Preventative Maintenance/Maintenance Agreements:

Preventative maintenance is designed to help extend the life of your unit, prevent any major problems from happening and to keep your system running efficiently. We recommend twice a year checkups to properly maintain your system.
Maintenance Agreements are available. Here are the benefits of signing a Maintenance Agreement:
  • Worry Free Scheduling – Our office will handle contacting you to set up your maintenance appointments. There is no need for you to worry about remembering to schedule your appointments – we do that for you!
  • Lower Energy Costs – Preventative Maintenance can help to extend the equipment life and improve efficiency of the unit and help to lower future repair bills.

  • Receive a $20 Gift Card when you purchase a maintenance agreement. Just our way of saying thanks.
Computerized heat load calculations:

These are designed to properly calculate the size of the cooling & heating system for your home. If a system is too small for your home, the unit will not be able to keep your home cooling properly. If a system is too large for your home, high humidity problems can occur, opening the door for harmful substances, such as bacteria and mold.

Indoor Air Quality:

Many kinds of bacteria and viruses can pass through the air inside our homes. They can thrive on the inside of our AC & Heating systems. With the aid of a whole house air filtration system or an ultraviolet light system it can filter out the pollutants in the air and help you and your family breathe easier.

Commercial Installation & Service:

Brendan’s A/C & Heating can help install or repair systems for Commercial Applications. We work with Contractors and Business Owners to get the most efficient systems possible and keep the business flowing as normal without major interruptions.

Air Balancing:

Certified by the National Balancing Institute for Residential & Light Commercial Air-Balancing. We can Air-balance your Commercial or Residential Systems. We provide reports to homeowner & business owners or engineers to show that the system is performing within the range of specifications.
