Frequently Asked Questions
When should I repair instead of replace my AC?
Repair may make sense for newer systems with isolated issues. Replacement may be better when the system is old, inefficient, unreliable, or facing a major component failure.
How often should HVAC systems be serviced?
Many homeowners schedule AC service before summer and heating service before colder weather. Regular maintenance can catch small issues before peak-season breakdowns.
What should be included in an HVAC replacement quote?
A quote should include equipment model, efficiency rating, sizing method, duct or thermostat work, permits, warranty, labor scope, disposal, and payment terms.
Why are some rooms hotter than others?
Uneven comfort can come from duct issues, insulation, sun exposure, poor airflow, equipment sizing, or thermostat placement. A good HVAC company should diagnose before guessing.
Should I get a second opinion before replacing my system?
Yes, especially for expensive replacements. A second opinion can confirm whether replacement is necessary and whether the proposed system is sized correctly.
