How much does AC repair cost in Livonia, MI?

AC repair costs vary based on what failed and what parts are required. Common repairs such as capacitor replacement typically run $150–$350. Refrigerant leak repairs, coil cleaning, and blower motor replacements range higher depending on parts and labor time. We provide a firm estimate before any work begins — no guessing on your end. Request a service call to get accurate pricing for your specific situation.

My AC is running but not cooling — what is wrong?

The most common causes are low refrigerant charge from a leak, a dirty or restricted evaporator coil, or a failing compressor struggling under load. A frozen evaporator coil — which typically thaws overnight and then refreezes when the system runs again — is another frequent culprit. Any of these require a proper diagnostic visit to identify the root cause. Call (248) 331-8090) to schedule a same-day or next-day diagnostic.

Should I repair or replace my aging AC in Livonia?

The general guideline is that a repair costing more than 50% of replacement cost on a system older than 10–12 years is a strong signal to replace. However, the right answer depends on the specific failure, the overall condition of the rest of the system, and whether there are efficiency gains available from newer equipment. OnPoint HVAC gives you both numbers — repair cost and replacement cost — with an honest recommendation. There is no pressure either way.

AC Repair Livonia MI | OnPoint HVAC

OnPoint HVAC is not just a contractor that serves Livonia — we are a Livonia company. Our shop is on Joy Road, our technicians live here, and we have repaired air conditioners in virtually every neighborhood in this city. When your AC stops cooling on a July afternoon in Livonia, you are not calling a dispatcher in a distant call center who will fit you into a regional schedule — you are calling your neighbors, and we show up fast.

We are a licensed, family-owned HVAC contractor founded and led by George Petrentzev, a licensed mechanical engineer. That engineering background shapes how we handle every AC repair in Livonia: diagnosis before parts, root cause before band-aids, and honest recommendations whether the answer is a repair or a replacement.

Metro Detroit summers are humid and increasingly hot, and Livonia's older housing stock — much of it built in the 1960s and 1970s — means many homeowners are running aging central air systems that need more than routine maintenance. These are the AC problems our Livonia technicians encounter most often:

Capacitor Failure Capacitors start and run the compressor and fan motors. They are one of the most common AC failures in Michigan, particularly during the first heat waves of summer when systems that sat dormant all winter are suddenly asked to run at full load. A failed capacitor usually means the system hums but does not start — a straightforward repair when diagnosed correctly.

Refrigerant Loss A refrigerant leak causes the system to lose cooling capacity gradually, often presenting as the AC running constantly without reaching the set temperature, or ice forming on the refrigerant lines or evaporator coil. We locate and repair the leak before recharging — adding refrigerant to a leaking system without fixing the source is a temporary measure that leaves the underlying problem in place.

Frozen Evaporator Coil A frozen coil is usually a symptom of another problem — low refrigerant charge, restricted airflow from a dirty filter or blocked return, or a failing blower motor. We diagnose what caused the freeze, not just thaw the coil and send you a bill.

Compressor Issues The compressor is the heart of your AC system. Compressor failures range from electrical faults and capacitor-related problems to internal mechanical failures. We evaluate the age and overall condition of the system before recommending a compressor repair or replacement, because in some cases a compressor failure in an aging system is the right trigger for a full equipment upgrade.

Condenser Fan Motor Failure The outdoor condenser fan pulls air through the condenser coil to reject heat. A failed fan motor causes the system to overheat and shut down on high pressure. Left unaddressed, repeated high-pressure shutoffs cause compressor damage.

Thermostat and Control Issues Not every AC problem is mechanical. Thermostat calibration errors, wiring faults, and control board failures can cause symptoms that look like equipment failures. We trace the full control circuit before condemning mechanical components.

Diagnosis First — Always. We arrive at your Livonia home with diagnostic equipment and evaluate the full system before recommending any repair. We check refrigerant pressure, electrical supply and component function, airflow, thermostat operation, and overall system condition. This takes more time than swapping the obvious failed part, and it is what prevents a return call two weeks later for the next failure the first tech missed.

Clear Estimate Before Any Work. You hear a plain-language explanation of what failed, why, and what it costs to fix — before we touch anything. No authorization surprises on the invoice.

Repair and Run-Test. After completing the repair, we run the system through a full operational cycle, measuring supply air temperature, checking amp draws on the compressor and fan motors, and confirming the system is maintaining the target temperature before we leave.

Being engineer-led means something specific in how we handle AC repairs. George Petrentzev's background as a licensed mechanical engineer means our technicians are trained to look at system performance holistically — refrigerant charge is verified against manufacturer specs and actual operating conditions, not estimated; airflow issues are traced to their source; and electrical problems are diagnosed with instruments, not guesses.

It also means we tell you the truth about your system's condition. If your 18-year-old AC has a failed compressor and the rest of the system is showing its age, we will tell you what a repair costs and what a replacement costs, and we will give you our honest assessment of which investment makes more sense for your home. That is the recommendation George would want for his own home, and it is what we give every Livonia customer.
