Most AC repairs in the Raleigh area range from $150 to $650, depending on the issue. Common repairs like refrigerant recharges, capacitor replacements, or contactor failures fall on the lower end. More involved repairs — such as compressor issues or coil leaks — can run higher. We provide a clear, upfront quote before any work begins so there are never any surprises on your bill.

In the Triangle's hot, humid climate, most AC systems last 12–17 years and furnaces 15–20 years with regular maintenance. Systems that skip annual tune-ups often fail years earlier. If your system is over 12 years old and needing frequent repairs, replacement is usually the smarter financial decision — newer units are also significantly more energy-efficient.

A good rule of thumb is the "$5,000 rule": multiply the repair cost by the system's age in years. If that number exceeds $5,000, replacement is usually the better investment. Also consider: if your system is over 10 years old, uses R-22 refrigerant (now phased out), or has broken down more than once in the past two years, a new system will save you money long-term. We'll always give you an honest recommendation — not just a sale.

Yes. We offer same-day service across Raleigh, Cary, Apex, Morrisville, Wake Forest, and surrounding Triangle communities. Call us in the morning and a licensed technician can typically be at your home the same day. For urgent situations — no heat in winter or no AC in summer — we prioritize emergency dispatches across our full service area.

Most HVAC manufacturers and industry professionals recommend twice-yearly maintenance — once in spring before cooling season and once in fall before heating season. Annual tune-ups keep your system running efficiently, help catch failing parts before they cause a breakdown, and are often required to keep manufacturer warranties valid. Our maintenance plans cover both visits at a discounted rate.

An AC that runs but won't cool is one of the most common service calls we get in Raleigh summers. The most likely causes are low refrigerant (a leak), a dirty evaporator or condenser coil, a failing compressor, or a clogged air filter restricting airflow. Start by checking and replacing your air filter. If that doesn't help, the issue is almost certainly mechanical and needs a licensed technician to diagnose safely and correctly.

AC sizing isn't just square footage — it depends on your home's insulation, ceiling height, window placement, sun exposure, and duct layout. An oversized unit short-cycles and leaves your home humid; an undersized one runs constantly and can't keep up on hot days. We perform a proper Manual J load calculation on every installation to make sure you get exactly the right system — not just the easiest sell.

Yes. Every Mandolin Pros technician is fully licensed by the state of North Carolina, background-checked, and insured. We carry full liability coverage and workers' compensation on every job. You should always verify licensing before allowing any HVAC contractor into your home — in NC, you can check contractor licensing through the NC Licensing Board for General Contractors.

A standard residential HVAC replacement — swapping out an existing system with a new one — typically takes 4 to 8 hours for a single system. More complex installations (dual systems, new ductwork, or attic/crawlspace work) can take longer. In most cases, your home will have heat or AC restored the same day the installation begins. We'll walk you through the full timeline during your free quote.

First, check the basics: make sure the thermostat is set to "Heat" and above the current temperature, verify the circuit breaker hasn't tripped, and check that the air filter isn't clogged. If none of those solve it, check that your gas supply is on and the furnace's pilot light or ignitor is functioning. If you smell gas at any point, leave the home and call your gas company immediately. For everything else, call us — we offer priority dispatch for heating emergencies across the Triangle.
