Air Conditioning FAQ

How much does it cost to install a central air conditioner?

The cost to install a central air conditioner varies by home and system. Wisler provides a detailed written estimate after an in-home assessment — so you know the exact scope and price before work begins.

Key factors that influence price include:

  • AC size (tonnage) and efficiency rating
  • Ductwork changes, sealing, or new runs
  • Thermostat, zoning, and air quality options
  • Electrical, drain, pad/line-set, and code requirements

Flexible financing with approved credit and strong parts-and-labor warranties are available on new installations. Schedule an in-home evaluation to confirm scope and receive your exact estimate.

AC installation cost depends on your home and system needs — there’s no one-size-fits-all number. A Wisler technician will confirm pricing after an in-home assessment and provide a written, detailed estimate before any work begins.

Costs are primarily driven by system size, ductwork condition, efficiency upgrades, and add-ons like zoning or smart thermostats. Financing is available with approved credit, and all new systems include parts and labor warranties. We install and replace central AC across Southwest Virginia, including Roanoke and Rocky Mount.

If your current AC is over 10 years old or has frequent breakdowns, replacement is often more cost-effective than ongoing repairs. Newer systems also run more efficiently, which can meaningfully reduce your monthly energy bills.

Our technicians will walk you through both options with upfront pricing — so you can make the right call for your home and budget. We size and install equipment to fit local homes and Virginia building codes across Southwest Virginia.

Why is my AC running but not blowing cold air?

An AC that runs but isn’t blowing cold air usually points to one of these four issues:

  • Refrigerant leak — the most common cause; without refrigerant, the system can’t move heat out of your home
  • Drainage problem — a clogged drain line can halt cooling while the blower continues to run
  • Compressor failure — a worn compressor can’t circulate refrigerant properly
  • Condenser fan failure — a stuck outdoor fan can’t reject heat from the system

 

If the outdoor cabinet feels very hot and the fan isn’t spinning, the fan motor may be the culprit. Shut the system off to prevent further damage and call for a professional diagnostic before running it again. 24/7 emergency AC repair is available when cooling is completely lost.

Your AC can run but not cool if it has low refrigerant, a failing compressor, a broken condenser fan, drainage problems, or electrical and thermostat faults.

Try these quick checks first:

  • Set the thermostat to Cool and lower it 3–5°F
  • Replace a dirty filter
  • Clear debris from around the outdoor unit

 

If you see ice or water at the air handler, turn the system off and call immediately
If the issue continues, our NATE-certified technicians provide on-site diagnosis and 24/7 emergency service across Southwest Virginia, including Roanoke and Rocky Mount.

Intermittent warm air usually points to a refrigerant leak, drainage issue, restricted airflow from a dirty filter or coils, or a control and electrical fault. Try these steps before calling:

  • Set the thermostat to Cool and Auto
  • Replace or clean the filter
  • Clear debris from the outdoor unit
  • Look for ice on the lines or water pooling at the air handler
  • Check the AC breaker

 

If the problem continues, our NATE-certified technicians provide on-site diagnosis and 24/7 emergency AC repair in Roanoke and Rocky Mount. We won’t leave until your system is safe to run.

What is included in a typical AC tune-up?

A Wisler AC tune-up includes a complete system inspection, thorough cleaning, and targeted adjustments to improve efficiency, reliability, and equipment lifespan. During our Without Worry Comfort Check, you receive a written report card showing actual operating pressures, what we cleaned, and any adjustments made — so you see exactly how your system is running today.

What we typically do during an AC tune-up:

  • Measure system pressures and verify performance
  • Clean coils and key components
    Make necessary adjustments to optimize operation
  • Provide a detailed Without Worry Comfort Check report card
  • Offer efficiency recommendations and IAQ options like air duct sealing

 

Schedule your spring service before the first heat wave to reduce the risk of surprise breakdowns. Our NATE-certified technicians serve homes throughout the Roanoke Valley, including Salem, VA.

Most manufacturers and HVAC professionals recommend servicing your air conditioner once a year, ideally in the spring before the cooling season begins. Annual tune-ups catch small issues early, keep efficiency high, and help extend the life of the equipment.

Diamond Club members receive two annual HVAC maintenance visits — one for cooling and one for heating — as part of their membership, so seasonal service is handled automatically.

Yes. Most AC breakdowns are caused by buildup, wear, or small issues that go unnoticed until they become expensive failures. Regular tune-ups remove buildup that forces the system to work harder, catch worn parts before they fail, and verify refrigerant and electrical performance — significantly reducing the chance of a breakdown during the hottest days of the year.

Diamond Club members also benefit from our No Breakdown Comfort Guarantee — if your system breaks down out of season, we fix it free.
