Closing day in Las Vegas is the finish line for the buying process and the starting line for something most new owners underestimate: the desert is hard on houses, and your first 90 days set the tone for the next decade of repair bills. Heat that tops 110°F, some of the hardest tap water in the country, monsoon microbursts, blowing dust, and relentless UV all work on your home in ways a buyer relocating from a milder climate has never had to think about. The good news: a short, front-loaded checklist in your first three months prevents the expensive surprises — a $6,000 AC failure in July, a water heater scaled shut at year three, an irrigation leak quietly running up a four-figure water bill.
Across our 9,600+ closings at Nevada Real Estate Group since 2011 — including the 789 homes we closed in 2025 as the #1-ranked team in Nevada — the single biggest predictor of a happy first year is whether the owner did the boring maintenance in the first 90 days or waited until something broke. This is the checklist we hand our buyers at closing, sequenced week by week and month by month, with real Las Vegas costs. Keep our line handy — (702) 637-1759 — and let's protect the biggest asset you own.
In your first 90 days as a Las Vegas homeowner, tackle the desert's four killers: service the HVAC and set a 30–60 day filter habit, flush the hard-water scale from the water heater, inspect the roof and seals before monsoon season, and audit the drip irrigation for leaks. Add a pest baseline, register every warranty, and budget $2,000–$4,000 for year-one upkeep. Do the boring work early and you skip the expensive July surprises.
- Service the AC and change filters every 30–60 days — desert dust clogs them 2–3x faster than a mild climate.
- Las Vegas tap water is very hard (~16+ grains); flush the water heater and consider a softener to protect fixtures.
- Inspect the roof and exterior seals before monsoon season — microbursts find every weak flashing.
- Audit drip irrigation for leaks and set timers to SNWA's seasonal watering schedule to avoid four-figure water bills.
- Register builder, appliance, and home warranties in the first weeks — and budget $2,000–$4,000 for year-one maintenance.
Why Does a Las Vegas Home Need a Different Maintenance Plan?
A house in the Mojave Desert ages on a different clock than one in a temperate climate, and the maintenance that matters most is climate-specific. According to NV Energy, Southern Nevada summers push air conditioners to run nearly around the clock for months, so your HVAC does more work in one Las Vegas summer than a northern system does in two years. According to the Southern Nevada Water Authority, local tap water is among the hardest in the nation, which scales water heaters and fixtures from the inside out. Add intense UV that degrades roof underlayment and exterior paint, monsoon microbursts that stress flashing, and fine dust that clogs filters — and you have a maintenance profile no relocating buyer has managed before.
This matters most for the thousands of buyers moving to Las Vegas each year from California, the Pacific Northwest, and the Midwest. The maintenance instincts that served you in a temperate climate don't transfer: a roof that lasts 30 years back east bakes faster here, a water heater that ran a decade elsewhere scales shut sooner, and a lawn-watering schedule that made sense in a wetter region will both waste money and break local rules. None of that is a reason to worry — it's just a different playbook, and it's learnable in an afternoon. Newer master-planned areas across the valley, from the communities of the northwest to the southeast, all share the same desert fundamentals, so the checklist below applies whether you bought in an established neighborhood or a brand-new subdivision.
In our experience, the owners who struggle are the ones who apply their old-climate habits here: changing the filter twice a year, ignoring the water heater, watering on a summer schedule in January. The desert punishes deferral. The checklist below is sequenced so the highest-consequence, lowest-cost tasks come first — because a $20 filter and a $120 AC tune-up prevent a $6,000 compressor failure, and that math is the whole game. Whether you bought resale or new construction, the first 90 days are when you build the habits that keep your home out of the emergency-repair cycle.
What Should You Do the First Week After Closing?
Week one is about safety, security, and a baseline. Before the furniture arrives, walk the house with this list — most of it is free or under $50, and it's the highest-leverage day you'll spend on the home all year.
| Task | Why it matters here | Typical cost |
|---|---|---|
| Re-key or replace locks | You don't know who has old keys | $15–$40 DIY · $120+ locksmith |
| Change every HVAC filter | Movers stir up dust; start the 30–60 day clock | $15–$40 |
| Locate + test the main water shutoff | A burst line in summer heat is a fast disaster | $0 |
| Label the breaker panel | Nobody labeled it for you | $0 |
| Test smoke + CO detectors | Batteries are often years old | $20–$40 |
| Find the irrigation controller + valves | Desert yards live or die on the drip system | $0 |
| Deep-clean before furniture | Easiest access you'll ever have | $0–$300 |
According to Nevada Revised Statutes and Clark County code, a re-key is entirely your right as the new owner, and it is the one security task no buyer should skip. Photograph the breaker panel, the water heater's data plate, and the HVAC model numbers now — you'll want them when you register warranties and when a technician asks over the phone.
Which HVAC Tasks Come First in the Desert?
Your air conditioner is the most important — and most expensive — system in a Las Vegas home, so it leads the list. According to ENERGY STAR, a professional HVAC tune-up runs about $80–$150 and should happen before peak cooling season; in the desert, we tell owners to book it in their first month regardless of the calendar. A tune-up checks refrigerant charge, coils, the capacitor, and airflow — the exact parts that fail catastrophically in July when you can least afford it.
Then build the filter habit: change or clean filters every 30–60 days, not the twice-a-year cadence that works back east. Desert dust loads a filter two to three times faster, and a clogged filter makes the system work harder, spikes your NV Energy bill, and shortens the compressor's life. Set the thermostat schedule for real desert living (a modest setback while you're out, not a 15-degree swing the AC can't recover from), and if the home has an older single-speed system, start pricing a high-efficiency replacement before it dies on its own terms. According to the U.S. Department of Energy, cooling is the largest slice of a desert home's energy bill, so this system is where maintenance pays back fastest.
How Do You Protect Against Hard Water in Las Vegas?
Las Vegas tap water runs roughly 16 grains per gallon or higher of hardness — among the hardest in the country, according to the Southern Nevada Water Authority. That mineral load scales the inside of your water heater, clogs faucet aerators and shower heads, spots your glass, and shortens the life of every water-using appliance. Two first-90-days moves protect you.
First, flush the water heater. Sediment and scale settle in the tank and rob efficiency; draining and flushing it (a DIY job or $100–$200 with a plumber) in your first month, then annually, adds years to its life. Second, consider a whole-home water softener. A softener runs $800–$2,500 installed and pays for itself in longer appliance life, fewer plumbing repairs, and less soap and detergent — most Las Vegas owners who install one wish they'd done it sooner. At minimum, replace scaled aerators and shower heads (a $10–$30 fix that restores water pressure) and keep the dishwasher and washing machine on the maintenance schedule the manufacturer specifies for hard water.
What Roof and Exterior Checks Matter Here?
Monsoon season — roughly July through September — brings microbursts with 60-plus mph gusts and driving rain, and they find every weak point on a roof that UV has been degrading all year. According to the Clark County Department of Building, roof and exterior permits are among the county's steady categories precisely because desert roofs need attention. Before monsoon season, walk the exterior (or hire a roofer for $150–$350) and check for these:
- Tile or flat-roof condition — cracked tiles, blistered flat-roof coating, and worn underlayment. A flat/foam roof may need recoating every 5–10 years ($1,500–$4,000).
- Flashing and seals around vents, skylights, and the AC curb — the first places a microburst drives water in.
- Stucco cracks and exterior caulk — UV opens hairline cracks that let water and pests in.
- Gutters and grading — even in the desert, monsoon volume overwhelms poor drainage and pushes water toward the foundation.
Register any findings while you still may have recourse — a resale home's disclosures or a builder's warranty may cover a defect you catch in the first 90 days but not one you report at year two. For a deeper seasonal walk-through, our companion guide to surviving your first desert summer covers the heat-specific tasks in detail.
How Should You Handle Desert Irrigation and Landscaping?
In a Las Vegas yard, the irrigation system is life support — and a hidden leak is one of the most expensive problems a new owner can miss, because it runs silently and shows up only on the water bill. In your first weeks, run each irrigation zone manually and watch for leaks, broken emitters, geysering heads, and dry spots. According to the Southern Nevada Water Authority, set your controller to the seasonal watering schedule — Southern Nevada restricts watering days by season, and running a summer schedule year-round both wastes water and violates the assigned-day rules that carry fines.
A few first-90-days landscaping moves protect your investment and your budget: audit the drip system for leaks (a $75–$150 service, or free if you DIY the walk-through), replace broken emitters and check the timer's rain/seasonal settings, and take advantage of SNWA's Water Smart Landscapes rebate if you're converting grass to desert landscaping — the rebate can offset a meaningful share of the conversion cost. If your home has mature desert plants, a light first-season trim keeps them off the stucco (where they invite pests) and out of the roofline.
There is a resale angle here too, not just a maintenance one. In our experience listing homes across the valley — including the higher-end guard-gated communities where landscaping is scrutinized — the yards that show best and appraise cleanest are the ones on a real irrigation and trim schedule, not the ones patched up the week before listing. A drip system with visible leaks, dead zones, or overgrown plants reads to a buyer as deferred maintenance and invites a lower offer. Setting the schedule and fixing the emitters in your first 90 days isn't only about the water bill; it's the cheapest curb-appeal investment you can make, and it compounds every year you own the home. Take a photo of the controller settings once they're dialed in so a house-sitter or the next owner can replicate them.
What Pest-Control Baseline Should a New Owner Set?
Desert homes share the neighborhood with scorpions, roof rats, ants, and the occasional snake, and the first 90 days are when you set the baseline that keeps them outside. According to University of Nevada, Reno Extension and Clark County vector guidance, the most effective pest control in the desert is exclusion — sealing the gaps — not just spraying.
Walk the exterior and seal the entry points: weep screeds and stucco gaps, garage-door thresholds, weatherstripping on exterior doors, and any penetration where a pipe or wire enters the wall. A door sweep and a tube of exterior sealant is a $30 afternoon that does more against scorpions than any spray. Then set a quarterly pest service ($100–$200 per visit, or roughly $40–$60/month on a plan) with a company that treats for desert-specific pests. New owners with kids or pets often add a scorpion-specific UV-light night check in the first weeks to gauge the pressure. Our full Las Vegas scorpion and pest homeowner guide walks the exclusion checklist room by room.
Which Warranties and Documents Should You Register?
Warranties are only worth what you register, and the clock starts at closing. In your first weeks, gather and file:
- Builder / structural warranty (new construction) — most cover workmanship for a year, systems for two, and structure for ten; register your contact info and note the reporting deadlines.
- Appliance and HVAC warranties — register each unit's serial number online; many extend coverage just for registering.
- Home warranty (if you bought one or the seller provided it) — know exactly what it covers and the service-call fee before something breaks.
- Closing packet + inspection report — keep the seller's disclosures and your inspection report; they're your record if a defect surfaces early.
According to HUD, keeping organized homeownership records is one of the simplest ways to protect your investment and your resale position. Snap photos of every data plate and store the paperwork (physical and digital) in one place — the warranty you can't find is the warranty you don't have.
What Are the Days 30–60 Maintenance Tasks?
With week-one safety and the big-four systems handled, days 30–60 are about dialing in the systems and catching what you missed while unpacking. This is also when you meet your utility bills for the first time and can adjust. Change the HVAC filter again (you're on the desert cadence now), test the irrigation on its new seasonal schedule, and do a slow walk-through looking for the small stuff: running toilets, drippy hard-water faucets, weatherstripping gaps, and garage-door balance. It's also the window to shop insurance — pairing your maintenance baseline with the right coverage matters, and our Las Vegas homeowners insurance guide explains how desert risks price into your policy.
Your first full summer electric bill will get your attention, and days 30–60 are when you can still do something about it before the worst of the heat. According to the U.S. Department of Energy, small efficiency moves compound in a climate that runs the AC this hard: add or check attic insulation, seal duct leaks and weatherstrip doors, install a smart or programmable thermostat, and consider solar screens or a reflective film on west-facing windows that take the afternoon sun. Ceiling fans let you run the thermostat a few degrees warmer at the same comfort. None of these are urgent repairs, but done in your first months they lower every bill for as long as you own the home — and they make the house more comfortable through a desert August, which is the whole point of getting the maintenance right early.
What Belongs on the Days 60–90 List?
By days 60–90 you're establishing the seasonal rhythm you'll keep for years. Here is the full first-quarter timeline in one place so you can see how the tasks sequence — the columns are your three checkpoints, not a suggestion to wait.
| System | By Day 7 | By Day 30–60 | By Day 60–90 |
|---|---|---|---|
| HVAC | New filters; find the unit + model # | Professional tune-up; filter again | Set seasonal thermostat schedule |
| Water | Test main shutoff | Flush water heater; fix scaled fixtures | Decide on a softener |
| Roof / exterior | Visual scan for obvious damage | Pre-monsoon roof + seal check | Recoat/repair as needed |
| Irrigation | Locate controller + valves | Leak audit; set seasonal schedule | Rebate conversion if applicable |
| Pests | Seal obvious gaps | Start quarterly service | Re-check exclusion points |
| Documents | File closing packet | Register all warranties | Build a home-maintenance calendar |
The last 60–90 day task is the most valuable and the one most owners skip: build a recurring maintenance calendar — filter reminders every 45 days, HVAC service every spring, water-heater flush and roof check annually, pest service quarterly. Fifteen minutes setting reminders now saves you thousands over the years you own the home.
How Much Should You Budget for Year-One Maintenance?
New owners routinely under-budget upkeep, then treat every repair as a surprise. A realistic Las Vegas first-year maintenance budget looks like this:
| Item | Typical annual cost | Notes |
|---|---|---|
| HVAC tune-up + filters | $150–$300 | One-to-two services + filters every 30–60 days |
| Water heater flush | $100–$200 | DIY is near-free; annual after year one |
| Pest control (quarterly) | $400–$800 | $100–$200 per visit |
| Irrigation service + repairs | $150–$400 | Leak audit + emitters + timer |
| Roof / exterior check | $150–$350 | Higher if recoating is due |
| Repair reserve | $1,000–$2,000 | The one that breaks anyway |
| Typical year-one total | $2,000–$4,000 | Higher on older homes or big lots |
A common rule of thumb is to set aside 1% of the home's value per year for maintenance — on a $450,000 Las Vegas home that's $4,500, and the desert's demands on HVAC, roofing, and water systems make the higher end realistic. Fund a small monthly reserve and the "surprise" repairs stop feeling like emergencies.
What Do the Pros Say New Las Vegas Homeowners Skip?
In our experience representing buyers across Henderson, Summerlin, and the wider valley, the same few things get skipped — and they're the same few that turn into big bills.
The top misses: the filter cadence (twice-a-year habits from a milder climate), the water-heater flush (invisible until the tank fails early), the irrigation leak audit (silent until the water bill lands), and registering warranties (the coverage you forfeit by not filing). None of these are hard or expensive — they're just easy to defer when the boxes are still unpacked. Do them in the first 90 days and you buy yourself years of lower repair bills and a home that holds its value.

Frequently Asked Questions
How often should I change my AC filter in Las Vegas?
Every 30–60 days, not the twice-a-year cadence common in milder climates. Desert dust loads filters two to three times faster, and a clogged filter makes the AC work harder, raises your NV Energy bill, and shortens the compressor's life. During peak summer, checking monthly is smart. A pack of filters is $15–$40 — the cheapest insurance you'll buy for a $6,000+ system.
Do I really need a water softener in Las Vegas?
You don't strictly need one, but most Las Vegas homeowners are glad they installed one. Local water runs roughly 16+ grains of hardness — among the hardest in the country — which scales water heaters, clogs fixtures, and shortens appliance life. A softener runs $800–$2,500 installed and pays back in longer appliance life and fewer plumbing repairs. At minimum, flush the water heater annually and replace scaled aerators.
When is monsoon season and what should I check before it?
Roughly July through September, with microbursts that bring 60-plus mph gusts and driving rain. Before it starts, check (or have a roofer check for $150–$350) tile/flat-roof condition, flashing and seals around vents and the AC curb, stucco cracks, exterior caulk, and drainage/grading. Monsoon storms find every weak point UV has degraded all year, so a pre-season check is cheap protection.
What should a new Las Vegas homeowner do in the first week?
Re-key the locks, change every HVAC filter, locate and test the main water shutoff, label the breaker panel, test smoke and CO detectors, find the irrigation controller and valves, and deep-clean before the furniture arrives. Most of it is free or under $50, and it's the highest-leverage day you'll spend on the home. Photograph every appliance data plate for warranty registration.
How much should I budget for home maintenance in Las Vegas?
Plan on $2,000–$4,000 in year one for a typical home — HVAC service and filters, a water-heater flush, quarterly pest control, irrigation service, a roof check, and a repair reserve. A common rule is 1% of the home's value per year (about $4,500 on a $450,000 home); the desert's demands on HVAC, roofing, and water systems make the higher end realistic. Fund a small monthly reserve so repairs stop feeling like emergencies.
Does new construction still need this maintenance in the first 90 days?
Yes. A new build has fresh systems and a builder warranty, but the desert still applies: change filters on the desert cadence, register every warranty and note reporting deadlines, run the irrigation on the seasonal schedule, and set your maintenance calendar. Catching a workmanship issue in your first 90 days — while the warranty is fresh — is far easier than reporting it at year two.
What are the most common maintenance mistakes new Las Vegas owners make?
Applying mild-climate habits: changing filters twice a year, ignoring the water heater until it fails, missing a silent irrigation leak until the water bill lands, and never registering warranties. None are hard or expensive to avoid — they're just easy to defer while unpacking. Front-loading them in the first 90 days is what separates a smooth first year from a string of surprise repair bills.
