HVAC Installation & Replacement
Your heating and cooling system is one of the most important components of your home, especially in Alexandria and the surrounding Northern Virginia area, where summer temperatures can soar above 80° or even 90°. Without a reliable air conditioner, your home can quickly become uncomfortable.
If your AC unit is 10–15 years old, frequently breaks down, or is no longer under warranty, it may be time for a complete HVAC replacement. This involves removing your old system and installing a new, energy-efficient heating and cooling system designed specifically for your home.
At Alexandria Heating & Cooling, we take a different approach. Rather than simply swapping out your old unit, we evaluate your home’s ductwork, airflow requirements, and proper system sizing to ensure your new HVAC system delivers maximum comfort and efficiency.
As your trusted local HVAC experts, we provide a thorough assessment of your current system, explain your options clearly, and recommend the best solution based on your budget, comfort needs, and home layout.
Ready to upgrade your home’s comfort? We offer free, no-obligation AC replacement estimates for both new and existing customers. Contact us today to schedule your HVAC installation consultation in Alexandria and the surrounding Northern Virginia communities.

Types of Air Conditioning and Heating Systems We Install
Homes throughout Alexandria and the surrounding Northern Virginia area feature a wide range of HVAC systems. At Alexandria Heating & Cooling, we have the knowledge and experience to install or replace virtually any type of heating and cooling system in the region. Whether you’re upgrading an older unit or installing a system in a new home, we’re ready to handle the job.
Here are the most common HVAC systems we install and replace throughout Northern Virginia:
Heat Pump Split Systems
One of the most common types of air conditioning systems in Northern Virginia is the Heat Pump Split System. These systems include an outdoor heat pump condenser and an indoor air handler. Shown here is a Trane XV20 Variable Speed Heat Pump Split System paired with the Tam9 Hyperion Air Handler. For improved indoor air quality, it can also be combined with high-efficiency filtration systems, such as the Trane Clean Effects Air Purification System.
Air Conditioning Split Systems
While more common in other regions, the traditional Air Conditioning Split System is still found in many homes throughout Northern Virginia. These systems consist of an outdoor air conditioner and an indoor air handler. In our area, where winters can get chilly, many homeowners choose to upgrade these systems to heat pumps for year-round heating and cooling. Upgrading can also take advantage of energy rebates or incentives. Shown here is a Trane XR14 air conditioner paired with a Tem6 Variable Speed Air Handler.
Air Conditioning Split Systems With Gas Furnaces
Another widely used HVAC setup in Northern Virginia is the Air Conditioning Split System paired with a gas furnace. These Gas/AC split systems are common in Alexandria, Arlington, and other high-end Northern Virginia neighborhoods. They provide efficient and cost-effective heating during colder months. A typical system includes an outdoor air conditioner, a gas furnace, and an evaporator coil. Shown here is a Trane XV20 Variable Speed Air Conditioner paired with an 80% Variable Speed TUD Furnace.
Package Air Conditioning Systems
In Northern Virginia, including Alexandria and surrounding communities, many homes—especially modular and manufactured homes—use packaged HVAC systems. These are often Package Air Conditioners or Package Heat Pump Systems, and in some areas, Package Gas/AC systems are also common. Shown here is Trane’s XL15 2-Stage Package Heat Pump System.
Ductless Mini Split Systems
Ductless mini split air conditioning systems are a versatile solution for homes in Northern Virginia, including Alexandria and surrounding areas. While often used to cool additions or smaller spaces, these systems are also ideal for home offices, apartments above garages, and modular homes. Many ductless systems are available as multi-zone setups, allowing up to five individual indoor units—or a ducted air handler—to provide cooling throughout an entire home. Pictured here is a high-wall Mitsubishi/Trane ductless unit, commonly installed in bedrooms or small living spaces.
While mini splits are among the most popular systems we install, we also provide solutions for other HVAC types, including water-to-air heat pump systems and self-contained units.

What Makes Our AC Installations Better
No Shortcuts. No Piece-Rate Installs. Just Quality.
Some companies rush through two or more residential installs in a day—cutting corners to maximize profits. At Comfort-Tech, we assign only one installation per crew per day, and we take the time to do it right. Our techs are paid hourly (not per job), so there's no incentive to rush or skip steps.
We follow manufacturer specs, local codes, and our own high standards—every time. If ductwork needs to be updated or corrected, we bring in extra help or take the time needed to complete the job properly.
Your AC System Will Look as Good as It Performs
We know that even if you don’t understand every technical detail of your HVAC system, you’ll notice sloppy work. That’s why we pay close attention to both performance and appearance. A clean, professional installation shows pride in our work and gives you a system you’ll be proud to show off.

Air Conditioning Installation & Replacement FAQs
What is a SEER Rating on Air Conditioning Systems?
The SEER (Seasonal Energy Efficiency Ratio) rating measures an AC system’s cooling efficiency. A higher SEER rating means greater energy savings and lower utility bills. With rising electricity costs, it’s wise to invest in the highest SEER rating you can if you plan to stay in your home long term.
How much does a new air conditioner cost?
Costs vary by system type. Central split systems range from $6,000–$10,000. High-efficiency systems with variable speed compressors range from $10,000–$20,000. More important than cost is choosing a reputable contractor and reliable brand.
What size air conditioner do I need?
Sizing depends on your home’s square footage, insulation, windows, orientation, and more. The best way to determine the right size is with a professional HVAC load calculation.
How long do AC and heating systems last?
In Northern Virginia, most systems last 10–15 years. With excellent maintenance, some units last up to 20 years. Usage and environment play major roles in longevity.
When should I replace my AC or heating system?
Plan for replacement after 10 years, when the warranty expires, or if frequent repairs and rising utility bills become an issue. Don’t wait for a breakdown in the middle of a heatwave.
Why replace your old HVAC system?
- Energy Efficiency: New systems offer lower electric bills thanks to higher SEER and HSPF2 ratings.
- Better Performance: Enjoy quieter operation, better dehumidification, and improved comfort with modern variable speed and two-stage systems.
- Greater Reliability: Avoid inconvenient breakdowns. Replacing before failure ensures comfort and peace of mind.
- Rebates Available: Utility providers like Duke Energy, Teco Gas, and the cities of Northern Virginia and Leesburg offer rebates for system upgrades.
