HVAC 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 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.

How much does furnace replacement typically cost?

Furnace replacement cost varies by home and system. Wisler confirms final pricing only after an in-home assessment — so you receive a fixed-price written proposal before any work begins.

Key factors that shape total cost include:

  • Equipment type and efficiency rating (gas furnace vs. other heat sources)
  • Proper sizing from a load calculation — not the old unit’s nameplate
  • Duct, flue, or gas-line adjustments needed to meet code
  • Installation access and add-ons like thermostats or IAQ upgrades

If your heat exchanger is cracked or you’re facing repeated breakdowns, replacement is usually the safer long-term choice. Financing options are available. We replace furnaces across the Roanoke Valley, including Salem.

There is no one-size price for a 2,000 sq ft home. Final cost depends on the furnace type, efficiency rating, and the work required in your specific home. We provide upfront pricing after an in-home assessment and can offer same-day estimates.

What affects the price:

  • Fuel type and efficiency rating (AFUE)
  • Ductwork or venting changes
  • Thermostat, zoning, and code upgrades

Financing is available through GoodLeap, including some 0% no-interest options. We install and replace heating systems across Roanoke and Martinsville.

A complete Wisler furnace replacement includes:

  • In-home assessment with upfront written pricing
  • Removal and haul-away of the old unit
  • Installation of a new energy-efficient furnace
  • Connection to existing ductwork
  • System startup with testing and safety checks
  • Thermostat options and setup
  • Full jobsite cleanup

Our NATE-certified technicians arrive in fully stocked vehicles and provide 24/7 emergency support. Financing through GoodLeap is available, including some 0% offers. Service available across Roanoke and Rocky Mount.

What should I do if my heater is not working?

Start with a few quick checks before calling. If the system still won’t run or smells odd after these steps, stop and call us for 24/7 emergency heating service.

  • Set the thermostat to Heat and raise it 3–5 degrees above room temperature
  • Replace thermostat batteries
  • Check the breaker and furnace or air handler power switch
  • Make sure the filter isn’t clogged — a blocked filter can shut the system down
  • For heat pumps, clear any snow or debris from the outdoor unit

We’ve served Roanoke and nearby areas since 1986 and provide 24/7 emergency heating service when you need it most.

Most no-heat calls start with issues you can check quickly. Watch for uneven rooms, higher energy bills, odd odors, or a system that won’t reach the set temperature. Common causes include:

  • A dirty air filter restricting airflow — replace it to restore heat flow
  • Thermostat not set to Heat or set below room temperature
  • A tripped breaker or a furnace or air handler switch turned off
  • Supply or return vents that are blocked or closed

If basic checks don’t resolve it, our technicians provide detailed diagnostics with a written report and 24/7 emergency service across Roanoke, Vinton, Moneta, and nearby areas.

Heating repair cost varies by the problem and parts involved. Wisler confirms final pricing only after an on-site diagnosis — we offer free estimates on heater repairs and provide a firm, upfront written quote before any work begins.

Key factors that change the price include:

  • The specific failed component and its availability
  • System type and age affecting parts and labor
  • Equipment accessibility and any needed duct or electrical corrections
  • After-hours emergency service versus scheduled daytime repairs

If your system is older or needs multiple major components, we’ll compare repair vs. replacement so you can choose confidently.

How much does yearly furnace maintenance cost?

Yearly furnace maintenance with Wisler is available two ways:

  • $99 Furnace Tune-Up — a single visit covering a full inspection, cleaning, and performance check
  • Diamond Club Membership ($24/month) — includes up to three Without Worry Comfort Checks per year, with furnace maintenance scheduled before winter

Diamond Club members get the most value, with heating, cooling, plumbing, and electrical visits all covered under one low monthly rate. Service available across Roanoke, Martinsville, and nearby communities.

A Wisler furnace tune-up covers a complete system inspection, cleaning, and performance adjustments to improve reliability and efficiency heading into winter. As part of our Without Worry Comfort Check, you receive a written report card showing what we inspected, what we cleaned, and how the system is actually performing — not just that it “looks fine.”

Our NATE-certified technicians arrive prepared, explain what was done and why, and flag any early warning signs before they become costly breakdowns. Schedule your fall service before the first cold snap.

Annual furnace service is recommended, ideally in the fall before the heating season begins. A yearly tune-up catches wear, cleans components that reduce efficiency, and verifies safety — including checks for carbon monoxide risks from cracked heat exchangers.

Diamond Club members receive scheduled furnace maintenance automatically as part of their membership, so there’s no need to remember to call each year.
