Indoor Air Quality Services

Are you experiencing unusually dry skin, excessive humidity, or stuffiness? These are common signs of poor indoor air quality. The air in your home can be up to 5 times as polluted as the air outside, making it crucial to have the right systems to keep it fresh, clean, and clear of harmful airborne particles and pathogens.

At United Air Temp, we have a variety of ways to improve your indoor air quality, including:

• Humidifier and dehumidifier installation and repair
• Dryer vent cleaning
• UV air purifier installation
• Attic fan installation and repair

Electrical Services

Is your electrical system meeting your power needs? You need a team you can trust for quick, effective, code-compliant electrical services. United Air Temp offers:

• Whole-home generator installation: It’s dangerous when the lights go out in your home, the HVAC cuts off, the refrigerator isn’t cold, and medical equipment has no power, especially during a major storm. Free yourself from concerns over power with a standby generator.
• Electric box replacement: It’s probably time for an electrical panel upgrade if you see constant circuit breaker resets, flickering lights in multiple areas, and other signs of an unreliable panel.

Local Service Coverage in Centreville

Living in Centreville means easy access to Washington D.C. via I‑66, historic charm along Braddock Road, and a quilt of diverse neighborhoods tucked behind shade trees and Civil War trails. United Air Temp technicians live and work in these communities every day, so you’ll see our red‑and‑blue vans on streets like New Braddock Road, Stone Road, and Pleasant Valley Road.

Neigh­bor­hoods and Subdivisions We Serve

• Centre Ridge & Centre Village. From the townhouses off Saint Germain Drive to single‑family homes along Ridge Water Drive, our team optimizes HVAC zoning for multi‑level living.

• Virginia Run & Sequoia Farms. Large two‑story homes often suffer from second‑floor heat rise. We balance ductwork and recommend smart thermostats to even out temperatures.

• Sully Station I & II. Many 1990s heat pumps here are past their prime. We provide efficiency‑boosting maintenance or ENERGY STAR® replacements sized for split‑foyer floorplans.

• London Towne. Historic yet compact rowhomes off Route 29 derive big benefits from ductless mini‑splits that cool without major renovations.

• Newgate, Heritage Estates, and Faircrest. Clay‑heavy soil can shift sewer lines. Our plumbers use camera inspections to spot cracks before backups occur.

• Little Rocky Run & Union Mill. Tall trees drop leaves into gutter lines, leading to basement dampness. Sump pump tune‑ups and dehumidifiers protect finished lower levels.

Beyond the 20120 & 20121 ZIP Codes

Centreville borders dozens of micro‑markets where residents still identify with the Centreville lifestyle. United Air Temp’s Fairfax County hub dispatches same‑day service to:

• Clifton (20124). Turn‑of‑the‑century farmhouses off Main Street rely on oil furnaces that we retrofit with clean‑burning heat pumps.

• Chantilly (20151). Homes near the Route 28 technology corridor demand robust surge protection for home offices—our electricians deliver.

• South Riding & Aldie (20152 & 20105). Hard well water strains water heaters. We install hybrid tanks and whole‑home filtration.

• Manassas & Bull Run (20109, 20110). Historic brick facades hide aging cast‑iron pipes. Our plumbers replace them with PEX for quiet, leak‑free flow.

• Fair Lakes & Fair Oaks (22033). Condos need compact air handlers; we specify slim cooling coils for tight utility closets.

Corridors & Landmarks

We know every shortcut from Lee Highway to Compton Road, so we reach you faster—even during afternoon backups on Route 29. Whether you live near:

Frequently Asked Questions for Centreville HVAC

Q: How often should I schedule HVAC maintenance in Centreville’s climate?

A: Twice a year—air‑conditioning tune‑up each spring and heating tune‑up each fall—keeps equipment efficient and warranty compliant.

Q: What size whole‑home generator do I need in the 20120 ZIP code?

A: Most single‑family homes require 18‑22 kW to run HVAC, refrigerators, and basic lighting. We calculate exact load during a free estimate.

Q: Can a heat pump handle Northern Virginia winters?

A: Yes. Modern dual‑fuel or cold‑climate heat pumps heat efficiently down to 5 °F. Our techs pair them with gas backup for extreme lows.

Q: Why does my second floor stay hotter than the first?

A: Warm air rises. Balancing dampers, adding a zoning system, or installing a ductless unit can even out temperatures.

Q: Is hard water common in Fairfax County?

A: Yes. Mineral content averages 120–180 ppm. A whole‑home softener protects plumbing and extends appliance life.

Q: How fast can you replace a burst water heater?

A: In most cases, the same day. We stock standard tank sizes and tankless units at our local warehouse.

Q: Do I need a permit for an electrical panel upgrade?

A: Fairfax County requires one. Our electricians pull and close all permits, so you stay fully compliant.

Q: What are signs my sewer line needs repair?

A: Frequent drain backups, soggy patches in the yard, or gurgling sounds. A camera inspection pinpoints the issue without excavation.

Q: How does a Full Service Agreement save money?

A: Members receive two annual tune‑ups, priority scheduling, and repair discounts that often offset the plan cost.

Q: Do you offer financing?

A: Yes. We partner with leading lenders to provide flexible payment options for qualified customers.
