The main online retailers for heat pumps are Amazon, Home Depot, Lowe's, and manufacturer websites like Carrier and Lennox

Most people buying a heat pump online fall into two groups: those ordering a unit for professional installation, and those looking for a portable or window model to install themselves. The retailers differ by what they stock and what support they offer after purchase.

Amazon carries portable heat pumps and window units from brands like LG, Frigidaire, and Midea, with delivery to most addresses in two to three days. Home Depot and Lowe's stock both portable units and central systems, though central systems usually require you to contact a local installer through their site rather than ship the unit to your door. Manufacturer websites like Carrier.com and Lennox.com let you configure a system and find authorized dealers in your area, but they do not ship directly to consumers — they connect you with installers who handle the sale and setup.

Key Takeaways

  • Amazon and big-box retailers sell portable and window heat pumps that arrive ready to use, while central systems require professional installation through local dealers.
  • Home Depot and Lowe's offer price matching and return windows of 30 to 90 days, which matters if the unit does not perform as expected in your space.
  • Manufacturer websites do not sell directly but connect you with certified installers who handle the entire transaction and warranty.
  • Portable units cost $300 to $1,500 and work in single rooms; central systems cost $4,000 to $8,000 installed and heat or cool a whole house.

Portable and window heat pumps on Amazon

Amazon stocks portable and window-mounted heat pumps from LG, Frigidaire, Midea, and Haier. These units arrive fully assembled and ready to plug in, with no installation beyond running a hose to a window or vent. Prices range from $300 for a basic 5,000 BTU portable unit to $1,200 for a high-capacity model with smart controls.

The advantage is speed — most ship within two days to Prime members — and the return window is 30 days. The disadvantage is that Amazon's product pages often lack detailed specifications like noise level in decibels or exact cooling capacity for your room size. Read the customer reviews carefully; they usually mention whether the unit is loud or whether it actually cooled the space it was supposed to.

Check the warranty before you buy. Most portable units come with one year of coverage for parts and labor, but some brands like LG offer two years. The warranty is only as good as the brand's customer service, so look for reviews mentioning how straightforward it was to get a replacement or repair.

Central heat pumps through Home Depot and Lowe's

Home Depot and Lowe's both sell central heat pump systems online and offer installation services through local contractors. You can browse units by capacity (measured in tons, typically 2 to 5 for a house) and efficiency rating (SEER2 for cooling, HSPF2 for heating). Prices for the unit alone range from $2,000 to $5,000, but installation adds $2,000 to $3,000 more.

Both retailers offer price matching if you find the same model cheaper elsewhere, and both give you 30 to 90 days to return or exchange a unit if it does not work out. Home Depot's website lets you enter your zip code to see which models are in stock locally and available for same-day or next-day pickup, which matters if you need the unit quickly. Lowe's has a similar tool and also offers financing options through their credit card.

The catch is that you are buying the equipment only — installation is a separate contract with a local company. Home Depot and Lowe's will connect you with installers in your area, but you will need to get quotes and sign a separate agreement. Ask the installer about their warranty on labor; most offer one to two years, but some offer longer.

Buying directly from manufacturer websites

Carrier, Lennox, Trane, and Rheem all have websites where you can learn about their heat pump models and find authorized dealers near you. These sites do not sell the unit directly — instead, they let you enter your address and see which local installers are certified to sell and install that brand.

The advantage of going through a manufacturer's site is that you can compare their full lineup and read detailed specifications before you contact anyone. You can also see which models may have access to for federal tax credits (currently up to $2,000 for a heat pump installation, though this changes yearly). The disadvantage is that you have to contact multiple installers to get prices, and there is no centralized return policy — each installer sets their own terms.

Manufacturer websites often have a "find a dealer" tool that shows you the nearest certified installer and their contact information. Call or email at least two installers to compare pricing and warranty. Some installers offer extended warranties or service plans that others do not, so ask about that before you decide.

Comparing prices across retailers

A portable heat pump on Amazon might cost $600, while the same model on Walmart or Best Buy could be $650. The difference is usually small enough that shipping speed or return policy matters more than the price itself. If you need the unit in two days, Amazon wins. If you want to see it in person first, Best Buy has physical stores.

For central systems, prices vary much more because installation costs depend on your house layout, ductwork, and local labor rates. A unit that costs $3,000 in one city might cost $4,500 installed in another. Get quotes from at least two installers before you commit. Home Depot and Lowe's installers are usually competitive, but independent HVAC companies sometimes undercut them.

Do not choose based on price alone. A cheaper unit from an unknown brand might fail in five years, while a name brand with a good warranty lasts ten. Read reviews on the specific model you are considering, not just the brand. A Frigidaire portable unit with 4.5 stars and 200 reviews is more reliable than a generic brand with 20 reviews and no track record.

What to check before you order online

For portable and window units, measure your window or vent opening before you order. A unit that is too wide will not fit, and returns can take weeks. Check the noise level in decibels — anything above 50 dB will be noticeable in a bedroom. Read the cooling capacity in BTU and match it to your room size; a 5,000 BTU unit cools a small bedroom, while a 12,000 BTU unit handles a large living room.

For central systems, ask the installer whether the unit is compatible with your existing ductwork and thermostat. Some heat pumps work with old thermostats, others require a new smart thermostat that costs $200 to $400. If your house has no ducts, a ductless mini-split system is an option, but it costs more and requires professional installation.

Check the warranty details. Most units come with five to ten years of coverage on the compressor (the most expensive part) and one to two years on other parts. Some warranties are transferable if you sell the house; others are not. This matters if you plan to stay in the house for less than ten years.

Shipping, delivery, and installation timelines

Portable units from Amazon usually arrive within two to three days for Prime members. Big-box retailers like Home Depot and Lowe's offer same-day or next-day delivery for in-stock items in many areas, though delivery fees can be $50 to $150. Check the delivery fee before you add the item to your cart — it is sometimes hidden until checkout.

Central system installation takes longer. After you order, the installer will schedule a site visit (usually within a week), then order the equipment if it is not in stock (one to two weeks), then install it (one to three days). The whole process from order to running system is typically four to eight weeks. If you need heat or cooling before then, a portable unit can bridge the gap.

Ask the installer about their cancellation policy before you sign. Some will refund your deposit if you cancel before they order parts; others will not. If the installation date slips, ask whether they will provide a loaner unit or offer a discount on the final bill.

Frequently Asked Questions

Can I install a central heat pump myself if I buy it online?

No. Central heat pumps require a licensed HVAC technician to install, connect to refrigerant lines, and program the controls. Doing it yourself voids the warranty and is illegal in most states. Buy through a retailer or installer that includes installation in the price.

What is the difference between a portable heat pump and a window unit?

A portable unit sits on the floor and vents through a window or wall with a hose; you can move it between rooms. A window unit mounts in the window frame and stays there. Portable units are louder and less efficient, but they are easier to install and remove. Window units are quieter and more efficient but require a compatible window.

Do online retailers offer installation for portable heat pumps?

Amazon and Best Buy do not offer installation for portable units — they assume you will plug it in yourself. Home Depot and Lowe's sometimes offer installation for a fee, but it is usually cheaper to do it yourself since portable units need only a power outlet and a window vent.

Can I return a heat pump if it does not cool my room enough?

Yes, within the return window — usually 30 days for Amazon and 30 to 90 days for Home Depot and Lowe's. For central systems, the installer's return policy applies, not the retailer's. Ask the installer about their policy before you sign the contract.

Are there federal tax credits for buying a heat pump online?

Yes, but only for central systems installed in your primary home. The credit is up to $2,000 and applies to the equipment cost, not installation. You claim it on your tax return the year after installation. Portable units do not may have access to. Check the manufacturer's website or ask the installer whether the specific model you are buying qualifies.
