Extreme Comfort Commercial AC Service

Preventative Maintenance Programs

Commercial heating and air conditioning systems are one of the biggest investments a company makes, so Commercial AC Service and Maintenance for your 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 ac service 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 commercial ac 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 for all commercial ac service repairs.


•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.

We have used Extreme Comfort for years. They are just the best. Joey comes out twice a year and makes sure everything is working correctly. We had our attic insulation changed 2 years ago and it was very tricky to get the vents and dampers in the attic to work as needed. Joey went the extra mile, always. I recommend this company without any reservations whatsoever. They are terrific.

Extreme Comfort Air Conidtioning and Heating was excellent. Last year I replaced a part on my air conditioner and it lasted me through the summer. This year the same unit gave out and I needed to replace with a new one. Because I live in a condominium, the a/c unit needed specific measurements. Extreme Comfort walked me through the whole process and I was really impressed by their professionalism and patience.
Great communication on status of arrival time. They provided excellent customer care during the whole installation process. I highly recommend Extreme Comfort!

I chose Extreme Comfort to install a 3 ton 16 SEER system. This included the exterior compressor, interior furnace and interior coil. We received two bids. Earle was patient, reasonable and knowledgeable during the quote process and listened to my thoughts and concerns. He did not attempt to oversell me or speed through the process. I felt like I received a reasonable price. On the day of service Tony, Vicente and Noel showed up and got straight to work. They left my home in the same condition they found it and walked me through some of the components of the interior unit, furnace and exterior unit. I will use them to service the unit in the fall and will hope the new system provides great cooling and heat for the next 10-15 years.

These guys are fantastic, the owners are fantastic! I initially received three quotes. Mistakenly I subsequently went with the lowest bid. (Beware fast talking shady individuals who need money to start!-never give them money up front!) HUGE mistake. Extreme saved the day, installed my new air unit, my only regret is not giving my business to Extreme from the start! I could have afforded a new heater as well had I not given my money away to someone so short of integrity. Extreme's technicians were professional, courteous and hard working.
