Signs You Need a New AC

Replacing your AC can feel like a big decision, but delaying it can lead to higher costs and greater discomfort. Here are a few clear indicators that it may be time for a new air conditioner:
  • High Energy Bills: Older AC systems are less efficient and often struggle to keep your home cool, driving up your energy costs. A noticeable increase in your utility bills could be a sign your system is failing.
  • Outdated Refrigerants: Older systems use refrigerants that are no longer available or environmentally friendly. If your system requires a refrigerant leak repair, finding a solution may no longer be feasible or affordable.
  • Constant Operation: If your AC runs nonstop even during moderate weather, it may no longer be capable of maintaining your home’s comfort level.
  • Frequent Repairs: If your AC requires repairs every season, it’s a clear sign the system is deteriorating. Frequent issues often lead to an eventual system failure.
  • Age of the Unit: An AC over 15 years old may be nearing the end of its life. Replacing an old unit can lead to significant energy savings, sometimes between 20-40%.

If you notice any of these signs, it’s best to address the issue before it becomes a bigger problem. Contact us at 571.346.3940 for a free quote today!

AC Replacement and Installation FAQs

Will Installing an AC Unit Add Value to My Home?

Adding or upgrading an air conditioning unit can increase your home’s value by up to 10%, depending on the efficiency and features of the system. In some areas, not having air conditioning may make a home less attractive to buyers, so installing a new AC could be a valuable investment, especially if you’re planning to sell soon.

Not necessarily. Many people assume that a larger air conditioner will perform better, but this isn’t always the case. An oversized unit may cool your home faster, but it will likely consume more electricity and fail to properly manage humidity levels. In fact, longer cooling cycles are generally more efficient and better for both your home and your energy costs.

Some homeowners in Reston consider replacing just the outdoor unit of their air conditioner to cut costs. However, this can lead to frequent repairs, higher energy bills, and reduced efficiency. While it may seem like a way to save money initially, replacing both the outdoor and indoor units together ensures better performance and long-term savings.

Getting multiple quotes for AC replacement in Sterling or Reston is a good way to ensure you’re getting a fair price. But don’t just look at the numbers—make sure to compare the specifics. Does the other company offer a comparable warranty or unit? How experienced are they? These factors are important to consider. Also, check out our financing options and special offers for the best deals.

Installing your own air conditioner in Reston is not recommended. The process involves complex electrical and refrigerant work that can be dangerous if not done correctly. Unless you have the proper certifications, it’s safest and most effective to rely on the experienced HVAC professionals at Dave’s Heating and Air Conditioning for your AC replacement needs.

Once your air conditioner reaches 10 to 15 years old, it’s a good idea to budget for a replacement. HVAC prices tend to be lower in the months leading up to summer. For the best deals and availability, plan your AC replacement during the transition from winter to spring, typically between February and April. During this time, HVAC contractors are often less busy and may offer special financing options.

Buying a new air conditioner is a big decision, and it’s best to consult a licensed HVAC contractor to determine the right system for your home. They’ll measure your space and recommend a suitable unit. However, here are some general tips:

  • Choose a trusted brand for your AC unit.
  • If you plan to stay in your home, opt for a more energy-efficient model to save on future costs.
  • Be sure to inquire about warranties on the unit.

The right location for your new air conditioner in Reston depends on your home’s unique features. Local codes, square footage, drafts, and HOA rules can all impact the installation. Here are some general tips to keep in mind:

  • Shady Areas: Install the unit on the north or east side of your home, or under a tree, to keep it cool and improve performance.
  • Keep Pets Away: To prevent pets from damaging the unit, avoid placing it where they can reach it. If needed, use fencing or shrubs to protect it.
  • Grass or Mulch Surroundings: If possible, install the unit in a grassy or mulched area rather than on concrete or PVC slabs, which can cause heat buildup and reduce efficiency.

    For the best placement, it’s always best to consult with the AC experts at Dave’s.
Installing a new air conditioner typically takes four to six hours. The process could take longer if extra tasks, like flushing the refrigerant lines or installing brackets, are required. For a more accurate timeline, ask our technician—they’ll be happy to clarify the expected duration based on your specific installation.

With the right ductwork and modifications, central air can be added to almost any home in Reston. Before moving forward with a contractor, call 571.346.3940 to discuss the installation process. We’ll also help you evaluate alternatives like ductless mini-splits, heat pumps, whole house fans, and evaporative coolers, which may provide similar results at a lower cost.
