Spring home checklist and leak-check record

Quick answer

Do the spring list on the weekend the clocks go forward, March 14, 2027. Book the cooling check-up first, since ENERGY STAR says contractors get busy once summer comes. Then read the date on the back of each smoke alarm and replace any that are 10 years past it, test every smoke and CO alarm, and look at the HVAC filter. Finish with EPA's leak check: read the water meter, use no water for two hours and read it again. If the number moved, you probably have a leak, so write it down and call a plumber or your landlord.

Do it, skip it or get help

Do it yourself

Do the checks and the notes yourself

Reading alarm dates, pressing test buttons, looking at the filter, reading the water meter and dropping food coloring in a toilet tank take a step stool, a flashlight and an afternoon.

Skip it

Skip the rows that aren't yours

No sprinkler system, no hoses, no central air: leave those rows blank. In an apartment without its own water meter, skip the meter rows and keep the toilet and faucet checks.

The work goes to a pro or the landlord

The cooling check-up is contractor work. So is fixing any leak you find, and EPA points to a WaterSense certified irrigation pro for sprinkler systems. Anything on the roof or at gutter height is booked work too. This page only tells you what to check and what to write down.

The steps, in order

  1. Pick the weekend

    Put the list on the weekend the clocks go forward. In 2027 that is Sunday, March 14. ENERGY STAR suggests the time changes as the cue for the check-ups.

    Have ready: The printed working copy and your phone calendar

  2. Book the cooling check-up

    Call before the first hot week. ENERGY STAR says contractors get busy once summer arrives and recommends a yearly check-up before the season. Renters ask the landlord when it's booked.

    Have ready: The air conditioner or heat pump model number from your appliance log

  3. Read the date on each smoke alarm

    Take each alarm down and read the date of manufacture on the back. USFA says to replace a smoke alarm 10 years from that date. Put the younger ones back up.

    Have ready: A step stool and a list of where each alarm is

    Source: USFA, Don't wait, check the date handout, checked October 12, 2026.

  4. Test every smoke and CO alarm

    Press each test button until the alarm sounds. NFPA says to test smoke and CO alarms at least once a month, so this counts as March's test. Write the date for each one.

    Have ready: A helper in the farthest bedroom to say whether they heard it

  5. Look at the HVAC filter

    Pull the filter and hold it to the light. ENERGY STAR says to inspect, clean or change it once a month. If you change it, write the date on the new frame.

  6. Run the two-hour meter check

    Read the water meter and write the number down. Use no water for two hours, then read it again. EPA says that if the meter changes at all, you probably have a leak.

    Have ready: A flashlight for the meter box and a two-hour stretch when nobody is home or showering

  7. Check each toilet with food coloring

    Put a few drops of food coloring in the tank and wait 10 minutes without flushing. Color in the bowl means the toilet leaks. Flush when you're done so the tank doesn't stain.

    Have ready: Food coloring and a timer

  8. Note drips and the sprinkler question

    Look for water on the outside of faucets and pipe fittings and list each spot. If you have an in-ground sprinkler system, EPA says to check it each spring before use for frost damage, so book that before the first run.

  9. Book the fixes and file the sheet

    Call a plumber, the irrigation pro or the landlord for anything you found, and write the date you called. Then file the sheet in the binder behind last fall's page.

What goes wrong

The cooling check-up gets booked in the first heat wave

ENERGY STAR notes that contractors get busy once summer comes. A call on the March time change comes before that rush.

An alarm past its date stays on the ceiling

An old alarm can still sound when you press the button, so the test alone won't tell you it's due. USFA says to replace it 10 years from the date on the back.

A slow leak runs all year

A silent toilet leak doesn't show up until the bill does. EPA says the average household's leaks can waste more than 9,300 gallons a year, and nine percent of homes leak 50 gallons or more a day.

The sprinklers come on with winter damage

EPA says a sprinkler leak 1/32 inch across, about the thickness of a dime, can waste about 6,300 gallons a month. Book the spring check before the first watering day.

The meter check runs while someone uses water

An ice maker refilling, a dishwasher cycle or a shower in those two hours moves the meter too. Turn off what you can and start again if anyone uses water.

When the steps change

Variant 01

Renting

Keep the alarm, filter and toilet rows if those are yours. Ask the landlord when the cooling check-up is booked and who reads the meter. Report any leak in writing and note the date on the sheet.

Variant 02

Hawaii and most of Arizona

NIST lists Hawaii and most of Arizona among the places that don't change their clocks. The list still works: do it on the second weekend of March anyway.

Variant 03

On a hurricane coast

Ready.gov lists the Eastern Pacific season from May 15 and the Atlantic season from June 1. Add a row to read the Ready.gov hurricane page and check your supplies before your coast's season opens.

Source: Ready.gov, hurricanes, checked October 12, 2026.

Variant 04

Apartment without its own meter

Skip the two-hour meter check. The food coloring test and the look at faucets and fittings still work. Report anything you find to the landlord in writing.

Two meter readings, two hours apart, with no water running in between. Write both on the sheet.

Tips and tricks

  • Tip 01

    Photograph the meter both times

    A phone photo of each reading saves you from misreading the small dial later, and it timestamps the two hours for you.

  • Tip 02

    Run the meter check while you're out

    Read the meter as you leave for errands and again when you get back. Nobody uses water while the house is empty.

  • Tip 03

    Mark each alarm with its replace year

    When you read the date on the back, add 10 years and write that year on the sheet next to the alarm's room. Next spring you only read the sheet.

    Source: USFA, Don't wait, check the date handout, checked October 12, 2026.

  • Tip 04

    Book cooling and sprinklers in the same hour

    Make both calls in one sitting on the time change weekend. Write each booked date on the service log right away.

  • Tip 05

    Keep last fall's page next to this one

    The fall sheet says where the hoses went and which windows were drafty. Read it before you start, so nothing gets checked twice.

What we would do

Put March 14 in your phone now, then do the list that weekend

Set a reminder for Sunday, March 14, 2027. That weekend, make the cooling call first, then walk the house with a step stool for the alarms and the filter, and run the meter check while you're out on errands. Any leak you find goes to a plumber or the landlord the same week.

Questions

What should be on a spring home maintenance checklist?

Booking the cooling check-up, reading the date on each smoke alarm, testing every smoke and CO alarm, looking at the HVAC filter, and a leak check: the two-hour water meter test and food coloring in each toilet tank. Add a sprinkler check if you have an in-ground system. Each row gets a date.

When should I do spring home maintenance?

The weekend the clocks go forward works well. ENERGY STAR suggests the time changes as the reminder for the check-ups, and in 2027 the clocks go forward on Sunday, March 14.

Source: ENERGY STAR maintenance checklist, checked October 15, 2026; NIST, daylight saving time rules, checked October 12, 2026.

How do I check my house for a water leak?

EPA's method: read the water meter, use no water for two hours, then read it again. If it changed at all, you probably have a leak. For toilets, put a few drops of food coloring in the tank; color in the bowl after 10 minutes means a leak. Fixing it is a job for a plumber or the landlord.

When is EPA's Fix a Leak Week?

EPA holds it every March. In 2026 it ran from March 16 to 22. Doing your own leak check on the time change weekend puts it in the same month.

Source: EPA WaterSense, Fix a Leak Week, checked October 15, 2026.

Do renters need a spring checklist?

A shorter one. Renters usually keep the alarm, filter and toilet rows, ask the landlord about the cooling check-up and the meter, and write down the date they reported any leak.
