Furnace Tune-Up & HVAC Maintenance in Livonia, MI
Livonia's Choice for Furnace Tune-Ups & HVAC Maintenance
If there's one service a Michigan homeowner should have on the calendar every year, it's a professional furnace tuneup. Michigan asks more of a heating and cooling system than almost any other region — brutal winters, humid summers, and swing seasons that stress your furnace and your air conditioner within the same 30-day window. A thorough tune-up keeps both systems running safely, efficiently, and reliably all year.
At OnPoint HVAC, a tune-up 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, in plain language
What We Check During a Furnace Tune-Up
Heating System Checks
• Heat exchanger inspection — cracks can allow carbon monoxide into 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

What We Check During an AC Tune-Up
• 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.
What Homeowners Say About Our Tune-Ups
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?
• We document everything we find. Every observation is recorded so you have a complete picture of your system's condition.
• 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.
• 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.
• 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 Livonia and the surrounding area, performed by the same licensed technicians who completed your tune-up.

Furnace & AC Tune-Up Pricing FAQ
How much does a furnace tune-up cost in Livonia, MI?
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.
How often should I get a furnace tune-up? (new)
Twice per year is the professional recommendation: fall before heating season and spring before cooling season. Once
per year is the minimum to maintain most manufacturer warranty requirements.
Do I need a furnace tune-up if my system seems to be working fine? (new)
Yes. Many furnace problems, including cracked heat exchangers and weakening safety controls, produce no noticeable
symptoms until they fail. A routine tune-up catches these issues while they're still inexpensive and safe to address
