Build Your Lennox Installation
Four quick questions about the job, and you’ll get three Lennox tiers laid out side by side, plus a checklist of what any quote should show you before you sign anything. No contact info needed to see the result.
Question 1 of 4
Here’s Where You Likely Land
A breakdown of Merit, Elite, and Signature Collection against what you told us.
Merit Series
Solid single- or dual-stage performance. Every Max HVAC Systems quote opens here.
Elite Series
Noticeably better performance without stretching into premium territory.
Signature Collection
Precise Comfort® variable-capacity tech, Lennox’s deepest warranty coverage.
These numbers reflect current Max HVAC Systems pricing for a common Northern Virginia system size. Home size, ductwork condition, and electrical work can shift the total, an in-home visit pins down the exact figure.
What a Lennox System Costs in Northern Virginia
For most Springfield homes, this lands as a four- to five-figure decision, and the spread inside that range is wide. A single-stage Merit changeout in a smaller townhome sits at one end. A zoned, variable-capacity Signature Collection system in a larger colonial sits well past it. Equipment is often the smaller half of that number, which is why two homes the same size can land thousands apart once ductwork, electrical, and comfort features enter the picture.
Northern Virginia pushes on that spread in its own way. A good share of Fairfax County’s housing stock is old enough that ductwork and panel capacity become part of the conversation, and split-level homes with original insulation often need more capacity than square footage alone suggests. Springfield’s humid summers also nudge people up a tier more than a dry climate would, since single-stage equipment can’t run long enough to properly wring moisture out of the air.
What Max HVAC Systems can say flatly: the in-home estimate is free on any new install, the full price goes in writing before equipment gets ordered, and it doesn’t move once you’ve signed. If the system turns out to be repairable instead of finished, the diagnostic runs a flat $90, and we’ll tell you straight which direction makes more sense.
What an Installed Price Includes
An HVAC installation price covers much more than the equipment itself. The final cost includes the system, preparation work, installation, testing, and everything required to get your new Lennox system running properly.
Lennox Equipment
The matched outdoor unit, indoor unit, coil, thermostat, and other required components selected for your home’s comfort needs.
Old System Removal
Removing the existing HVAC equipment, recovering refrigerant properly, and preparing the space for the new installation.
Installation & Startup Testing
Professional installation, system setup, performance checks, and startup testing to confirm the equipment is operating correctly.
Permits & Inspections
Required permits and inspections handled as part of the installation process where applicable.
System Connections
Refrigerant lines, condensate drainage, electrical connections, equipment pad, disconnects, and other components needed for proper operation.
Ductwork Adjustments
Sealing, modifying, or improving existing ductwork when needed to help the new system deliver better airflow and performance.
Warranty Registration
Submitting the applicable Lennox warranty registration after installation so your equipment coverage is properly documented.
What Every Quote Should Show You
Two quotes for the same Lennox tier can land thousands apart, and the gap almost always traces back to what one of them left out. Whoever you’re talking to, us included, here’s what to look for:
- A written load calculation
- never just a number carried over from the old unit
- Specific model numbers
- since “Lennox system” alone tells you nothing about what you’re actually buying
- Coil and line set confirmation
- the two components most commonly tacked on after the fact
- Clarity on permit responsibility and cost
- whether it’s separate or built in
- Installer-handled warranty registration
- since a system left unregistered can quietly lose coverage you were promised
- Documented startup numbers
- proof the refrigerant charge and airflow were actually checked
- Separated line items
- for ductwork and electrical, so equipment cost and home-related cost don’t get blurred together
- A straight answer on price changes
- after signing: ours doesn’t move; ask every company the same thing
Which Lennox System Are You Pricing?
Five categories of Lennox equipment cover most Northern Virginia homes, and the price on each moves for its own reasons. Here’s what each one runs on, and where to read further.
-
Lennox Air Conditioners
Cools the home while heating stays exactly as it is. The number moves with home size and tier, but the real swing factor is whether the indoor coil and line set get swapped alongside the outdoor unit; skip that on a full replacement, and efficiency suffers down the line.

-
Lennox Gas Furnaces
Built for homes already running on gas. Efficiency tier sets the baseline, but the flue and existing gas piping often decide the final number; older venting has a way of needing work once a technician actually looks closely.

-
Lennox Heat Pumps
One system doing double duty across both seasons, which makes it the natural pick for all-electric homes. Electrical panel capacity and how backup heat gets set up are what really drive the cost here, especially with how cold Northern Virginia winters can run.

-
Lennox Air Handlers
Pairs with a heat pump or all-electric setup to push conditioned air through the home. Cost tracks how closely the variable-speed capability needs to match the outdoor unit it’s paired with.

-
Lennox Ductless Mini-Splits
The fix for rooms ductwork never reached, or homes with no ductwork at all. Pricing runs per indoor unit instead of square footage, so the number of rooms needing coverage is really the whole conversation.

Paying for It Over Time
A system rarely fails in a convenient month.
Max HVAC Systems finances new installs through Service Finance, with several plan options built around different budgets, so the work can go in now while the cost spreads out.
Where We Provide Lennox Installation Estimates
Max HVAC Systems prices and installs across Springfield and the surrounding Northern Virginia region. Travel isn’t a line item on your quote, since most of this coverage area sits a short drive from the Springfield shop rather than a scheduled trip across the region. Maryland jobs sometimes carry a distance-based charge depending on how far out the call is.
Not sure we cover your street? One call settles it.
Cost Questions Northern Virginia Homeowners Ask
Ductwork, electrical, and access decide thousands of dollars of the job, and none of that is visible from a phone call.
Yes, on any new install. If the system might be repairable instead, that diagnostic runs a flat $90.
No. Oversized equipment cools in short bursts, leaves humidity behind, and wears out sooner. Size gets measured, not upgraded.
Most Northern Virginia homes fall between 2 and 4 tons. Try our Lennox size estimator for a bracket in about a minute.
