HVAC Tune-Up Service in Metro Detroit — OnPoint HVAC
Metro Detroit's Top Choice for HVAC Tune Up Services
If there is one service a Michigan homeowner can schedule to protect their home comfort investment, it's a professional HVAC tune-up. Michigan demands more from heating and cooling systems than nearly any other region — brutally cold winters, humid summers, and swing seasons that stress both your furnace and your air conditioner in the same 30-day window. A comprehensive HVAC tune-up keeps both systems operating safely, efficiently, and reliably all year long.
At OnPoint HVAC, our tune-up service isn't a cursory look-and-leave inspection. Founded by George Petrentzev, a licensed mechanical engineer based in Livonia, MI, OnPoint brings engineering-level precision to every service visit. We inspect, test, clean, and document every critical component of your heating and cooling system — and walk you through exactly what we find.
What We Check During an HVAC Tune-Up
Heating System Checks
- Heat exchanger inspection — Cracks can allow carbon monoxide to enter living spaces; one of the most safety-critical checks on any furnace service
- Burner cleaning and ignition test — Clean burners and a reliable igniter are essential for efficient combustion
- Flue and venting inspection — Confirm exhaust gases are venting properly and safely
- Gas pressure and valve check — Verify gas pressure is within manufacturer specifications
- Blower motor and belt inspection — Check motor operation, bearings, and belt tension for wear
- Air filter inspection — A clogged filter is the leading cause of furnace overheating and shutdown
- Thermostat calibration and staging test — Confirm correct communication across all heating stages
- Safety control testing — Test limit switches, pressure switches, and rollout controls
For dedicated heating service, see our furnace maintenance service.
Cooling System Checks
- Refrigerant level verification — Check charge against manufacturer specs and inspect for leaks
- Evaporator and condenser coil cleaning — Remove buildup that reduces heat transfer and efficiency
- Electrical connections inspection and tightening — Loose connections cause compressor failures and represent a fire risk
- Capacitor and contactor testing — A weak capacitor is one of the most common AC no-start failures
- Condensate drain flush — Clear blockages that cause water backup and pan overflow
- Airflow and duct check — Measure supply and return temperatures; identify restrictions
- Thermostat cooling calibration — Confirm the thermostat accurately triggers and cycles the cooling system
- Overall cooling performance test — Verify the system is cooling within design parameters
For dedicated cooling service, see our AC maintenance service.
How Often Should You Schedule a Tune-Up?
The professional recommendation is twice per year — fall before the heating season, and spring before the cooling season. This ensures both your furnace and AC are inspected at the optimal time, before peak demand.
If twice-yearly service isn't feasible, once per year is the minimum to maintain manufacturer warranty compliance.
Signs you may be overdue:
- System hasn't been professionally serviced in over 12 months
- Energy bills are rising without a change in usage habits
- System runs longer than usual to reach the set temperature
- New sounds — clicking, banging, squealing, or rattling
- Rooms are heating or cooling unevenly
- Short-cycling (turns on and off in rapid succession)
Ask about our annual HVAC maintenance plan — which includes both seasonal tune-ups plus priority service and discounts on repairs.
What Happens If We Find a Problem?
1. We document everything we find. Every observation is recorded so you have a complete picture of your system's condition.
2. We explain it clearly, without jargon. George and our technicians are engineers and communicators. If we find a failing capacitor or a cracked heat exchanger, we'll show you what it is, explain what it means, and tell you what happens if it goes unaddressed.
3. We provide a written repair quote before any work begins. Nothing proceeds without your explicit approval. You will never receive a surprise charge from OnPoint HVAC.
4. We don't pressure you. If a repair can wait, we'll tell you. If it can't — for safety or reliability reasons — we'll explain exactly why.
If repairs are needed, we offer furnace repair and AC repair services across Metro Detroit, performed by the same licensed technicians who completed your tune-up.

Frequently Asked Questions About HVAC Tune-Ups
How much does an HVAC tune-up cost in Michigan?
A single-system tune-up (furnace only or AC only) typically ranges from $80 to $150. A full dual-system tune-up generally runs $130 to $250. Homeowners who want the best long-term value should ask about our annual HVAC maintenance plan.
How long does a tune-up take?
A thorough single-system tune-up typically takes 60 to 90 minutes. A full dual-system tune-up covering both furnace and AC generally runs 90 minutes to 2.5 hours. We don't rush — every item on our checklist gets completed before we consider the visit done.
What's the difference between a furnace tune-up, an AC tune-up, and a full HVAC tune-up?
A furnace tune-up focuses exclusively on your heating system. An AC tune-up focuses on your cooling system. A full HVAC tune-up covers both in a single visit — the most cost-effective and comprehensive option. For year-round peace of mind, the full tune-up — or our annual HVAC maintenance plan — is the right choice.
