Two Seasonal Tune-Ups
What Annual HVAC Maintenance Covers — Two Visits, Two Systems
A complete HVAC maintenance program is two distinct seasonal visits: a spring AC tune-up before cooling season, and a fall furnace tune-up before heating season. Each targets a different system with a different checklist and different safety priorities. Explore the full detail of each below.
Spring · Before Cooling Season
AC Tune-Up
Spring air conditioner maintenance: condenser coil cleaning, refrigerant charge verification, capacitor testing, and condensate drain clearing — so the system is ready before the first McHenry County heat wave.
- Condenser coil cleaning & cottonwood removal
- Refrigerant pressure check (R-22, R-410A, R-454B)
- Capacitor microfarad testing before failure
Fall · Before Heating Season
Furnace Tune-Up
Fall furnace maintenance: combustion analysis, heat exchanger inspection, flame sensor and igniter service — with carbon monoxide safety verification before the system runs through a McHenry County winter.
- Combustion analysis with CO measurement
- Heat exchanger inspection for cracks
- Flame sensor & igniter condition check
The Real Numbers
Why Annual HVAC Maintenance Is Worth It
Maintenance isn't an upsell — it's the cheapest way to avoid the expensive failures. The economics are straightforward, and they favor the homeowner who maintains over the one who waits for something to break.

A flame sensor cleaning caught at a tune-up versus a no-heat emergency call on the coldest night of the year
The single biggest return on maintenance is the failure that doesn't happen. A capacitor reading low at a spring tune-up is a $120 planned replacement; the same capacitor failing in July is a no-cool emergency call during a heat advisory. A flame sensor cleaned in October is a 20-minute task; the same sensor fouling in January is a no-heat call at 2 AM. Maintenance moves these from emergencies you react to into scheduled work you control — and Airwave earns no commission on any repair found, so what gets flagged is what the readings actually show.

The Difference
Annually Maintained vs. Unmaintained — What Actually Happens
The gap between a maintained system and a neglected one isn't abstract. It shows up as emergency calls, higher bills, shorter equipment life, and denied warranty claims. Here's the side-by-side.
Annually Maintained
Unmaintained
Failures caught early — a weak capacitor or fouled flame sensor is found and fixed during a scheduled visit, on your timeline.
Failures happen at the worst time — components fail under peak load, during a heat advisory or a deep-cold night, as an emergency call.
Efficiency stays near spec — clean coils and correct charge keep utility bills where they should be.
Efficiency drifts down 15–20% — dirty coils, low charge, and clogged filters quietly raise the monthly bill.
Equipment reaches full service life — often 18–22 years for a furnace, 14–18 for AC.
Equipment dies early — neglected systems frequently fail years ahead of their rated life.
Warranty stays valid — documented annual maintenance satisfies the manufacturer's requirement.
Warranty claims denied — no maintenance records can void coverage on an otherwise-covered failure.
Combustion verified safe — CO output and heat exchanger integrity confirmed every fall.
CO risk goes unchecked — a cracked heat exchanger can leak carbon monoxide undetected for a full season.

Coverage
HVAC Maintenance Across McHenry County & Adjacent Kane County
Headquartered in Lake in the Hills, Airwave provides annual maintenance throughout McHenry County and into adjacent Kane County communities, under a statewide Illinois HVAC contractor license. Each community's housing era and equipment age shape what a tune-up focuses on — and each links through to the local repair pages for that area.
Lake in the Hills
Home base. The 1990s build and 2005–2015 furnace replacement wave mean a concentration of high-efficiency equipment now in the maintenance-critical 15–20 year window.
Crystal Lake
McHenry County's largest city. Lake-effect humidity makes condensate-drain maintenance especially important on high-efficiency furnaces and AC alike.
Algonquin
Spans the McHenry-Kane county line. Western high-efficiency systems and eastern older atmospheric-vent equipment need different maintenance emphasis.
Huntley
Del Webb Sun City's synchronized 2000s equipment benefits most from consistent annual maintenance — and from the cold-priority safety checks for 55+ households.
Cary & Fox River Grove
Fox River Valley. Metra-corridor vibration and pre-war chimney liners make the fall furnace inspection particularly worthwhile in older homes.
Carpentersville
Kane County. The widest housing-age range in the area means heat-exchanger inspection during the fall tune-up matters more here than almost anywhere nearby.

HVAC Maintenance Near Me in McHenry County — What to Look For
When a McHenry County homeowner searches for HVAC maintenance, the right provider is the one who shows up with a real checklist, documents what they find in writing, and doesn't use the visit as a sales pitch. Airwave's maintenance visits produce a written inspection report every time — what was measured, what's in good condition, and what (if anything) needs attention, with no obligation to buy anything.
The no-commission structure matters most on a maintenance call. A technician paid on what they sell has every incentive to "find" problems; a technician who earns the same regardless reports only what the readings actually show. That's the difference between a tune-up that protects you and one that's really a sales appointment in disguise. Airwave's 5.0 rating across 47 verified Google reviews reflects which kind homeowners have experienced.

Licensed & Insured HVAC Maintenance
Licensed & Insured HVAC Maintenance in McHenry County
Airwave Heating and Cooling is a professional HVAC contractor headquartered in Lake in the Hills, IL. Founder and principal technician Igor Talmazan personally performs every maintenance visit.
Founder & Principal Technician
Igor Talmazan
HVAC Contractor & Founder · Airwave Heating and Cooling
Igor performs every Airwave maintenance visit personally — there's no rotating crew of subcontractors and no commission structure pushing add-on sales. A maintenance visit is the one service call where the customer's interests and a commissioned technician's interests diverge most sharply: a tech paid on what they sell is incentivized to find problems, while a tech who earns the same regardless simply reports what the instruments show. Airwave is built on the second model. Every visit produces a written inspection report documenting what was measured and what condition each component is in, so the homeowner has a record — for their own planning and for warranty compliance.
The maintenance program covers both seasonal systems: the spring AC tune-up focused on coil cleaning, refrigerant charge, and electrical components, and the fall furnace tune-up focused on combustion analysis and heat-exchanger safety. Each is documented in detail on its own page, because each is a genuinely different job with different priorities — cooling-season readiness versus heating-season combustion safety.
- Illinois HVAC Contractor License — statewide, McHenry & Kane counties
- EPA 608 Universal Certification — qualified for all refrigerant handling
- Written inspection report on every maintenance visit
- Warranty documentation to keep manufacturer coverage valid
- No commission on repairs found — reports reflect readings, not sales targets

Common Questions
HVAC Maintenance FAQ — McHenry County, IL
Answers to the plan, pricing, and scheduling questions homeowners ask most. For system-specific questions, see the AC tune-up and furnace tune-up pages.
A single seasonal tune-up typically runs $99–$159 depending on the system. The annual plan, which bundles both the spring AC tune-up and the fall furnace tune-up, runs around $219 per year — less than booking the two visits separately, and it includes priority scheduling during peak season plus a discount on any repairs found. Multi-system homes and rental-property portfolios are quoted custom by system count. All pricing is confirmed before scheduling — no membership traps or auto-enrollment. See the full plan options above.
You can book a single tune-up if you only want one system serviced — many homeowners start with just the fall furnace tune-up for the combustion-safety check, or just the spring AC tune-up before summer. But both systems benefit from annual service, and the bundled annual plan costs less than two separate visits. If your home has both gas heating and central AC, the annual plan is the most cost-effective choice. If you heat with a boiler or have no central AC, a single relevant tune-up makes more sense.
The AC tune-up belongs in spring — ideally April or May, before the first heat wave loads the system. The furnace tune-up belongs in fall — ideally September or October, before heating season and well ahead of the first deep cold. Booking each before its season means any repair found can be handled calmly rather than as an emergency, and you're not competing for a slot during the peak-demand rush. Plan members get priority scheduling during those busy windows. Off-season scheduling is fine too — a furnace can be tuned in spring if that's when you remember.
Most residential HVAC manufacturer warranties require documented annual professional maintenance to remain valid — and a denied claim on a failed compressor or heat exchanger can cost thousands. Airwave provides written inspection documentation on every visit specifically so you have the records a manufacturer may request. Keep them with your warranty paperwork. This is one of the most overlooked reasons maintenance pays for itself: a single denied warranty claim can exceed a decade of tune-up costs.
No. Igor performs every maintenance visit personally and earns no commission on repairs found — so the written report reflects what the instruments measured, not a sales target. If something genuinely needs attention, you'll see the reading that shows it and get an honest repair-vs-replace conversation with no pressure. If nothing needs attention, the report says so. This no-commission structure is the single most important thing separating a real maintenance visit from a sales appointment dressed up as one.
Yes. Landlords managing multiple McHenry County or Kane County properties, and homeowners with more than one HVAC system, are quoted custom pricing by system count with consolidated scheduling and reporting. A portfolio condition overview helps prioritize which systems need attention before another season. Call (773) 849-7379 for a quote based on your specific number of systems.
