How to Complete Both Annual HVAC Services
Your first year is the only time you get to set the cadence for every future HVAC visit. Book one contractor in the spring for the AC tune-up and the exact same company in the fall for heating service. This builds a continuous service history, catches warranty-eligible repairs before year-one windows close, and gives you the baseline measurements future technicians will compare against for the next decade.

Timing the Two Visits Across Your First Year
The cadence is simple once you set it in year one. Spring AC tune-ups run March-May and fall heating tune-ups run September-October. Miss either window and you pay emergency rates or wait weeks for an appointment.
Book the spring AC tune-up in early March
Call when outdoor temperatures are still in the 40s. Contractors have open calendars before cooling demand spikes in May. A first-year visit includes refrigerant charge check, coil cleaning, capacitor test, contactor inspection, drain line flush, and blower amp draw measurement. Insist the technician write down every measurement — these are your baseline numbers.
Book the fall heating tune-up in early September
Same logic. Call before the first frost when contractors still have full availability. A gas furnace visit includes combustion analysis, heat exchanger inspection, burner cleaning, flame sensor cleaning, safety control testing, and gas pressure verification. For heat pumps, the fall visit checks reversing valve operation and defrost cycle.
Keep both visits with the same contractor
A technician who returns six months later with their own notes catches trend-based problems a new company would miss entirely. They also stop re-selling repairs you already had done. This single decision — one contractor, both visits — is why year-one HVAC planning pays dividends for the life of the system.
Establishing Your System Age Baseline in Year One
Most new homeowners have no idea how old their HVAC equipment actually is. Year-one service is your chance to record it permanently and project remaining life.
What to Capture During the Year-One Visits
- Manufacture date from nameplate: Decode the serial number — most manufacturers embed a week and year code. A 2011 install is already 15 years old and approaching end of life. Photograph the nameplate so you never lose it.
- Install date vs manufacture date: Check permit records at the county for the actual installation year. A unit manufactured in 2015 could have been installed in 2017 if it sat in a warehouse. The permit date governs warranty calculations.
- Refrigerant type: R-22 systems are obsolete — refrigerant costs $150-200 per pound and replacement is mandatory. R-410A systems are current but will see a 2025-onward phase-down. Document what you have so you plan ahead.
- Expected remaining life: AC systems average 12-17 years, furnaces 15-25 years, heat pumps 10-15 years. Year one tells you where you sit on that curve and when to start budgeting for replacement.
- Tonnage and BTU ratings: Oversized or undersized equipment explains comfort complaints and high bills. Record the nameplate ratings so you can evaluate sizing before any future replacement.
Catching Warranty-Eligible Repairs Before They Expire
Year one is often your last chance to catch covered failures from prior-owner warranties. Transferable warranties sometimes have 30-60 day transfer windows at closing, and manufacturer parts warranties often expire at 10 years from install.
Check the original manufacturer warranty status
Call the manufacturer with the serial numbers from both spring and fall visits. They will tell you exactly what coverage remains. Heat exchangers often have 20-year or lifetime warranties. Compressors typically have 10-year parts coverage. A cracked heat exchanger caught in year one could be a $0 part replacement instead of a $2,500 repair.
Verify transfer registration if required
Some warranties only transfer to a new homeowner if you register with the manufacturer within 30-90 days of closing. If you missed the window, call anyway — manufacturers sometimes extend grace for legitimate first-year owners. Document everything in writing.
Flag marginal components before year two
A capacitor reading 6% below spec, a contactor with minor pitting, or a blower motor drawing 10% above nameplate are all pre-failure signs. Ask your contractor to document borderline measurements. If any fail in year two, you have first-year evidence they were already degrading during the warranty window.
Deciding on a Maintenance Plan After Year One
Every contractor pitches a maintenance plan. After both visits, you have the data to decide whether it pays off for your specific home and system age.
- Standalone tune-up math: Two independent visits run $300-800 per year depending on region and whether the contractor bundles filter replacement, coil cleaning, and combustion analysis separately.
- Maintenance plan math: Plans typically cost $150-300 per year and include both seasonal visits, a 10-15% discount on repairs, waived diagnostic fees ($75-150 each), and priority scheduling during peak demand.
- Break-even: On a system under 10 years old with no active problems, the plan roughly ties the standalone cost. On a system over 10 years old or one with any flagged marginal components, one avoided emergency diagnostic fee typically pays for the plan by itself.
- Red flags in plan contracts: Auto-renewal clauses, cancellation penalties, inflated "plan-only" repair prices that offset the discount, and requirements to use only their parts. Read the fine print before signing.
Pro Tips
- •Get the full checklist in writing after each visit: A legitimate tune-up includes 20+ measurements. If the invoice just says "tune-up performed" with no data, you paid for an oil change without the inspection. Insist on a line-by-line report with numeric values.
- •Photograph every sticker and nameplate yourself: Do not rely on the contractor's report. Take your own photos during the visit. Serial numbers, refrigerant weight labels, and efficiency ratings become your permanent home binder record.
- •Ask about the system's remaining life directly: A technician who has seen your nameplate and run the diagnostics can give you a ballpark — "you have 3-5 years on the AC and 8-10 on the furnace." Year one is when to start the replacement savings fund.
- •Skip the plan if your system is brand new and under manufacturer warranty: Builder warranties often cover the first 1-2 years in full. Paying a maintenance plan on top is duplicate coverage for the first year and a half.
Frequently Asked Questions
Should I use the same HVAC contractor for both visits in my first year?
Yes. The single biggest year-one benefit is service-history continuity. When one technician returns for the fall visit and sees their own spring notes, they catch trend-based issues (rising amp draw, declining refrigerant charge, weakening capacitor) that a different company would miss. They also stop upselling repairs you already had done six months earlier.
How much should both annual HVAC services cost together?
Budget $150-400 per visit for standalone tune-ups, so $300-800 per year for both. A maintenance plan bundles both for $150-300 per year and typically includes a 10-15% repair discount, waived diagnostic fees, and priority emergency service. If your system is over 10 years old, the plan usually pays off in one avoided emergency call.
What does a first-year HVAC tune-up reveal that later years don't?
Year one captures baseline measurements: supply/return temperature split, static pressure, refrigerant superheat and subcool, blower amp draw, and capacitor microfarad rating. In year two, your technician compares against these numbers to spot slow declines. Without the baseline, you only see problems once the system fails outright.
