HEIL Air Conditioners Review

HEIL has been manufacturing quality products for over 100 years. The company tests every unit it produces with quality, energy efficiency, and reliability as its goal. If you’re looking for a new air conditioning unit, its models are worth considering.

Energy efficiency is a must unless you want to pay high utility bills. HEIL units have good SEER ratings, with most units above the national minimum of 13. A SEER rating measures a unit’s efficiency at removing heat from a space. Six of its 13 models are also ENERGY STAR certified.

Automatic heating and cooling sensors can help with efficiency. HEIL’s top model includes SmartSense technology and energy-smart Ion System Control with Wi-Fi capability, which senses conditions and adapts output. The Ion System Control with Wi-Fi capability lets you control your unit remotely.

Three of its other models contain the Observer communicating system, including the Observer communicating wall control with Wi-Fi capability. It performs a similar function to improve your energy savings and enhance comfort. Pricing for units varies depending on the unit’s energy-efficiency, noise level, and the size of the area you want to be cooled.

Some of the most energy-efficient air conditioning units on the market
Sells one of the quietest A/C units in the industry
Some models have extra durability features
Not all models are ENERGY STAR rated
Some models’ SEER ratings fall below the minimum requirements in some states

HEIL builds its units to last. Two models have durability features, including protective corner posts and a tight wire grille to withstand bad weather and debris. The company believes in its models and offers no-hassle limited replacement warranties. If you’ve had issues with A/C units dying after a few years, this will be reassuring.

One major drawback to the brand is that not all of its units meet Energy Star standards and some models are below SEER requirements, so make sure you know the product’s capabilities before purchasing.

HEIL Overview

Energy efficiency – SEER rating

HEIL’s models range in energy efficiency from the national minimum SEER rating of 13 up to 19 in its most expensive model.

A SEER rating measures an air conditioner’s energy efficiency. Higher numbers indicate a more efficient unit. It’s calculated by dividing the total heat (measured in BTUs) a unit removes from a house during the typical air conditioning season by the total electricity used during that same period. The more efficient a unit is at cooling your home, the lower your utility bill.

When selecting the best HEIL model for your needs, you’ll have to strike a balance between cost and efficiency. The cost of more efficient models is at least a thousand dollars higher than its less-efficient options, but you could recoup that cost in energy savings.

Warranty options

HEIL offers four different warranty periods on its air conditioning units.. Models come with no hassle replacement limited warranties for periods of one, three, five, or 10-years. The ten-year warranty applies to its top-of-the-line products, the five-year warranty to the mid-tier units, and the one or three-year warranties to standard-level products.

The warranty only covers the compressor, coil, or heat exchanger in your unit. If any of them fail during the warranty period, HEIL will provide a one-time replacement in the form of a comparable unit. While you don’t have to do anything to receive the main warranty, you do have to register your product online to receive their 10-year parts limited warranty.

Purchasing an air conditioning unit is a big investment. Its warranty protects you from a breakdown in the heat of summer, which could be dangerous for both the elderly and infants, not to mention the unexpected replacement cost. HEIL’s warranties are adequate but not great, and some competitors do offer more protection.

Installation and maintenance

Most air conditioning manufacturers don’t sell directly to consumers, and HEIL is no exception. The company distributes its products through a network of independent heating and cooling companies and aren’t sold at national retailers such as Lowe’s or Home Depot. When you visit the webpage for one of its units, you’ll see local dealers listed to the left.

HEIL provides owner’s manuals on its website, in which it advises homeowners on routine maintenance. The company instructs homeowners to clean filters often to keep them from getting clogged and check your condensate drain occasionally to make sure it’s not blocked. If you live in a coastal area, every three months you’ll need to wash all exposed surfaces and the outdoor coil to keep the weather from corroding the unit.

Staying on top of these simple maintenance tasks will help keep your unit operating efficiently.

Sound rating

Typically, an air conditioning unit sits outside your home, likely close to the exterior wall or windows. When it’s in operation, you could hear the noise of the motor and fan in your home, which is why a unit’s sound rating matters.

HEIL provides minimum decibel ratings for its air conditioning models and actual sound levels could rise much higher. Minimums range from 56 to 76 decibels (dB). The range of 50 to 60 decibels is similar to conversational speech. At higher levels, between 80 to 90, it’s comparable to a lawnmower.

Obviously, given these differences, you’ll want to carefully consider where your air conditioning unit will be placed outside and how much sound will travel through walls into your house.

HEIL vs. Goodman Air Conditioners

Goodman, formerly an American company, was acquired by Japanese company Daikin in 2012 but still manufactures its products in Texas. It sells a limited number of air conditioning models, which have less efficiency and are louder than most of HEIL’s units.

Only two of its five models have received an ENERGY STAR rating, further limiting your options if efficiency is a priority in your search. Not one of its units has a sound rating as low as HEIL’s quieter units, and none dip below the level of a shower or conversational speech.

Goodman’s limited compressor warranty has a lifetime guarantee, unlike HEIL’s time-limited warranties. Its warranty on parts covers you for ten years, as does its replacement limited warranty. Overall, it has more basic offerings than HEIL but with a better warranty overall.

HEIL vs. Rheem Air Conditioners

One of the largest manufacturers of heating and cooling products in North America, Rheem has established a reputation for innovation and reliability throughout its 100-year history. It sells seven air conditioning models, all of which come with a 10-year limited lifetime warranty.

While Rheem’s SEER ratings are comparable to HEIL’s, only five of its models are ENERGY STAR certified. Only two have EcoNet technology, which monitors and provides air and water control to maintain comfort and efficiency. More expensive models also have PlusOne Triple Service Access, which is a larger corner service access that enables faster and easier repairs.

Installation costs vary by model and location, but across the board, it’s cheaper to have a Rheem unit installed than a HEIL unit. This is particularly true for their high-end line, and if you’re buying at the top of the range Rheem could be the cheaper option.
