I'm going to be honest with you: I know all of this. I know I'm supposed to get the HVAC tuned up before summer, clean the gutters after the leaves fall, flush the water heater once a year. I have the list. What I don't always have is the time, the headspace, or the energy after keeping up with the laundry, packing the kids' lunches, thinking about what to make for dinner, and just... existing.
If you're reading this and feeling a little behind? Same. You're in good company.
This is the full-year calendar for DMV homeowners, organized by season and built for our climate. Most of these tasks are inexpensive but skipping them is not. The rough industry rule is about four dollars in repair for every dollar of upkeep you put off, which is why a calendar beats a memory. For what the year actually adds up to, see what home maintenance actually costs.
Skim it, print it, or hand it to someone else to deal with. Whatever works. (No judgment on that last one.)
The home maintenance calendar at a glance
Here's the maintenance calendar, season by season. Some tasks come once a season, some are monthly, and that rhythm matters as much as the tasks themselves. The last column flags what most homeowners can handle themselves and what's worth a professional.

Spring: get ahead of the humidity
DMV summers arrive humid and fast. Spring is the window to get your cooling system checked before the first sticky week, while technicians still have open calendars. That won't be true by July.
The high-value task here is the cooling tune-up. A technician checks the parts that fall out of whack over winter and catches small failures before they become expensive ones. And once that's done it's time to clear the gutters after the pollen and seed drop so the first big thunderstorm drains where it should. Re-open the outdoor spigots, look for any splits left by winter, and run the sump pump once before storm season runs it for you.
Spring maintenance is mostly about being one step ahead, and honestly it's one of those things you'll be really glad you did.
Summer: the high-load months
From June through September, DMV dew points regularly sit above 70 degrees. Your air conditioner is working hard, and the filter loads up faster than the box suggests. Check it monthly. Change it every one to three months through the humid stretch. A clogged filter makes your system work harder than it needs to and shortens its life. It's one of those small things that actually matters.
Clear the condensate drain line so a clog doesn't back up into the unit. Summer is also the right time for the jobs that need warm, dry weather: reseal a deck or fence if it's due, vacuum the refrigerator coils, and test your smoke and carbon monoxide detectors. (We know, we know. But it really does only take two minutes and you'll feel so much better having done it.)
Fall: close the house down right
Fall is the mirror of spring, and it's just as important. Book the heating tune-up before the first cold snap (same logic as spring: technicians are busy once the temperature drops). Do the big gutter clean after the leaves finish falling. If you're in one of the older, tree-lined neighborhoods around Bethesda, Arlington, or Northwest DC, this is the most important exterior job of the year so don't skip it.
Before the first hard freeze, shut off and drain the outdoor spigots. A trapped inch of water can split the pipe behind the wall and make for a very bad morning. While you're at it, replace any worn weatherstripping. It's the cheapest comfort upgrade there is and most people put it off forever.
Winter: protect, plan, and breathe a little
Winter work is mostly about watching and protecting. On the coldest nights, keep an eye on the pipes along exterior walls and in unheated spaces, and make sure you know where your main shutoff is. (Do you know where it is? Most people find out during a burst pipe, which is not the ideal moment. Worth locating it now while things are calm.)
Flush the water heater once a year to clear sediment and add years to the tank. Test the GFCI outlets in kitchens, bathrooms, and the garage. And then, genuinely, use winter as the quiet season to think ahead. Look at what's aging in your home and budget the bigger replacements before they decide the timing for you. Your roof, your HVAC, your water heater: none of them will give you much warning. They're not big on advance notice.
How often should each task happen?
A simple way to hold the whole calendar in your head is to think in rhythms:
- Monthly: check and change air filters.
- Each season: HVAC tune-up, gutters, outdoor spigots.
- Once a year: flush the water heater, test detectors and GFCI outlets, check the exterior envelope.
- Every few years: reseal decks and fences, start planning for the big-ticket replacements.
For the reasoning behind each task (why it matters, what happens if you skip it), the system-by-system preventative guide walks through all of it.
Print the checklist
The calendar above is yours to use. If you want it somewhere you'll actually see it, the printable one-page version is sized for the fridge or the inside of a cabinet door.
And if the list feels like a lot...
It kind of is. That's the honest answer. A full year of home maintenance isn't complicated, but it does require remembering things, scheduling things, and following through, and most of us already have enough of that going on.
And here's the thing: even if you nail every task on this list, it's still just the surface. A truly well-maintained home has a lot more going on: systems and details that don't make it onto seasonal checklists but absolutely affect how your home ages and what it costs you. We're not saying that to overwhelm you. We're saying it because most homeowners just don't know, and we'd rather be the people who tell you.
If you'd rather hand it off, that's exactly what we're here for. You can have someone run the calendar for you, get a sense of what your home's annual costs look like, or just talk it through with no pressure. There's no wrong answer. The home gets looked after either way, and you get your Saturdays back.
What should be on a home maintenance checklist?
At minimum: seasonal HVAC tune-ups, monthly filter changes, gutter cleaning in spring and fall, outdoor spigot care around the first and last freeze, a yearly water heater flush, and detector and GFCI tests. The exact timing depends on where you live. In the DMV, humidity and freeze-thaw cycles set the calendar more than the date on its own does.
What is the difference between a home maintenance checklist, a schedule, and a plan?
A checklist is the list of tasks. A schedule, or calendar, is that list with timing attached, so each task lands in the right season. A maintenance plan goes one step further and adds who does each job and what it costs, so nothing depends on you remembering. The calendar on this page is a schedule. Turning it into a plan is what a service like ours handles.
How often should I do home maintenance?
Think in four rhythms. Monthly for air filters. Seasonally for HVAC tune-ups, gutters, and spigots. Yearly for the water heater flush, detector tests, and exterior checks. Every few years for resealing decks and fences and planning the major replacements. Most homes need only a few hours of attention in any given month.
Is there a home maintenance checklist for my climate?
Yes, and it matters. The DMV sits in USDA Zone 7a, humid subtropical, with summer dew points regularly above 70 degrees and real winter freezes. That combination loads HVAC systems harder in summer and puts outdoor plumbing at freeze risk in winter, so the calendar here is timed to this region rather than copied from a generic national list.
I just bought my first home. Where do I start?
Start with the systems that are expensive to fix and easy to ignore: get the HVAC tuned, find and label your main water shutoff, change the filters, and clear the gutters. Then put the seasonal calendar somewhere you will actually see it. You do not have to do everything at once. You have to not skip the cheap things that prevent the expensive ones.
Do I have to do all of this myself?
No. Plenty of homeowners would rather not, and that is exactly what a maintenance plan is for. Our memberships put the whole calendar on someone else's desk: scheduled visits, the seasonal tune-ups, and one person who keeps track so you do not have to. Current plan details are on the membership page. You can estimate the cost for your home with our calculator, or book a home assessment to start.
