A Pro Air 5HP 20-gallon compressor typically costs about $900-$2,400 new, with an estimated average near $1,550 for a standard shop-ready piston model. Final price depends on the pump type, voltage, included controls, shipping, and whether installation or air-line work is needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 5HP, 20-gallon compressor | $900 | $1,550 | $2,400 | Equipment only; pump and duty rating affect price |
| Freight or delivery | $50 | $125 | $300 | More for residential lift-gate delivery |
| Electrical connection | $150 | $400 | $900 | Existing circuit and distance matter |
| Installed project total | $1,100 | $2,075 | $3,600 | Includes typical delivery and basic hookup |
Typical price for a 5HP 20-gallon shop compressor
For a new Pro Air unit or a comparable 5HP, 20-gallon shop compressor, a practical equipment-only budget is $900-$2,400. A basic belt-driven single-stage model tends to fall near the low end; a two-stage pump, cast-iron construction, higher duty cycle, or longer warranty can push the price upward. The average estimate of $1,550 assumes standard commercial-grade equipment rather than a specialty industrial package.
At the tank size in the product description, the equivalent equipment price is roughly $45-$120 per gallon of tank capacity. That figure is only a comparison aid: compressor value also depends on delivered air volume, pressure, and ability to run continuously. Assumptions: new equipment, standard U.S. retail pricing, normal freight access, and no major electrical upgrades.
Budget about $1,500-$2,100 for a typical unit delivered and connected where a suitable circuit already exists.
How the pump, delivery, and hookup shape the quote
Compressor quotes can combine equipment, transport, electrical work, and accessories. Ask whether the listed price includes a motor starter, pressure switch, regulator, oil, and warranty, since packages differ. The table gives common planning ranges; dealer quotes may bundle several items.
| Quote item | Low | Average | High | Typical basis |
|---|---|---|---|---|
| Compressor and pump | $900 | $1,550 | $2,400 | 5HP, 20-gallon unit |
| Delivery | $50 | $125 | $300 | Local drop to lift-gate freight |
| Electrical labor | $150 | $400 | $900 | Existing circuit to new dedicated circuit |
| Air accessories | $40 | $150 | $350 | Hose, regulator, filter, or quick-connects |
| Removal or disposal | $0 | $75 | $200 | Old unit removal, if requested |
Electrical changes, rather than basic placement, are often the largest added installation expense. A licensed electrician may charge about $75-$150 per hour, with the final bill depending on the circuit, wiring distance, and local requirements.
Motor voltage and air output can change the price
Confirm the nameplate specifications before comparing a Pro Air listing with another 5HP compressor. A 230-volt, single-phase model may suit some small shops, while three-phase power can be required for other commercial equipment. A 5HP label alone does not establish air output; compare CFM at 90 PSI, pump speed, and duty cycle against the tools being used.
For occasional nailers or inflation, a lower-cost model may be adequate. Spray equipment, grinders, and multiple users can require greater sustained CFM, making a stronger pump or larger system a better match. A 20-gallon tank stores a limited air reserve, so it does not by itself guarantee that a high-demand tool can run continuously.
Check both voltage and CFM at 90 PSI; a mismatch can add hundreds of dollars in upgrades or lead to inadequate performance. An electrical run over roughly 50 feet, a panel without spare capacity, or a change from single-phase to three-phase service can materially increase the project quote.
Delivery and electrician time for a 20-gallon unit
A standard delivery may cost $50-$125 locally, while freight to a residence can reach $150-$300 when lift-gate service or appointment delivery is required. Confirm whether the carrier will place the compressor at the intended location; curbside delivery does not include moving it into a garage or shop.
Basic positioning and hookup can take about 1-2 hours if the floor is level and the correct receptacle or disconnect is already present. A new dedicated circuit may take 2-6 labor hours, excluding unusual panel work. Contractors commonly charge $75-$150 per hour, and minimum service charges of $100-$250 are possible.
Measure doorways and confirm power before scheduling freight or installation. A tight stair, long cable route, or inaccessible panel can require additional labor or equipment that is not included in the compressor’s advertised price.
Three realistic purchase and installation totals
A low-cost example is a $950 belt-driven unit, $75 local delivery, and $150 hookup using an existing suitable circuit, for a total of about $1,175. This assumes basic accessories are included and no removal is needed.
A typical shop example is a $1,550 two-stage model, $125 freight, $350 electrical connection, and $100 for a filter and hose. The estimated total is $2,125 before tax.
A higher-cost example is a $2,300 premium pump package, $275 lift-gate delivery, $800 for a new circuit, and $250 for removal and accessories. The total is about $3,625 before tax or any major panel upgrade.
These totals show why an equipment-only price can understate the amount due by several hundred dollars. State and local sales taxes vary, and some retailers calculate tax on delivery or accessories as well as the compressor.
Regional freight and electrical rates across the U.S.
Prices in large metro areas and high-cost coastal markets can run about 10%-25% above a Midwest baseline, especially for electrician time and delivery. Rural shoppers may see 5%-20% higher freight or service charges when dealers and contractors travel farther, even if the equipment price is similar.
Online pricing can look lower, but shipping a heavy compressor and arranging local warranty service can offset the difference. Compare the delivered price, return freight terms, and who handles warranty diagnosis before selecting a seller.
Compare installed quotes in the same ZIP code, not just advertised equipment prices. Regional percentages are planning estimates; dealer promotions, freight routes, and local labor availability can change actual quotes.
When a smaller compressor or repair costs less
If the tools require only intermittent air, a lower-horsepower compressor may cost less upfront and may work with existing electrical service. However, it should be sized to the tools’ CFM demand at operating pressure, not selected solely by tank volume. A 20-gallon tank does not compensate for an undersized pump during sustained use.
For an existing compressor, ask for a diagnosis before replacing the entire unit. Common repairs such as a pressure switch, belt, or check valve may cost roughly $100-$350 installed; motor or pump replacement can run $400-$1,000 or more. Compare the repair quote with the cost of a replacement that includes delivery and electrical work.
Repair makes the most sense when the tank is sound and the pump or controls are the isolated problem. A corroded tank, repeated overheating, or a repair approaching half the delivered replacement price can favor replacement instead.
Ways to lower the Pro Air compressor quote
Choose only the pressure and CFM the tools need, and avoid paying extra for a premium pump or control package that will not be used. Confirm whether the dealer includes a regulator, starter, and warranty rather than buying duplicate accessories. Request separate prices for the compressor, delivery, installation, and removal so each charge is easy to compare.
Preparing a level, accessible location and verifying electrical capacity before delivery can reduce return visits. If replacing an old unit, ask whether the seller offers a lower removal fee when disposal is arranged with delivery. Compare at least three written quotes with the same voltage, pump type, CFM rating, and delivery terms.
The most reliable savings come from matching the compressor to actual air demand and avoiding unneeded electrical or accessory upgrades. Do not reduce cost by skipping required grounding, overcurrent protection, or manufacturer-specified ventilation.
