Extreme Comfort Commercial Air

Preventative Maintenance Programs

Commercial heating and air conditioning systems are one of the biggest investments a company makes, so maintaining your building or office air conditioning and heating system on a regular basis is important.

Commercial air conditioning and heating manufactures require annual check-ups to keep your warranty valid.  At Extreme Comfort Air Conditioning and Heating, we provide annual system check-ups to maintain your manufacturer’s warranty.

These commercial air conditioning and heating system check-ups also enable us to identify minor problems (like small refrigerant leaks) before they lead to expensive repairs (like a $6,500 compressor replacement).

In addition, properly maintained commercial heating and air conditioning equipment runs more efficiently, which can save you money on your energy bills.

•Dirty air filters affect air quality and office productivity therefore we replace your office or building air filters 4 times a year.


•Our retail fee for a 18-point commercial air conditioning or heating check-up is $89.   These check-ups are included with our maintenance program.

•Scheduled by the tenant or property owner, semi-annual check-ups allow us to track the performance history of your air conditioning and heating system.  If a reading appears abnormal, we will have the ability to compare it to readings from prior visits.


•The best maintenance won’t prevent normal wear-and-tear so our Commercial Maintenance Program customers receive a 15% discount on all replacement parts.

•Our Extreme Comfort Air Conditioning and Heating service trucks are fully stocked with parts so we’re able to repair 99% of our calls on the first visit.

Annual Blower Belt Change

•Includes one FREE Blower Belt change per year.


•EPA (Environmental Protection Agency) tests have determined that as little as 1/10th of a centimeter of dirt or dust on an air conditioning unit coil can reduce efficiency by as much as 20%.  A 20% loss in efficiency means the average home owner may be wasting as much as $300 each year.

•Dirty coils are also the #1 cause of bacteria growth in duct work.  Poor indoor air quality has been directly linked to dirty coils and drains.  Dirty coils restrict air flow, expel odors, damage motors, decrease comfort, and lower a unit’s life expectancy

•Evaporator Coils not included.


•Guaranteed service within 24-hours of contact 365 days a year weather permitting.

•Your time is valuable so Commercial Maintenance Program customers receive a courtesy call 20-30 minutes prior to arrival.


•As an Extreme Comfort Commercial Maintenance Program contract owner, you receive our best discount of 15% off our hourly labor rates.


•New air conditioning and heating equipment can be a big investment.  Extreme Comfort Commercial Maintenance Program customers receive a minimum of a 10% discount off our already low, volume discount pricing.


•Refrigerant prices have risen due to mandates passed by the EPA.  Extreme Comfort Maintenance Program customers receive a 15% discount off R-22 or 410A systems.

•A leak check or leak repairs may be necessary before adding additional refrigerant.


•It is common for commercial business service companies to charge a fee for the time it takes to drive to your company (referred to as “Trip Charge” or “Travel Time”).  Depending on distance and demand, this fee can be as high as $100 or more. Our Maintenance Program customers never pay a Trip Charge.


•All replacement parts are warranted for a minimum of 1 year, regardless of manufacturer’s limited warranty.

•All of our labor is guaranteed for 60 days.  During this 60 day grace period following service, there is never a charge to re-diagnose your system.

Excellent service from Jonathan and Eric installing a new coil - friendly and very professional. Was very impressed that the phone was answered on the weekend and someone was out first thing next business day. It wasn't an emergency so waiting was fine but because someone answered, I knew we were taken care of. Was recommended by friends and I am very pleased.

I would sincerely like to thank Extreme Comfort Air for installing my new A/C unit yesterday. I recieved a call early morning from the crew letting me know their ETA. I was greeted by each crew member with a smile and a good morning to follow. Jonathan, Jose, and Victor were very pleasant and very considerate regarding noise level considering that I had just gotten off night shift. Jonathan, explained that the job would take approximately 6-8hrs. I appreciated being informed on the process. They cleaned up and provided me with a walk through. During the walk through we noticed one room wasn't getting any airflow. The crew came back in and reassessed the situation and discovered an air duct disconnected. They immediately fixed it. I'm so thankful for Home Depot utilizing professional and honest people. Extreme Comfort Air also set up my inspection with city and took care of all of my warranty stuff. I couldn't have found a better company to take care of my A/C needs.

What a great company! I live in another state and the job was handled remotely with precision. I had a complete system changed out by Jose and crew and the Install Manager Joey F stopped by and called me from the job and sent me photos of the installation. He made me feel good about my investment. I’m thankful my friend Ashley referred me to them. Thanks to Extreme Comfort AC and Team!!

Ron was efficient, patient, thorough, and left me feeling like it was the right choice to go with Extreme Comfort. He is a superb representative of your company. I decided to use Extreme Comfort because of your great customer service from the entire staff. I was well informed from start to finish. Keep up the good work and please tell Ron how good it was to have someone like him as the technician.

Thank you!

Earle came out today and spent about an hour thoroughly looking over my entire HVAC system. Instead of trying to sell me an expensive new system, he patiently showed me how to operate the dampers to control the airflow to trouble rooms upstairs. I've had three other contractors out and none addressed this simple solution. A couple the dampers were completely closed off and although I attempted to adjust them in the past they were stuck because of excess mastic. Long story short, he saved me a lot of money (at least temporarily), and it is that kind of honesty and knowledge that will be rewarded in the long run.
