Types of Heil Products

Heil is best known for its reliable and quiet air conditioners: its offerings range from 13 SEER rated models to industry-leading 19 SEER rated variable-speed units.

Air Conditioners

Choosing an air conditioner involves thinking about a lot of things, like building size, price range, quietness of the unit and energy efficiency.

AC units arerated in terms of SEER, or Seasonal Energy Efficiency Ratio, which measures the amount of cooling you get per unit of energy used up in the process. The SEER rating system tops out at 21 SEER, with a rating of 14.5 SEER or higher necessary to qualify for Energy Star rating.

Designed to fit in narrow lots, or to be stackable for multi-family housing, thePerformance 14 Compactcan operate quietly at as little as 66 decibels, as air flows through the pass-through design. It can reach 14 SEER efficiency with its single-stage compressor and fan motor.

At a rating of up to 17 SEER, thePerformance 16air conditioner is Energy Star qualified and can operate at as little as 70 decibels. A filter drier helps keep the unit running at peak efficiency and the tight wire grille panels protect the machinery while allowing for easy coil cleaning.

Meanwhile, top of the lineQuietComfort Deluxe 19features variable-speed operation and works with SmartSense technology to maintain the optimum comfort at maximum efficiency. This model also has high-tech communication capabilities for control and diagnostics, up to 19 SEER rating, and is eligible for a 10-year replacement warranty on the entire unit. This unit can operate at only 56 decibels.

Heil has furnaces in both oil and gas models, which are efficiency-rated by a percentage AFUE. AFUE stands forAnnual Fuel Utilization Efficiency, and calculates the amount of heat you’re getting for each unit of energy spent – the higher the rating, the more efficient the system.

Heil’s oil offerings reach AFUE ratings as high as 86.8%, as seen in theQuietComfort 87Low Boy oil furnace. This model boasts a lifetime warranty on its heat exchanger, and a 10-year unit replacement warranty. It operates at variable speeds to offer the most efficient heat as conditions require, and is capable of 77,000-154,000 BTU/h. Its compact design means it can be installed in low-clearance spaces.

Also an oil model, thePerformance 86furnace can reach up to 86.4% AFUE. It operates with a fixed blower motor and has a sturdy, insulated cabinet to keep operational noise to a minimum while it churns out 70,00-112,000 BTU/h. The Performance 86 is also eligible for a lifetime warranty on the heat exchanger and a 10-year warranty on parts.

Gas furnaces, meanwhile, are capable of reaching up to 98% AFUE. TheIon 98operates with a variable-speed blower motor and modulated gas performance that operates between 40 and 100 percent of its capacity for even temperature and efficiency at 60,000-120,000 BTU/h. As a high-end model, it’s also eligible for a 10-year unit replacement warranty and a lifetime heat exchanger warranty.

The lower-pricedPerformance 80gas furnace has a multi-stage blower and single-stage operation to keep your home cozy and on-budget. It reaches an 80% AFUE rating and comes with a 20-year limited warranty on the heat exchanger. It has a capacity of 5,000-110,000 BTU/h.

Heat Pumps

A range ofheat pumpsoffer temperature control in moderate climates, by taking heat out of the air outdoors and moving it in, or vice-versa. They’re often combined with furnaces in colder climates to increase heating power. Heil’s heat pump offerings begin at ae 19 SEER rating with theDeluxe 18heat pump. This unit comes with SmartSense technology and variable five-stage compressor operation for top efficiency.

ThePerformance 15heat pump still manages an Energy Star qualification, at a 15 SEER rating for electric heating and cooling, though it operates with a single-stage compressor at as low as 69 decibels.

Packaged systems

Packaged systems are a single unit that delivers heating, cooling, or both, with the entire unit outside the home. Heil’s packaged systems come in models that can reach up to 16 SEER.

TheQuietComfort Deluxe 16is a combined heater and air conditioner unit that delivers a 16 SEER rating and an 81% AFUE rating. It features a two-stage compressor and is capable of 40,000-130,000 BTU/h. It’s covered by a five-year replacement warranty on the unit, and a lifetime warranty on the heat exchanger.

ThePerformance 14is a packaged heat pump made for narrow lots and designed to sit on the ground. It’s got an extra-tough hail guard grill to keep the unit well-protected. Rated at up to 14.5 SEER and operating at as little as 73 decibels, this unit will keep the house comfortable and the neighbors happy at the same time. It’s also covered by a limited 10-year parts warranty.


As with most things, pricing of Heil’s products varies by how efficient, powerful, and effective a unit is. While all furnaces can heat and all air conditioners cool, how well they do the job is what affects the price. Knowing what a home needs is the first step to establishing a budget for a new home comfort system, and that is best done with the help of a qualified HVAC professional.

A packaged 6-ton gas heating/electric cooling combination could set you back around $5,100, for example, while air conditioner units are likely to set you back between $1,200 and $2,300 before installation.

ReviewsHeil is pretty well-known for being an economy brand, and they stand by that by making simple, durable and effective machines. They have some high-end numbers with perks and some budget-friendly picks to fall within the economy range. Negative reviews tend to focus on broken-down equipment which, while covered by warranty, causes some inconvenience. On the other hand, positive reviews talk about good performance and price. 

Heil offers a full line of furnaces, air conditioners, and heat pumps, and it can be tough to decide which one is right for you. Contact a certified HVAC pro to get specific pricing and guidance as to which system would work best for your home.
