Frequently Asked Questions

How often should I schedule HVAC maintenance for my home?

We recommend scheduling HVAC maintenance twice a year—once in the spring for your cooling system and again in the fall for your heating system. This keeps your equipment running efficiently and helps catch potential issues early.

What are the signs that my HVAC system needs repair or replacement?

If you’re noticing inconsistent temperatures, rising energy bills, strange noises, or poor airflow, it may be time for a repair. Systems that are 10–15 years old or require frequent fixes might be better off replaced with a newer, more efficient unit.

How can I improve the energy efficiency of my heating and cooling system?

Simple steps like replacing air filters regularly, sealing ductwork, and scheduling routine tune-ups go a long way. We can also recommend high-efficiency system upgrades and smart thermostats to help reduce your energy use.

What types of HVAC systems do you install and service?

We install and service a wide range of systems, including central air conditioners, furnaces, heat pumps, mini-split systems, and packaged units. We’ll help you find the best fit for your home’s size and your family’s comfort needs.
