Inverness · 35242
HVAC done right along the 280 corridor.
HVAC repair Inverness is mostly multi-system work. Inverness, Greystone, and Highland Lakes are full of larger homes — 3,500 to 7,000 square feet — that were almost always built with multiple systems by the original builder. The most common HVAC service Inverness call we get from this part of 35242 is "the upstairs system never keeps up." The second most common is "the bonus room over the garage will not stay below 78°F in August."
It almost never is the equipment. It is the duct path through the kneewall. It is the missing return in the bonus room. It is a stuck blower wheel that has been clipped for years and nobody opened the panel to look. It is the original builder using a 4-ton condenser on a 2,800 sq ft second floor because that was the standard truck-stock unit. We open the panel. We measure. We document. Then we propose the smallest fix that actually solves the problem.
Most Inverness comfort complaints are duct problems, not equipment problems.HVAC 35242 · 280 corridor neighborhoods
Scope
HVAC services for Inverness homeowners.
- 01
HVAC repair, Inverness.
Diagnostics on dual- and triple-system homes in Greystone and Highland Lakes. We isolate which system is the real problem, in writing, before any part gets ordered. Capacitor, contactor, fan motor, refrigerant leak isolation, control board failures, ECM blower diagnosis — instrument-based.
- 02
HVAC installation, Inverness.
Whole-home installs along the 280 corridor — Manual J on each zone, Manual D on the duct, brazed under nitrogen, evacuated to 500 microns, charged by weight, commissioned with instruments. Written subcooling, superheat, static pressure, and temperature-split numbers handed to the homeowner.
- 03
HVAC services for larger homes.
Bonus rooms over garages, conditioned attic spaces, theater rooms, home gyms — all of these have predictable comfort issues we have solved repeatedly in 35242. Solutions usually cost less than homeowners expect because the fix is duct or return-air work, not a new condenser.
- 04
Multi-stage and zoning.
When a 5,500 sq ft home has one zone, we will not pretend that is fine. We design proper zoning with bypass-free dampers, real return paths in each zone, and controls that actually communicate (Carrier Infinity, Trane ComfortLink, or comparable two-way controls).
- 05
Coordinated dual- and triple-system service.
When a Greystone home runs three systems, we set them up to share thermostat staging logic where appropriate, balance refrigerant charges to matched superheat/subcool ranges, and document everything on one written commissioning sheet — not three uncoordinated truck calls.
280 corridor neighborhoods
Greystone, Highland Lakes, Eagle Point, Brook Highland.
Greystone
Larger lots, larger homes, almost always dual-system. Original builder equipment from the late 1990s and early 2000s is reaching natural replacement age now. The most common scope on a Greystone HVAC replacement is dual condensers and air handlers, with a careful evaluation of whether to keep the existing zoning or redesign it. Variable-speed inverter equipment (Carrier Infinity, Trane Variable Speed, Daikin Fit) tends to earn its keep on these homes.
Highland Lakes
Similar in scale to Greystone but with a higher percentage of homes built 2005-2015. Equipment is younger but starting to show the typical 12-15 year repair-cost climb. We do a lot of capacitor and condenser-fan-motor work in Highland Lakes, plus periodic preventive duct rework on the homes where the original builder skipped insulation on attic supply runs.
Eagle Point
Some of the largest stock on the 280 corridor — 4,500 sq ft and up. Triple-system installs are common. Coordinated commissioning matters most here because three systems running independently produce three different humidity readings in three rooms.
Brook Highland
Smaller average square footage than Greystone or Highland Lakes — typically 3,000-3,500 sq ft on tighter lots. Single-system or compact dual-system. The most common HVAC repair Brook Highland call is a mid-2000s air handler that has reached the end of its useful life, with the homeowner deciding whether to do a like-for-like replacement or upgrade to a variable-speed system.

FAQ
Inverness homeowner questions.
Do you do HVAC installation in Greystone and Highland Lakes?+
Yes. Both are core parts of our 35242 service area. Larger envelopes there demand careful Manual J load calcs zone-by-zone and proper Manual D duct design — exactly what we do. Most Greystone and Highland Lakes homes run dual or triple systems; we install and service them as one cohesive setup.
My Inverness upstairs system never keeps up — is that normal?+
Common, not normal. Almost always a duct or return-air issue, not the condenser. We will measure static pressure (target under 0.5" w.c.) before we suggest replacing equipment. Eight times out of ten on the 280 corridor, the upstairs comfort problem is a return-air path running through a kneewall that was never sized for current load.
Can you handle dual- and triple-system homes?+
Yes. Many of our 35242 clients in Greystone and Highland Lakes run two or three systems. We service them as one cohesive setup with coordinated thermostat staging, balanced refrigerant charge, and matched commissioning numbers — not three separate trucks running independently.
How much does HVAC installation cost on a 5,000 sq ft Inverness home?+
Range for a complete dual-system replacement on a 4,500-6,000 sq ft Inverness home is roughly $19,000 to $38,000 depending on tonnage, equipment tier (single-stage / two-stage / variable-speed), zoning controls, line-set length, and duct work scope. We quote in writing after one walk-through with a written Manual J for each zone.
Are you EPA 608 certified for HVAC service in Inverness?+
Yes. EPA Section 608 Universal Certified for refrigerant handling. Alabama HVAC license #[TBD-license]. Bonded and insured.
Why do larger homes on the 280 corridor need more careful HVAC sizing?+
Bonus rooms over garages, conditioned attic spaces, theater rooms, and home gyms each have their own thermal load that Manual J should account for separately. Treating a 5,500 sq ft Greystone home as one zone produces an oversized, short-cycling system. Treating it as three or four zones with proper duct design produces a quiet, balanced setup that lasts.
What HVAC brands do you install in Inverness?+
Carrier, Trane, Lennox, Daikin, Bryant, American Standard, and Mitsubishi (for ductless mini-split). We are brand-agnostic and specify per ACCA Manual S after the load calc, then verify the AHRI directory match for rated capacity before quoting.
