Hvac Repairs questions, answered by experts

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

A blocked vent is the most common cause of poor airflow in a duct system. However, there are many other reasons for inadequate airflow, including crushed or improperly sealed vents, a clogged filter, a poorly balanced HVAC system, a blocked condenser unit, or an undersized furnace or air conditioner. If you can’t identify any obvious issues in your system, contact an HVAC professional.

Costs depend on labor, part availability, furnace age, and the complexity of the repair.

It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.

If your furnace breaks then you’ll first need to check your thermostat settings and make sure they’re properly set and working. You should also double-check if you’ve accidentally tripped the breaker or blown a fuse. It’s best to call a professional for repairs, and you may want to turn your faucets onto a slow drip while you’re waiting, depending on how cold the outside temperature is.
