Straight answers on AC pricing
Know the work.
Plan for the cost.
A repair, a replacement system and a maintenance visit are different jobs. Start with the service you need, then see what the price covers and what can change your written estimate.

| Job and scope | Price / planning range |
|---|---|
| AC installation & replacement A complete central system is more than the outdoor unit. This planning range covers selected Farrell-supplied split and package replacements, with the installation work stated in each proposal. | $7,300–$13,500 Farrell-supplied central system projects |
| AC repair From a clogged condensate line or failed capacitor to a motor, valve or compressor repair. The problem and parts determine the price; a diagnostic-only visit is listed separately. | $300–$2,600 Selected repair visits and component work |
| AC maintenance plans Choose the annual plan that fits your system: $149 for one scheduled visit or $199 for two. A plan purchase and a repair during a maintenance visit are different charges. | $149–$199 Annual plan: one or two scheduled visits |
| AC tune-up A one-time tune-up checks operation and routine maintenance items. The current catalog starts at $129 for the stated visit; multiple systems and approved repairs add to the total. | $129–$155 Selected single-system routine visits |
| Ductless mini-split installation One room, multiple zones and several separate systems are different projects. We price the condenser, indoor heads, line sets, electrical work and installation scope together. | $4,500–$12,000 Farrell-supplied: one zone through two systems |
| Customer-supplied mini-split installation Installation only; you supply the equipment. Materials, existing connections and electrical scope vary. | $1,400–$3,500 Installation only; equipment purchase excluded |
| Commercial HVAC A diagnostic visit or small repair is different from a maintenance contract or a rooftop replacement. Start with the affected system and the work your business needs. | $185–$750 Selected diagnostic and small repair visits |
| Air purifiers & UV systems A replacement UV lamp, a new UV device and a whole-home purifier are different purchases. We check the existing system and explain the equipment and ongoing replacement needs. | $1,200–$1,800 Selected whole-home purifier installations |
| Whole-home dehumidifiers A whole-home dehumidifier needs the right capacity, controls, drainage and connection to your home. We assess the moisture problem before recommending equipment. | Written estimate Assessment and written installation estimate |
| Ventilation & airflow work An exhaust run, a duct repair and a whole-home ventilation system solve different problems. We identify the airflow path and quote the work your home actually needs. | Written estimate Price depends on the defined airflow work |
| AC filter replacement A standard filter swap, specialty media replacement and a multi-system maintenance visit are different jobs. We match the filter to the equipment and separate materials from the visit scope. | Written estimate Filter type, quantity and visit scope |
Some projects fall outside the shown bands. Subgroups have different sample sizes; read the guide before comparing prices. Customer-supplied equipment, optional upgrades, unusual access and multi-system projects need their own scope.
How we built these guides
Actual work. Clearly stated limits.
We checked completed job records and the charged line items, including quantities, discounts and related work. We separated equipment purchases from installation labor, routine visits from repair additions, and one-system jobs from larger projects.
The records were selected to compare scopes, not to calculate a statistical average. Older prices and discounts are identified as historical. Where a reliable comparison is missing, the guide explains what we need for a written estimate.
Bring these questions to your estimate.
- Who supplies the equipment, and which exact model is included?
- Does the total include the visit, permits and needed connections?
- Which electrical, duct, access or finish work is separate?
- What coverage applies, and what are the maintenance conditions?
- What is the complete written price before I approve the work?
A few answers before you call.
Are these Farrell Air Conditioning prices or national averages?
The repair and installation planning bands use selected completed Farrell Air Conditioning jobs, with current catalog prices shown separately for diagnostic visits, tune-ups and annual plans. Each guide explains its evidence and scope. These are not national averages, fixed quotes or a statistical average of every job.
Does every low price include the equipment?
No. The central-system headline covers Farrell-supplied equipment. Mini-split guides separate company-supplied equipment from customer-supplied installation. A replacement filter, UV lamp or maintenance visit is not the same purchase as a complete system.
What can change the written price?
Equipment, capacity, number of systems, access, electrical and duct requirements, permits and the actual fault can all change the work. The proposal should state equipment ownership, inclusions, separate work, fees and the total you approve.
Why do some services say written estimate?
A useful range needs comparable completed work with a clear scope. When our reviewed records mix different jobs or do not provide enough installation evidence, we explain what must be assessed instead of publishing an unsupported price.
Can I estimate a monthly payment?
Yes. Our financing page has a rough payment calculator for new-system planning. Enter your project amount and your own APR and repayment assumptions. It is not a credit offer or application; call our team to ask about Wisetack through Housecall Pro.
