Heat builds, humidity climbs, and comfort evaporates. When your AC falters, you feel it in every room, on every bill, and in every late-night toss and turn. You want a local team that answers the phone, shows up fast, speaks clearly, and fixes the root cause—not just the symptom. SWVA Mechanical delivers that experience across Lebanon, VA and nearby communities with expert AC Repair Lebanon, VA that targets problems at their source. Our technicians carry the parts most systems need, follow a proven diagnostic path, and show you data that confirms the fix. You call once. We bring tools, parts, and a plan. We restore comfort today and help you keep it, even when summer hits hard.

Why Homeowners Choose Our Trusted Local Technicians

We invest in training. Our technicians complete hands-on labs, factory modules, and safety refreshers throughout the year. They handle legacy single-stage equipment and modern inverter systems with equal confidence.

We communicate in plain language. We explain findings, show readings, and outline options before we start. You decide, we execute, and you see exactly what you paid for.

We protect your space. We use shoe covers, drop cloths, and tidy workflows. We leave every work area cleaner than we found it.

We stock our vehicles to finish jobs fast. We carry capacitors, contactors, motors, drain components, ignition and control boards for common models, coil cleaners, brazing supplies, and leak-detection tools. That preparation cuts downtime and eliminates unnecessary return trips.

We stand behind the work. We write parts and labor warranties on your invoice and store baseline readings for future checkups. When you schedule maintenance later, we compare today’s numbers to past numbers and catch drift before it becomes a breakdown.

We live here. Our team shops on the same streets and cheers at the same fields. We support local programs and treat every visit like a neighborly promise.

Recognize Problems Early and Cut Repair Costs

You can spot trouble early and save money when you act quickly. Watch for these warning signs and call SWVA Mechanical for AC Repair Lebanon, VA before stress spreads through the system.

• Warm air or weak airflow at supply registers
• Short cycling or nonstop running
• Ice on refrigerant lines or the indoor coil
• Water near the air handler or damp ceiling registers
• New noises: buzzing, rattling, grinding, squealing
• Musty odors or burning smells at startup
• Rooms that ignore the setpoint and swing hot or cold
• Utility bills that jump when weather stays similar

Run three fast checks while you wait:

1. Set the thermostat to Cool and Auto, then drop the setpoint below room temperature. Replace batteries if the display looks dim or dead.
2. Pull the filter and check for collapse or heavy dirt. Install a clean filter that fits the system’s recommended MERV.
3. Check the breaker labeled for the air handler and the outdoor unit. If one tripped, reset it once. If it trips again, stop and call.

If the system still struggles, book a visit. We’ll find the cause and stop the cascade of damage that drives costs up later.

Our Diagnostic Process Finds the Real Cause

Guesses waste money. Data solves problems. We follow a repeatable, thorough process on every AC Repair Lebanon, VA visit.

1. Listen and Inspect
   You describe the symptoms, the timeline, and any previous work. We confirm model numbers, inspect the condenser and air handler, check the condensate drain, and evaluate duct access.
2. Electrical Health
   We test capacitors, contactors, relays, fuses, and control circuits under load. We record line voltage, low-voltage stability, inrush current, and running amps. Those numbers reveal stress that visual checks miss.
3. Refrigerant Performance
   We connect gauges, read pressures, and calculate superheat and subcooling. We measure the temperature split between return and supply. We confirm coil conditions and look for frost, oil stains, or UV dye from past leaks.
4. Airflow and Ducts
   We measure static pressure, confirm blower settings, and inspect for crushed runs, loose connections, or open seams. We balance registers and identify rooms that need damper adjustments.
5. Controls and Sensors
   We calibrate the thermostat, validate sensor inputs, and verify staging or inverter logic. We test float switches and safeties that protect against water damage.
6. Explain, Price, and Repair
   We show readings, translate them into plain language, and propose good/better/best solutions when choices exist. You select the path; we perform the work; we document final readings so you can see the improvement.

That sequence removes doubt and delivers lasting results.

Fix Common AC Failures with Proven Methods

Capacitors and Contactors

Weak starts hammer compressors and fans. We test capacitance against nameplate ratings, match replacements precisely, torque connections, and verify smooth starts with healthy inrush and running amps. We address pitted contactors and heat-scorched terminals before they burn motors or trip breakers.

Refrigerant Leaks

Low charge always points to a leak. We find the leak with electronic detection, nitrogen pressure testing, or UV dye. We repair copper joints with clean brazes, replace corroded coils or line sections when necessary, evacuate the system to a deep vacuum, weigh in the correct charge, and prove performance with superheat, subcooling, and temperature split.

Dirty Coils

Dirt blocks heat transfer and drives pressures out of range. We clean the condenser and indoor coil with coil-safe chemicals, rinse thoroughly, straighten fins, and retest. We monitor head pressure and temperature split to confirm gains.

Blower and Condenser Fan Motors

Failing motors reduce airflow, overheat, and trigger frequent lockouts. We test windings, bearings, and module health. We match replacement HP and RPM (or ECM profile), set blower speeds to meet target static pressure, and balance registers for even comfort.

Thermostats and Controls

Poor placement and bad calibration create comfort complaints. We relocate thermostats away from sunlight or supply drafts, fix low-voltage shorts, and program smart controls that optimize schedules and humidity.

Condensate Drains

Clogs cause leaks and forced shutdowns. We clear the line, rebuild traps when design flaws exist, treat the drain for growth, and install a float safety switch that protects ceilings, floors, and equipment.

Duct Problems

Leaky trunks and crushed branches starve rooms of air. We seal with mastic, remove blockages, add balancing dampers, and correct returns that choke the system. Balanced airflow reduces runtimes and noise.

Hard-Start and Compressor Decisions

Aging compressors struggle to start and pull heavy current. We measure inrush, analyze winding health, and install a hard-start kit when it helps. If the compressor fails mechanically or loses efficiency severely, we share clear repair-versus-replacement math so you can choose the best path for comfort and cost.

Three Brief Case Studies

Late-Night No-Cool – West Side Home
The homeowner reported warm air and a loud hum outside. We tested the dual capacitor, found an out-of-spec reading, and replaced it with a correctly rated unit. We rinsed the condenser coil, confirmed the charge by subcooling, and restored a 19°F temperature split. The family slept cool that night and saw a lower runtime the next week.

Restaurant Lunch Rush – Downtown
The manager spotted a damp ceiling register and rising humidity. We cleared a clogged condensate line, rebuilt the trap, installed a float switch, and cleaned the indoor coil. We balanced airflow and adjusted setpoints for the dining room. The leak stopped, humidity dropped, and lunch service continued without closing.

Office Hot/Cold Complaints – Business Park
The office staff complained about a freezing lobby and a hot conference room. We sealed duct leaks, added balancing dampers, and relocated a poorly placed thermostat away from a sunlit wall. The system reached the setpoint without long cycles, and noise dropped across the building.
