Signs That It’s Time for a New AC
We understand the hesitation to replace your AC—it’s costly and inconvenient, and not something most people in Reston plan for. It’s easy to be tempted to stretch the life of your old unit, but eventually, a replacement is inevitable. Here are a few signs that your current AC is nearing the end of its service life:
- Skyrocketing Utility Bills: Older AC systems in Reston are less efficient and struggle to cool effectively. Over time, they can become much more expensive to run. If you’ve noticed a sudden increase in energy costs, it could signal that a major breakdown is on the way.
- Old Refrigerants: Older refrigerants harm the environment and have been phased out in favor of newer, eco-friendly alternatives. While your older AC may still work, replacing the refrigerant for a leak may no longer be feasible or cost-effective, and in some cases, it may not even be available.
- The Unit Never Shuts Off: While it’s normal for ACs to run longer during hot weather, an old unit that constantly runs—even when it’s not that hot—is a sign it’s struggling to meet target temperatures. If this happens, it’s a clear indication that maintenance or replacement is needed.
- We’re on a First-Name Basis: If you’re calling for repairs multiple times a season, it might be time to replace your AC. Just like dominoes, old components fail in sequence, eventually leading to a total system breakdown. Since quotes are free, why not get a quote for a new air conditioner installation in Herndon or Reston?
- Age: The average air conditioner can last over 15 years with proper maintenance. However, if your unit is nearing that age, it’s often more cost-effective to replace it. The U.S. Department of Energy estimates that replacing an old unit can save between 20 and 40 percent on energy bills.
If you notice any of these symptoms, don’t wait—call us at 571.346.3940 right away! Addressing the issue now can save you from a costly AC repair in Reston and might allow you to extend the life of your current unit. However, delaying could lead to bigger, more expensive problems in the future.

AC Replacement and Installation FAQs
Will Adding an AC Unit Increase the Value of My Home?
It usually does! Replacing or installing a new air conditioner in Reston can increase your home’s value by up to 10 percent. The added value depends on the unit’s efficiency and features. In some areas, a home without a cooling system may not even be sellable. So, if you plan to sell soon, investing in a new air conditioner could be a smart move.
Shouldn't I Buy the Biggest Air Conditioner Possible?
Many homeowners believe bigger is better when it comes to air conditioning in Reston, but that’s not the case. An oversized AC may cool your home faster, but it will consume more electricity and struggle to remove humidity effectively. While your AC unit in Reston may run longer, longer cycles are actually more efficient for both your wallet and your home than shorter ones.
Can I Save Money by Replacing Only My Outdoor Unit?
Air conditioners have both interior and exterior components, and some homeowners in Reston believe replacing just one to cut AC repair and installation costs is a good idea. However, this approach can lead to frequent repairs, higher energy bills, and reduced efficiency. While the initial cost may seem high, replacing both parts of your cooling system will ultimately save you money in the long run.
How Do I Know Your AC Installation Quote Is Fair?
We recommend getting multiple quotes for AC replacement in Sterling or Reston to ensure you get a fair deal. However, be sure to compare like-for-like. Does the other company offer a warranty as good as ours? Is the unit comparable? How long have they been in business? These factors should influence your decision. Be sure to check out our financing and special offers pages to see what deals we’re currently offering.
Can I Install the New Air Conditioner Myself?
While you might be tempted to repair or install your own air conditioner in Reston, it’s not recommended. Properly sizing, installing, and testing an air conditioner involves handling complex electronic and chemical components, and tampering with these can be dangerous. Unless you have the proper certifications, it’s best to leave AC replacement in Reston to the HVAC experts at Dave’s Heating and Air Conditioning.
I Know I Need a New AC in Reston. What's the Best Time to Get a Replacement?
As mentioned earlier, once your air conditioner reaches 10 to 15 years old, it’s time to start budgeting for a replacement. Like many products, HVAC pricing follows a cyclical pattern. For better deals on AC units, start shopping early before summer heat kicks in. As winter transitions into spring, many local HVAC contractors experience slower schedules, making it easier to book appointments. This period also often comes with special financing offers. For Virginia, this window typically falls between February and April.
What AC Unit is Best for My Home?
Shopping for shoes online is one thing, but purchasing a new AC unit in Reston is a different process. Always get a quote from a licensed HVAC contractor, as they have the expertise to accurately measure your home and determine the best equipment for your needs. However, there are a few general tips we recommend to everyone:
- Ensure the contractor installs equipment from a trusted brand
- If you’re not selling your home, opt for a more energy-efficient model
- Inquire about included warranties
What's the Best Place to Install My New AC?
There’s no one-size-fits-all answer to this question, as every home in Reston is unique. Factors like local codes, square footage, building materials, drafts, wall direction, and even homeowner association rules can influence where the air conditioner should be installed. While there’s no secret formula, here are some general guidelines:
- Shady Areas: In Reston, keeping the AC unit cool helps its performance. Ideally, place it on the north or east side of your home, or under a leafy tree if possible.
- Away from Pets: Animals like to pee on or chew air conditioners, which can damage the unit and harm your pets. Over time, urine can also damage fan blades. If there’s no sheltered area, consider surrounding it with a fence or shrubs to keep pets away.
- Grass or Mulch Areas: Most air conditioners are placed on concrete or PVC slabs, which can radiate heat back into the unit, making it work harder. If there’s no grass or mulch around the unit, we might suggest adding some.
How Long Does It Take to Install a New AC Unit?
A standard AC replacement and installation in Reston usually takes between four and six hours. The time may be longer if additional tasks, like flushing the line or adding brackets, are required. For a more precise estimate of how long the installation will take, feel free to ask our technician—they’ll be happy to explain the process.
Can My Home Have Central Air?
If you’re open to investing in ductwork and design modifications, any home in Reston can benefit from central air. But before you call your local building contractor, give 571.346.3940 a call. We’ll guide you through the installation process and help you explore alternative cooling options. Solutions like ductless mini-splits, whole house fans, evaporative coolers, and heat pumps may offer similar benefits at a lower upfront cost.
