Reviews by Central Air Conditioner Series


Central air conditioners do more than cool living spaces. They also enhance comfort by cleaning, circulating and dehumidifying the air. The main parts of a central air conditioner are the compressor, heat exchanger and cooling coil. 

Heil offers three series of central air conditioners: from most to least expensive, QuietComfort Deluxe, QuietComfort and Performance. 

Heil Air Conditioner Models

Seasonal Energy Efficiency Ratio (SEER) ratings determine the energy efficiency of these Heil AC units. The higher the rating, the more efficient the unit. The federal government requires a 13 SEER for units manufactured after 2005. To make it on the ENERGY STAR “Most Efficient” list, units must have a SEER of at least 18

QuietComfort Deluxe 19 HVA9

Heil’s flagship model is ENERGY STAR-rated with 19 SEER cooling. It’s available in two-ton to five-ton capacities. 

The five-stage variable-speed compressor and variable-speed fan optimize humidity and temperature control. SmartSense technology provides incremental adjustments to the compressor and fan. These adjustments keep indoor temperatures consistent. The QuietComfort Deluxe 19 is Heil’s quietest model at 56 decibels. Other features include a weather-resistant design and remote access with WiFi-enabled Ion System Control.

Heil Air Conditioner Installation Pricing

One source estimates installation costs for Heil air conditioners at $3,492 to $6,100. Variables impact total costs. For example, HVAC professionals charge different hourly labor rates. Sometimes, existing ductwork requires updating for maximum energy efficiency. When ductwork requires updating or expansion, the design work takes time. This Old House estimates an installation cost of $3,500 to $4,000 for a medium-sized home when ductwork is already in place. 

Contact a local independent HVAC professional for accurate pricing tailored to your home’s specific needs. Your contractor will calculate loads to determine your home’s air conditioning demands. The contractor will then recommend a unit with a cooling capacity that is sufficient but not excessive. 

Heil Air Conditioner Maintenance 

Heil recommends that owners clear away debris and vegetation from their units on a monthly basis. It is also important to arrange for an annual inspection by a qualified HVAC technician. This visit most often occurs in the spring before the arrival of the cooling season. The technician will perform the following tasks: 

  • Inspect the cabinet, replacing anything that’s damaged or severely rusted
  • Clear any dirt, dust or debris found inside the unit
  • Inspect and clean the condenser coil, rinsing with fresh water
  • Inspect the fan and motor
  • Repair/replace overheated or otherwise damaged wiring/components
  • Tighten loose connections 
  • Inspect electrical disconnections, repairing or replacing if needed
  • Check the refrigerant system 

This annual visit also keeps your warranty in effect.

Heil Air Conditioner Warranties

Heil’s No Hassle Replacement Limited Warranty provides a one-time replacement of a compressor, coil or heat exchanger failing due to defect. No Hassle Limited Warranty periods are one, three, five or 10 years depending on the model. With top-of-the-line units, you must

Very Unsatisfied

We have had this unit in our home for 3 years and have gone through 2 compressors. It cools and heats wonderfully until the compressor goes out, no warning, just poof there it goes. Presently we are running 2 window units and 4 ceiling fans to assist this unit in keeping our home cool. And no, we do not frost the windows with extreme temperatures. Unit is set at 74 degrees. We were told that if the unit goes out again it would be best to replace it altogether. Most assuredly it will not be a Heil going back into our house. Carrier, here we come. It may cost more but we had one in our previous residence and, other than the installation, it cost us nothing and my utility bill was much cheaper.

"They don't last!"

1.0 rating
Very Unsatisfied

Purchased new 2012 and have had to have it charged every year except the year it was installed so it lasted a year. Apparently, the leak wasn't bad enough to be able to check for leaks but just bad enough to make it not work. Each year more needs to be added so the leak is getting worse and now the coil needs to be replaced. Worked for 1 year and then nothing but problems since. I will never buy anything Heil again!

"Crappy evaporator coil"

1.0 rating
Very Unsatisfied

After we had this system installed, we noticed the air was warmer and clammier than the prior unit at the same t-stat setting. We had to lower the t-stat down a couple of degrees to get the same comfort. Which meant the unit ran practically all the time! I installed a whole house dehumidifier and that did the trick, and we were able to then raise the t-stat temperature back to the pre-Heil setting, but I shouldn't have had to do that. In the year of running the unit without the dehumidifier, a couple of the vents dripped water occasionally and mold/mildew formed on our cathedral ceiling in the living room, which I blame on the poor humidity climate control. Not cool, Heil. Never Heil again.

"Broke down twice in 18 months"

1.0 rating
Very Unsatisfied

We brought a 14 SEER unit in September of 2016. Going into our first year of having the unit the coil got a leak in it. We got that fixed under warranty. Then in May of 2018, the compressor went out. This Heil unit has broken down twice in 18 months. We called to get the unit fixed, they will replace the compressor but we have to pay 600 dollars to fill it back up. To buy a unit costing thousands of dollars and their part broke down. The company should be looking into the issue but International Comfort Products doesn't care about their products or the people who buy their units. I know companies are out to make money but they should take care of this issue. 18 months, two major issues. When you call the company, they say, "I'm sorry and understand your frustration but we can't help you." Thanks a lot for nothing.

Reading the negative reviews of Heil HVAC equipment one thing is clear. The install is most likely the issue on the majority of the issues. I have installed many a/c units over my time in the industry and have had to go back on install other so called contractors have done and had to inform the homeowner that they have a bad install. Homeowners need to thoroughly research the contractors before deciding on the one to do the install for them. I installed an ICP product on my sisters house in 2005 and have not had to do anything to it other then clean the condenser coil and keep the drain line clear on the ahu. For those who read this need to know this Carrier owns ICP and a Heil unit is essentially the same thing as a Carrier. The product is solid and experiences no more issues than all the other brands. The warranty is 10 years just like other brands plus the Mainline Heil carry a 5 year no Hassle warranty, if you choose to go with an ICP product make sure you have it installed by an ICP Product dealer (contractor). They know the systems better than those that are not ICP dealers and also know the warranty issues (not made up issues like "this brand typically has blower motor problems" which I read in a review) This goes for Carrier, Trane, Lennox etc. Use the Dealers for those brands to do the install. You go with cheap contractor you get a cheap install and that is not the equipment's fault. One last thing in one of the review the individual said and I quote "Thank god I purchased the extended warranty" The Heil equipment comes with a 5 year parts out of the box and when registered within 90 days of install it get another 5 years for total of 10 years ( like most brands) so if he paid for an additional 5 years he got ripped off. Do your homework before you decide.
