What a Full HVAC Installation Covers

We handle every part of the job, from load calculation to final test run.

All services
equipment selection and honest recommendations work, professional service in Leesburg, VA

Load Calculation and System Sizing

We don't guess. Before recommending equipment, we calculate your home's heating and cooling load based on square footage, insulation, window placement, and ceiling height. An oversized system short-cycles and drives up your energy bill. An undersized one runs constantly and still can't keep up on a 95-degree August afternoon.

Equipment Selection and Honest Recommendations

We carry high-efficiency systems from factory-certified product lines and explain the real tradeoffs between tiers. If a mid-efficiency unit is the right call for your budget and home, we'll say so. We're not going to push the most expensive equipment on the shelf when it doesn't fit the situation.

AC Installation and Replacement

Whether you're replacing a 20-year-old unit or installing a new AC system in a home that didn't have central air, we handle the full scope: refrigerant lines, electrical connections, condensate drain, and outdoor pad or wall mount. Every system gets pressure-tested before we leave.

Heat Pump Installation

Heat Pump Installation

Heat pumps are increasingly popular in Northern Virginia's climate because they handle both heating and cooling efficiently through most of the shoulder season. We assess your home's insulation and electrical capacity before recommending one, and we're honest when a gas furnace backup makes more sense for your situation.

Furnace and Heating System Installation

Furnace and Heating System Installation

New furnace installs require proper venting, gas line sizing, and flue configuration, details that affect both efficiency and safety. Our licensed HVAC professionals handle code-compliant installation and test combustion and airflow before the job is complete. If you need a standalone heating system or a dual-fuel setup, we'll spec it correctly.

Ductwork Assessment and Repairs

A new system can't perform in leaky or undersized ducts. Before installation, we inspect the existing duct layout and identify restrictions, disconnections, or sections that won't support the new equipment. If the ductwork needs work, we tell you upfront. Not after the install when you're already wondering why rooms aren't heating evenly.

How It Works

Our HVAC Installation Process

  1. Site Assessment and Recommendation

    A certified technician visits your home, measures the space, inspects existing ductwork and electrical capacity, and reviews your current system. You get a clear recommendation with honest options, not a sales pitch for the highest-margin unit.

  2. Installation Day

    Our crew protects your floors and work areas, removes the old equipment, and installs the new system to manufacturer specifications. Factory certification means we follow the exact procedures required to keep your equipment warranty intact.

  3. Test, Balance, and Walkthrough

    We pressure-test refrigerant lines, verify airflow at every register, confirm thermostat communication, and run a full heating and cooling cycle before we pack up. Then we walk you through how to use the system and what to watch for.

Repair vs. Replace

When Replacement Makes More Sense Than Repair

This is one of the most common questions we get, and honestly, there's no universal answer. A system older than 15 years that's needing its second or third significant repair is almost always better replaced than fixed. You're spending money to extend the life of equipment that's already operating at reduced efficiency. On the other hand, a 7-year-old system with a failed capacitor or a refrigerant leak is a repair, not a replacement. We won't push you toward a new system when a repair is the right call. If you're unsure, our HVAC maintenance inspection includes an honest assessment of remaining useful life. We'd rather give you a clear answer now than sell you a system you didn't need.

Heat Pump vs. Traditional Heating for Leesburg Homes

Northern Virginia's climate sits in a useful middle zone for heat pump performance.

When a Heat Pump Wins

Leesburg's winters are cold but not relentlessly so. Modern cold-climate heat pumps maintain efficiency down to around 5 to 10 degrees, which covers most of what a typical Loudoun County winter throws at you. If your home is well-insulated and you're primarily looking to reduce energy costs, a heat pump is worth serious consideration.

When a Gas Furnace Still Makes Sense

Older Leesburg homes with existing gas infrastructure and ductwork sized for high-volume airflow often heat more reliably with a high-efficiency gas furnace. The upfront install cost can be lower, and the system performs predictably regardless of outdoor temperature. A ductless mini-split is also worth exploring for additions or rooms with no existing duct runs.

Dual-Fuel Systems

A dual-fuel setup pairs a heat pump with a gas furnace backup. The heat pump handles most of the heating season efficiently, and the furnace kicks in only when temperatures drop below the heat pump's efficient operating range. It's a strong option for homes that want the efficiency gains without giving up reliable cold-weather performance.

What Loudoun County Homeowners Say

“⭐⭐⭐⭐⭐ Excellent Service – Highly Recommend Brick Street Plumbing Water Heaters I recently had my entire HVAC system replaced after my old unit had been in my home for over 20 years. I requested an estimate through Home Depot, and they referred me to Brick Street Plumbing. Water Heaters, From beginning to end, my experience was excellent! Brian came to my home, carefully explained the different options available, and walked me through the entire installation process. He was very professional, knowledgeable, patient, and always available to answer my questions. Communication with Brian was outstanding throughout the entire project. One of the best parts of the installation was that they were able to relocate my water heater into an unused space in my basement. This made the entire HVAC area much more spacious, organized, and accessible. I am extremely happy with how everything turned out! I also want to recognize Austin, Gmo, and Dani for their excellent work. They were professional, hardworking, respectful of my home, and paid great attention to detail. The entire team did an amazing job! Replacing an HVAC system is a major investment, but Brick Street made the entire experience smooth and stress-free.

HVAC Installation Questions

What's the difference between HVAC installation and HVAC replacement?
Installation typically refers to putting in a system where none existed before, or doing a complete system overhaul that may include new ductwork, electrical upgrades, and line sets. Replacement is swapping out the equipment on an existing system that already has compatible infrastructure. The process is similar, but replacement is usually faster and less invasive. Either way, a load calculation should happen first.
How do I know if I actually need a new HVAC unit or just a repair?
Age and repair history are the two biggest factors. A system under 10 years old with a single component failure is almost always worth repairing. Once a system crosses 15 years and you're on your second or third repair, the math usually favors replacement. Declining efficiency is another signal: if your energy bills have climbed steadily without a change in usage, the system is likely working harder than it should. Our AC repair team can assess that honestly.
How long does an HVAC installation typically take?
A standard split-system replacement on a home with existing ductwork generally runs one full day. More complex jobs, dual-fuel systems, homes with significant ductwork modifications, or multi-zone setups, can run into a second day. We give you a realistic timeline before the install date so you're not left guessing. We won't tell you a job will take four hours when it's an eight-hour job.
What does factory certification mean for HVAC installation quality?
Factory-certified technicians are trained and tested by the equipment manufacturer on installation procedures specific to that product line. It matters for two reasons: first, the install is done to the exact spec the manufacturer designed, which affects efficiency and lifespan. Second, most manufacturer warranties require factory-certified installation to remain valid. A non-certified install that voids your equipment warranty is a problem that shows up two years later, not on install day.
Do older Leesburg homes need ductwork modifications when installing a new HVAC system?
Sometimes, yes. Homes built in the 1970s and 1980s often have ductwork sized for older, lower-efficiency systems that moved air differently. A modern high-SEER system paired with undersized ducts will underperform and wear out faster. We inspect the existing duct layout before recommending equipment, and if modifications are needed, we tell you upfront with a clear explanation of why. If your home has no duct runs at all, a ductless mini-split is worth exploring.
What's involved in properly sizing an HVAC system for a Loudoun County home?
Proper sizing starts with a Manual J load calculation, which accounts for your home's square footage, ceiling height, insulation levels, window area and orientation, and local climate data. Loudoun County's summers push into the mid-to-upper 90s with significant humidity, and winters dip into the teens during cold snaps. Both extremes have to factor into sizing. A system that's even 20% oversized will short-cycle, leaving your home humid and your energy bill high. Getting this right at install is far cheaper than correcting it later.
