Everything You Need to Know
How do I know if my HVAC system needs repair?
If your AC or furnace is blowing weak air, making strange noises, or causing your energy bills to spike, it’s likely time for repair. Uneven temperatures, short cycling, or no airflow at all are also signs something’s wrong. Don’t wait until it breaks—call us at the first sign of trouble for quick and honest help.
How often should HVAC systems be serviced?
To keep your heating and cooling systems running smoothly, they should be serviced at least once a year. We recommend spring for air conditioning maintenance and fall for furnace or heat pump tune-ups. Regular service helps prevent costly breakdowns, extends equipment life, and improves energy efficiency.
Should I repair or replace my HVAC unit?
If your system is over 15 years old, breaking down frequently, or causing rising utility bills, replacing it might be the better investment. However, if the issue is small and the unit is still in good shape, a repair may be all you need. We’ll always give you honest advice so you can make the right call for your home and budget.
Do you offer both residential HVAC repair and installation?
Yes! We provide complete HVAC services for homeowners—from air conditioning and furnace repairs to full system installations. Whether your unit needs a quick fix or a full upgrade, we’re ready to help with expert solutions and friendly service.

What should I do if my furnace isn’t heating properly?
If your furnace isn’t blowing warm air or keeps shutting off, check your thermostat settings, change the filter, and make sure the power switch is on. If it still doesn’t work, call us. We’ll inspect the unit, find the issue fast, and get your heat back on without delay.
