What’s different in Dunn Loring

Dunn Loring cooling: 1970s heat pumps, 1990s basements, and the storms in between.

Fairfax County’s records count 732 homes in 22027, Dunn Loring’s own ZIP: 630 detached houses, 102 townhouses and not one condominium. The decade decides what’s out back. Of the 81 detached houses put up in the 1970s, 70 have no gas on the county’s books, so it’s usually a heat pump that heated the house all winter. Tysons Grove on Arden Court is the plainest case: 20 houses from 1978 and 1979, not one with gas.

From 1990 on it flips. The county lists gas at 326 of the 334 detached houses built here through 2009, every one over a full basement, where the indoor coil usually rides on the gas furnace and borrows its blower. Many are big: 57 top 4,000 square feet above ground, and a house that size often splits the cooling in two, with the bedroom air handler in the attic. Two systems book as two visits, $69 each.

The townhouses are gas over full basements too: 60 at the Regal Oaks on Journet Drive, from 1994 and 1995, where a condenser that’s still the original has cooled thirty summers, and 42 at Laing at Governors Square on Harithy Drive, from 2000 to 2002.

Vienna’s weather station, 3.6 miles west, logs about 13 days a year at 90 degrees or hotter. Wind does the local damage: the June 2012 derecho dropped three big branches across Prosperity Avenue, and a July 2017 thunderstorm put a tree on a Metro car at Dunn Loring. After a storm, look at the outdoor unit before you run it: sticks in the fan grille, flattened fins, a unit knocked off level, insulation torn off the copper lines. If anything looks wrong, switch the cooling off and call us. We’ll check it all over, and anything it needs gets a written price first.

What it costs

What an AC tune-up costs in Dunn Loring.

One price per system, $69, regularly $99. We go through it before a Northern Virginia July finds the weak part for you. Anything it turns up is priced in writing before any work, and if it can wait, we say so.

  • AC tune-up, one system$69, regularly $99
  • Furnace tune-up, one system$69, regularly $99
  • Heat pump, boiler or ductless mini split tune-up, one system$69, regularly $99
  • Comfort+ membership, a cooling maintenance visit every spring included$199 a year

A house with two systems books two tune-ups, one for each, and a heat pump or a ductless mini split is the same $69 a system. The heating side, a furnace or a boiler, gets its own tune-up in the fall at the same price.

With Comfort+ membership at $199 a year, the cooling maintenance visit comes every spring, along with a heating maintenance visit, a water heater flush with a sewer camera inspection and a dryer vent cleaning.

When to book it

When an AC tune-up is worth booking in Dunn Loring.

The heat pump never got a season off

On Arden Court or Bright Meadows Lane the outdoor unit went straight from heating to cooling, after a winter with Extreme Cold Warnings on three late January nights. Spring is the first time anybody opens it since.

Before the first hot week

A weak capacitor is a small fix on a mild day in April. Found by a July heat wave, it’s a house with no cooling.

Nobody remembers the last one

Or the sticker on the unit is from the last owners. That’s most houses, and it’s reason enough.

Questions to ask anybody who books you, us included.

  1. After a storm, will they look past the coil?

    Wind can tug on the copper lines and the wiring that feeds the outdoor unit. Ask the tech to check those too and write down what they found.

  2. What does the price cover, and is it per system?

    Ask what gets cleaned and what gets checked, and whether a second system costs extra. A number with no list behind it is hard to hold anybody to.

  3. Do they write down what they found?

    Ask for the findings in writing, with a price on anything that needs fixing and an honest word on what can wait. A tune-up you never see written down is one you take on faith.

  4. Do they find the leak before they sell refrigerant?

    An air conditioner doesn’t use up refrigerant. Low means it’s leaking somewhere, and a company that tops it up every spring is selling you the same refrigerant twice.

Quick response, Elvis was knocking my door in a couple of hours after my call to the office. He did full inspection for both HVAC units, and answered all my questions. Both systems are working well. I always have very pleasant experience with SwiftPro

Questions

AC tune-up questions from Dunn Loring.

My Dunn Loring house has no gas meter. What’s cooling it?

Most likely a heat pump: one outdoor unit that cools in summer and heats in winter, with an air handler indoors where a furnace would be. It’s the same $69 a system, and since it works all year, don’t skip its spring visit.

The power went out in a storm. Does the AC need a look?

If it came back and cools like before, it can wait for spring. If the outdoor unit hums without the fan turning, trips its breaker or blows warm air, turn it off and call. Tropical Storm Irene brought about 81,000 reported power outages to Fairfax County in August 2011, and a restart after an outage is often when a tired part gives out.

How much is an AC tune-up in Dunn Loring?

$69 per system, regularly $99, the same for a central air conditioner, a heat pump or a ductless mini split. A house with two systems books two. If the tune-up turns up a repair, you get its price in writing before any work, and you decide.

How often should an AC get a tune-up?

Once a year, in the spring, before the first heat wave. The heating side gets its own visit in the fall. The filter needs attention more often, every one to three months, and it’s the cheapest thing on the list.

Book the AC before the first hot week.

Call, or book online and pick a window. Anything the tune-up turns up gets priced in writing before anybody touches it, and if it can wait, you’ll hear that too.
