How to Know If Your AC Unit Is Ready for Another Ohio Summer

As summer approaches in Northeast Ohio, many homeowners are asking the same question: Is my AC unit ready for another season of heat and humidity? If you haven’t had your system inspected or serviced recently, now is the perfect time to ensure your AC is running efficiently and won’t leave you sweating in July.

In this guide, we’ll walk you through the key signs your AC unit may need attention, how to prepare your system for a hot Cleveland summer, and when it’s time to call in the pros at Hardin Bros HVAC.

Why You Shouldn’t Wait Until It’s Hot to Check Your AC

Ohio summers can hit hard and fast, and when the first real heat wave arrives, HVAC companies get flooded with emergency service calls. If your AC hasn’t been turned on in months, the last thing you want is to discover a problem when temperatures are climbing.

Taking a proactive approach helps you:

• • Avoid emergency breakdowns
  • Improve energy efficiency
  • Extend your system’s lifespan
  • Maintain consistent indoor comfort
  • Lower your monthly cooling costs

Signs Your Air Conditioner May Need Service

Warm or Weak Airflow

• • The system is running, but the air coming out of the vents isn’t cool—or barely blowing at all.
  • Common causes include low refrigerant, a dirty evaporator coil, or a failing compressor.

Unusual Noises or Odors

• • Rattling, buzzing, or squealing can signal loose parts, worn bearings, or motor issues.
  • Musty smells often point to mold buildup in the ducts or on the evaporator coil.
  • A burning smell could indicate electrical problems or overheating components.

Short Cycling

• • Your AC turns on and off in rapid bursts without completing a full cooling cycle.
  • This could be due to a faulty thermostat, poor airflow, or an oversized system.
  • Short cycling increases wear and tear and reduces energy efficiency.

Higher Energy Bills

• • A sudden spike in your utility bill can be a warning sign, even if your usage habits haven’t changed.
  • It may mean your system is working harder than it should to cool your home.
  • Worn parts, low refrigerant, or dirty filters can all reduce efficiency.

Your System Is Over 10 Years Old

• • Older units naturally lose efficiency over time.
  • If your system is 10 to 15 years old and needs frequent repairs, replacement may be more cost-effective.
  • New models offer improved energy efficiency, quieter operation, and better temperature control.

How to Get Your AC Ready for Summer in Ohio

Getting your air conditioner ready before the summer heat arrives can help you avoid breakdowns, save money on energy, and keep your home consistently comfortable.

Here are the most important steps to prepare your AC for the cooling season:

Replace or Clean the Air Filter

• • A clogged filter restricts airflow, forcing your system to work harder than it should.
  • Reduced airflow leads to higher energy use and poor indoor air quality.
  • Check your filter monthly and replace it every 1–3 months, depending on your household.

Clear Debris Around the Outdoor Unit

• • Your outdoor condenser needs room to release heat efficiently.
  • Remove leaves, branches, grass clippings, or anything blocking the unit.
  • Maintain at least two feet of clearance on all sides.

Check Thermostat Settings

• • Switch your thermostat from "heat" to "cool" and set it to your preferred temperature.
  • Make sure it responds quickly and accurately to temperature adjustments.
  • If you’re still using a basic thermostat, upgrading to a programmable or smart model can improve comfort and reduce energy waste.

Test the System Early

• • Turn on your air conditioner before the first hot day hits.
  • Listen for odd sounds, check that the air is cool, and make sure it’s cycling properly.
  • Spotting problems early gives you time to fix them before you need the AC full-time.

Schedule a Professional Tune-Up

An annual tune-up is the best way to ensure your system is running at peak performance. At Hardin Bros HVAC, our AC maintenance service includes:

• • Inspecting and cleaning coils
  • Checking refrigerant levels
  • Tightening electrical connections
  • Testing safety controls
  • Calibrating your thermostat for accuracy

Repair or Replace? How to Make the Right Call

If your AC is having problems, the decision often comes down to age, cost of repair, and current efficiency. Here’s a quick guide:

• • Under 10 years old with a minor issue? A repair is likely your best bet.
  • 10–15 years old and frequently breaking down? Consider replacement.
  • Repair estimate over 50% of replacement cost? It usually makes more financial sense to upgrade.

Newer systems are more energy-efficient, quieter, and compatible with smart thermostats—making them a worthwhile investment for comfort and long-term savings.
