Most maintenance checklists fail for the same reason most budgets fail: they are built for an ideal week that never arrives. A schedule works when each task is small enough to finish in one sitting and tied to a season you cannot forget.
Here is a version organized that way, with rough time and cost for each item.
Spring
Spring work is about undoing winter and getting ahead of cooling season.
- Service the AC before the first hot week. A tune-up runs $80–$180. Waiting until the first 95-degree day means a two-week queue and emergency pricing.
- Clear gutters and downspouts. One to two hours, or $150–$300 hired out. Water that backs up over the fascia is the cheapest problem to prevent and one of the most expensive to repair.
- Walk the roof line from the ground with binoculars. Look for lifted shingles, exposed nail heads, and cracked boot flashing around vent pipes. Photograph anything that looks off, with the date.
- Check exterior caulk and door seals. A $6 tube of sealant around window trim does more for a summer power bill than most people expect.
- Test the sump pump by pouring a bucket of water into the pit. Ten minutes.
Summer
- Change HVAC filters monthly during heavy run time. Not quarterly. A clogged filter is the most common cause of a frozen coil.
- Flush the water heater. Thirty to forty-five minutes. Sediment is what kills tanks early, especially on hard water.
- Inspect the deck, fence, and exterior wood. Probe soft spots with a screwdriver. Rot spreads in one season and gets expensive in two.
- Clean dryer vent ductwork, not just the lint trap. $100–$200 professionally, and a genuine fire risk when neglected.
- Trim vegetation back from the foundation and AC condenser. Two feet of clearance minimum.
Fall
- Service the furnace or heat pump. Same logic as spring AC service, same pricing, same queue problem in reverse.
- Shut off and drain exterior hose bibs in any climate that freezes. A burst pipe behind a wall is a five-figure claim from a five-minute task.
- Clean gutters again after leaf drop. Yes, twice a year.
- Reverse ceiling fans to clockwise on low.
- Test every smoke and CO detector, and replace batteries on a fixed date so you never have to remember the last one.
Winter
- Watch for ice dams and interior ceiling stains. Catch them while they are still a stain.
- Check attic insulation depth and ventilation. A cold attic that stays cold is working correctly.
- Run seldom-used faucets and flush unused drains so traps do not dry out.
- Inspect the water heater relief valve and the area around the tank for corrosion.
- Review your insurance coverage against what you actually own now. This is the quietest, most valuable winter task on the list.
Annual and every-few-years items

| Chimney sweep and inspection | Annually if used | $150–$400 |
| Water heater replacement | 8–12 years | $1,200–$2,600 |
| Roof inspection | Annually after year 10 | $0–$300 |
| Termite inspection | Annually in the South | $75–$150 |
The part most people skip
Doing the work is only half of it. Recording it is what turns maintenance into an asset.
Write down what you did, when, what it cost, and who did it. Photograph the model plate on anything you replace. Keep the invoice. Five years from now, those notes answer questions you cannot answer any other way: is this still under warranty, has this been serviced since we moved in, what did we pay last time, and who do I call.
That record is also what an insurance adjuster wants after a storm, what a buyer’s agent asks for at closing, and what saves you from paying twice for the same repair.
