Frequently Asked Questions

You should schedule HVAC maintenance at least twice a year—once before cooling season and once before heating season. Regular tune-ups and inspections extend equipment lifespan and optimize efficiency. At Liberty Heat and Air, we recommend scheduling in spring and fall to prepare for Boise's temperature extremes.

A heat pump transfers heat rather than generating it, providing both heating and cooling in one system, while a furnace only heats by burning fuel or using electric resistance. Heat pumps are more energy-efficient in moderate climates. Liberty Heat and Air installs both water source and electric heat pumps for year-round comfort.

Proper AC sizing ensures your system cools efficiently without short cycling or excessive energy use. An oversized unit cycles on and off too frequently, while an undersized unit runs constantly and struggles to maintain temperature. Liberty Heat and Air performs detailed load calculations to optimize sizing for each property.

If your AC is under 10 years old and repair costs less than half the replacement cost, repair is usually best. Systems over 15 years old with frequent breakdowns or declining efficiency should typically be replaced. At Liberty Heat and Air, we provide honest diagnostics to help you make the most cost-effective decision.

Duct cleaning removes dust, allergens, and debris that restrict airflow and reduce indoor air quality. Clean ducts improve system efficiency, reduce energy costs, and help your HVAC equipment last longer. Liberty Heat and Air uses professional ventilation cleaning methods to restore optimal airflow throughout your home or business.

Modern heat pumps work effectively in Boise winters, especially electric and water source models designed for cold climates. They provide efficient heating down to very low temperatures and offer both heating and cooling. Liberty Heat and Air installs energy-efficient heat pumps engineered for Idaho's seasonal temperature swings.

Common causes include a tripped circuit breaker, dirty air filter, malfunctioning thermostat, or failed igniter or pilot light. Gas, electric, and water source furnaces each have specific failure points. At Liberty Heat and Air, we provide rapid diagnostics and repairs to restore heat quickly during cold Boise nights.

Rooftop units are self-contained systems combining heating and cooling in one cabinet, saving interior space and simplifying maintenance access. They require specialized service for blower motors, refrigerant handling, and gas or electric components. Liberty Heat and Air maintains and repairs commercial rooftop units across Boise-area businesses.

Emergency HVAC repair includes rapid response, expert diagnostics, and immediate fixes for heating or cooling system breakdowns. Technicians assess the problem, provide repair options, and restore comfort as quickly as possible. Liberty Heat and Air offers 24/7 emergency service for homes and businesses experiencing system failures.

AC units freeze due to restricted airflow from dirty filters, low refrigerant levels, or blocked coils. Freezing reduces cooling capacity and can damage the compressor if ignored. At Liberty Heat and Air, we diagnose the root cause and perform repairs to restore proper cooling performance and prevent future freeze-ups.

Most residential AC installations take one to two days depending on system complexity, ductwork modifications, and property size. Commercial installations may require additional time for rooftop units or large-scale systems. Liberty Heat and Air ensures proper installation with energy efficiency optimization and minimal disruption to your daily routine.

The biggest mistake is skipping regular maintenance, which leads to unexpected breakdowns, reduced efficiency, and shortened equipment lifespan. Many homeowners only call when problems occur rather than preventing them. Liberty Heat and Air recommends preventive tune-ups and inspections to catch issues early and keep systems running reliably year-round.
