Why a Mini-Split Beats Extending Your Central System
If you converted a bedroom, garage, or detached studio into a home office, your central HVAC was sized for the original house. Adding load on the existing system makes the rest of the house uncomfortable and your office never quite right. A dedicated mini-split solves both problems:
- Independent thermostat — set your office to 70°F without freezing your spouse.
- Quiet enough for Zoom — 19 dB is below a whisper.
- Inverter efficiency — runs all day on the equivalent of a single light bulb.
- No duct work — installs in a day.
Sizing for a Dallas Home Office
- 120-200 sq ft (bedroom conversion): 9,000 BTU
- 200-350 sq ft (bonus room or large bedroom): 12,000 BTU
- 350-500 sq ft (converted garage, single bay): 18,000 BTU
- 500-700 sq ft (detached studio or two-bay garage): 24,000 BTU
Dallas heat and west-facing windows push sizing up. We do a Manual J load calc on every estimate.
Sound — The Zoom Call Test
The wall cassette runs 19-22 dB on its lowest fan setting. For reference: a whisper is 30 dB. You will not hear it on a call.
The outdoor condenser runs 45-52 dB — about as loud as a refrigerator. Keep it 6+ feet from any window where you take calls.
Installed Cost for a Dallas Home Office
- 9k-12k BTU single-zone (Gree): $4,800 - $6,400
- 9k-12k BTU single-zone (Mitsubishi): $7,200 - $9,500
- 18k BTU single-zone (garage conversion): $6,800 - $9,800
A bedroom-conversion office in most Dallas homes is $5,200 installed, Gree, in about 6 hours.
Tax Write-Off
If you use the office exclusively for business, the install cost may qualify for Section 179 deduction as a partial business expense. Talk to your CPA — we provide an itemized invoice.
