Frequently Asked Questions
Have questions about HVAC replacement, preventative maintenance, or smart thermostat upgrades? Here are answers to common questions local homeowners ask before booking. If you need immediate service or have a custom inquiry, reach out today we’re always happy to help.
How often should I have my heating and cooling system serviced?
We recommend professional HVAC maintenance twice a year—once in the spring for your air conditioning and once in the fall for your furnace or heat pump—to ensure peak performance and prevent sudden breakdowns.
How long does a full HVAC system installation take?
Most standard residential HVAC replacements are completed in just 1 day (about 6 to 8 hours). Complex custom ductwork modifications or conversions may take 2 days.
What is included in a preventative maintenance tune-up?
Our comprehensive tune-ups include inspecting electrical connections, cleaning coils and blower components, testing refrigerant levels, checking thermostat calibration, clearing condensate drains, and ensuring overall safe operation.
Why is my AC or furnace making strange noises?
Unusual noises like squealing, banging, or rattling often indicate loose belts, failing motor bearings, or loose mechanical components. If you hear persistent noises, turn off your unit and schedule a diagnostic check to prevent further damage.
Can a smart thermostat really help lower my energy bills?
Yes! Smart thermostats optimize your heating and cooling schedules based on your routine, allow remote mobile adjustments, and track energy usage, typically saving homeowners 10% to 15% on annual utility costs.
How do I know if it’s better to repair or replace my HVAC unit?
As a general rule, if your system is over 10 to 12 years old, requires frequent costly repairs, or causes escalating energy bills, replacing it with a modern high-efficiency unit is often more cost-effective in the long run.
What brand of HVAC equipment do you install and repair?
We service, repair, and maintain all major heating and cooling brands. For new installations and upgrades, we work with industry-leading manufacturers to provide reliable, highly efficient equipment backed by solid warranties.
How frequently should I change my HVAC air filters?
Standard 1-inch air filters should be replaced every 1 to 3 months. If you have pets, allergies, or high dust levels in your home, checking and replacing them monthly helps protect indoor air quality and keeps airflow smooth.
