditioning system. I was quoted $12,000. The system is 15 years old and the climate here in Northern California can get over 100 F in the summer months.

The alternative is to replace the control board which is $1150. But I was advised (by AC company) that it’s an older unit so it will continue to give me issues in the future.

I am considering replacing the system but was wondering how beneficial this is for my income tax write offs. Still a newbie in the home rental market so not sure. I have a day job so the rentals help with my W2 income tax returns. My questions:

1) is there a max on how much I could claim in a tax year for each rental property?

2) should I ask for a payment plan or pay for the AC unit in full to maximize my tax return for 2025?

3) loan through the AC Company is 6.5% interest for credit scores over 700 (I’m north of 800)

I’ve always been the DIY person but recently had to pay to get my taxes done. May need to hire a tax advisor. 

Thanks for your input!

Hi 

I am not a tax pro, but i think this is accurate:

1. How you pay/finance HVAC unit has no bearing on tax

2. If you buy HVAC for 12k it is capital improvement and needs depreciated

3. If you replace control board and it's less than $2500 it's expenses.
