Heating and cooling questions, answered straight

No. AirFlow HVAC is a free referral service. We connect you with up to three independent local HVAC professionals, and you work directly with the pro you choose. We do not employ technicians, own trucks, or perform the work ourselves.

The main factors are what failed and how hard it is to reach, the age and type of your equipment, parts needed, whether ductwork or refrigerant work is involved, and timing — after-hours calls typically carry an emergency rate. We do not quote prices sight unseen; a pro assesses your specific job.

No heat in freezing weather, no cooling during extreme heat, a burning smell from vents, or a gas odor are emergencies — call right away. First, shut off the system for electrical smells, and if you smell gas, leave the house and call your gas utility before anyone else. We never promise a specific arrival time we cannot control.

Repair when the system is under about 10 years old and the failure is a single replaceable part — a capacitor, contactor, igniter, or blower motor. Consider replacement when the unit is past its expected service life, the heat exchanger or compressor has failed, or repairs are becoming a yearly habit.

Safe DIY covers replacing the air filter, checking thermostat batteries and settings, resetting a tripped breaker, and clearing leaves and debris from around the outdoor unit. Call a pro for anything involving refrigerant, gas lines, or internal electrical work — those carry real safety and legal risks.

The most common HVAC cause is a system losing efficiency — a clogged filter or coil, failing components, leaky ductwork, or refrigerant running low. Start by replacing the filter and checking for obvious issues like blocked vents; if the bill stays high, a pro's tune-up finds what you cannot see.

A tune-up catches worn parts before they fail, keeps airflow and refrigerant charge where they should be, and often restores efficiency that has drifted down. Most manufacturers also expect documented maintenance to keep equipment warranties in force.

No — refrigerant work is pro-only. Handling, adding, or recovering refrigerant requires certified equipment and EPA certification, and venting it to the atmosphere is illegal. If your system is low on refrigerant, it also has a leak that a pro needs to find and fix.

We connect homeowners with independent HVAC professionals across all 50 states — from major metros to smaller cities. Enter your ZIP on any location page to check coverage in your area.

Major installations and gas or electrical changes usually require a permit, and requirements vary by city and county. The pro you hire handles the permit paperwork as part of the job — confirm this before work starts so inspections and warranty coverage stay valid.
