It seems like heating systems become more efficient every year. This is partially due to changes in regulations and continuous improvements in the industry. With the new changes come more efficient units and lower energy bills.

Important!

If your system is more than 15 years old and no longer properly heats or cools your home,
it may be time to consider an HVAC replacement.

Our Process

The team at Allegiance Heating & Cooling will come to your home, examine your existing system and give you an honest evaluation of whether to fix it or forget it. If you do decide to replace your air conditioner, heat pump, mini-split or other home comfort system, reach out to our team first. With decades of experience and intimate knowledge of many makes and models, we’ll help you find the most budget friendly resolution for your heating and cooling needs.

Choosing a Thermostat

It’s important to choose an experienced HVAC contractor so that you get the right BTU and SEER ratings and choose a thermometer that’s compatible with your existing equipment. Should you choose a programmable thermostat, we can install it and show you how to operate it. As well as backing up our work with a satisfaction guarantee, we offer flexible financing options including many ways to pay.

Expert Heating and Cooling Maintenance

You wouldn’t keep driving your car year after year without proper maintenance. Similarly, your HVAC system needs regular tune-ups to keep in shape. Ask about our monthly maintenance plans that include cleaning the equipment, lubricating moving parts and making sure that your machine is operating and it’s best.
