Service Agreements

Heating and cooling systems often fail when you need them most—on the coldest winter day or during a scorching summer heat wave. Our service agreements help protect your investment by keeping your system running efficiently and reducing the risk of unexpected breakdowns. With regular check-ups, we can catch minor issues before they turn into costly repairs, extend the life of your system, and help you save on energy bills.



As a program member, you receive two performance tune-ups per year, 24-hour priority service, and discounts on parts, labor, and new unit installations. Additional benefits include energy-saving coil cleaning and a 30-day labor warranty on all services. Our agreements are designed to fit your needs, with multi-year options and tailored recommendations, giving you peace of mind that your home will stay comfortable year-round.

Your Investment In Our Service Agreement Includes:


Two Performance Tune-Ups Per Year – Having your system checked regularly enables us to keep your unit running as efficiently as possible, which saves you money on your utility bill month after month. These regular check-ups also enables us to catch problems such as loose or burnt wires, before they lead to a larger problem such as motor failure.

24 Hour Priority Service, 365 Days/YR – When you have an emergency, you can rest assured CSI Mechanical LLC…WILL BE THERE! Our commitment to program customers means we will have a technician to your door within 24 hours of calling our office.


20% Off Replacement Parts – Example of savings: if the cost of a blower motor replacement was $400, you would save $80 on the repair.


20% Off Repair Labor – Our discounted rates save you money with every service call. Our repair trucks are fully stocked so we are able to repair 99% of calls on the first visit.


Energy Saving Coil Cleaning – Dirty coils reduce efficiency and cause your unit to work harder and shorten the life expectancy of your unit. Your unit will cost you more month after month on your utility bill if the coils are not kept clean. Test performed by the EPA explain that as little as 1/10th of a centimeter of dirt or dust on a coil could reduce efficiency by 21%. Since the average homeowner’s heating and cooling bill is $1,500 per year, a 21% loss in efficiency means you could be wasting up to $315 each year.


10% Off New Unit Purchases – If or when it’s time for a new energy-efficient unit, you receive 10% off the complete installation. The average unit today is over $5000 installed. The savings typically pays for the initial cost of the service agreement.


Labor Warranty – All of our labor services are warranted for 30 days. If you have a problem within 30 days of service, there will be no charge to come back out and diagnose the problem. We stand behind our work.
