How do I know if I need HVAC repair or full replacement?

Generally, if your system is under 10 years old and the repair cost is less than 50% of replacement cost, repair makes sense. Systems over 15 years old or requiring major component replacements are often better candidates for full replacement. We'll give you an honest assessment.

How long does HVAC installation take?

A standard residential HVAC replacement typically takes 4–8 hours. Complex installations or ductwork modifications may take longer. We'll give you an accurate time estimate before beginning any work.

Do you offer emergency HVAC repair?

Warning Signs

Signs Your HVAC System Needs Attention

Weak or No Airflow

If rooms aren't cooling or heating evenly, or airflow from vents feels weak, your system may have a failing blower, blocked ducts, or a failing compressor.

Spiking Energy Bills

A sudden increase in utility bills without a change in usage often means your HVAC is working overtime due to a failing component or refrigerant leak.

Strange Noises

Banging, grinding, squealing, or rattling from your HVAC unit indicates failing parts that need attention before they cause further damage.

System Over 15 Years Old

Older HVAC systems lose efficiency significantly over time. If yours is 15+ years old, replacement may cost less than continuing repairs and will dramatically lower your energy bills.
