Air Conditioning Services FAQs

 Your HVAC system should be professionally serviced twice a year — once in the spring for air conditioning and once in the fall for heating. Regular maintenance helps prevent breakdowns, improves efficiency, and extends equipment life. 

Most standard filters should be changed every 1–3 months depending on:

• Pets in the home 
• Allergies 
• Dust levels 
• System usage 

A dirty filter restricts airflow and can damage your system.

Common causes include:

• Dirty air filters 
• Low refrigerant 
• Blocked airflow 
• Dirty evaporator coils 
• Blower motor issues 

Turn the system off and contact a professional before damage occur

Possible reasons include:

• Low refrigerant 
• Dirty coils 
• Thermostat problems 
• Clogged drain line 
• Electrical issues 
• Dirty filters 

If your system is blowing warm air, it should be inspected promptly.

Recommended settings:

• Summer: 72–78°F 
• Winter: 68–72°F 

Programmable or smart thermostats help improve comfort and lower energy costs.

Average lifespan:

• Air conditioners: 10–15 years 
• Heat pumps: 10–15 years 
• Furnaces: 15–20 years 

Regular maintenance can significantly increase system life.

Usually caused by:

• Clogged condensate drain line 
• Dirty drain pan 
• Frozen evaporator coil 
• Improper installation 

Drain line clogs are one of the most common HVAC service calls.

Yes. Maintenance helps:

• Lower energy bills 
• Prevent major repairs 
• Improve indoor air quality 
• Keep manufacturer warranties valid 
• Extend equipment lifespan 

Skipping maintenance often leads to costly repairs later.

Uneven temperatures may be caused by:

• Poor airflow 
• Duct leaks 
• Dirty filters 
• Improper system sizing 
• Insulation issues 
• Closed vents 

A professional inspection can identify the cause.

SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating, the more energy-efficient the system is. Higher efficiency systems can reduce monthly utility bills. 

Replacement may be the better option if:

• Your system is over 10–15 years old 
• Repairs are frequent 
• Energy bills are rising 
• Major components have failed 

A professional can help compare repair costs versus replacement savings.

Different odors can indicate:

• Mold or mildew in the system 
• Burnt wiring 
• Dirty filters 
• Dead animals in ductwork 
• Drain line bacteria buildup 

Strange smells should never be ignored.

You can improve efficiency by:

• Changing filters regularly 
• Scheduling maintenance 
• Using a programmable thermostat 
• Sealing duct leaks 
• Improving insulation 
• Keeping outdoor units clean

Typical HVAC maintenance includes:

• Checking refrigerant levels 
• Cleaning coils 
• Inspecting electrical components 
• Cleaning drain lines 
• Checking airflow 
• Testing thermostat operation 
• Inspecting motors and capacitors 
• Measuring system performance

Common noises and causes:

• Banging: loose parts 
• Squealing: belt or motor issues 
• Clicking: electrical problems 
• Rattling: loose panels or debris 

Unusual sounds usually mean service is needed.

Yes. Dirty ducts can:

• Reduce airflow 
• Spread dust and allergens 
• Lower efficiency 
• Affect indoor air quality 

Duct inspections are important, especially in older homes.

Signs include:

• Warm air from vents 
• Ice buildup on lines 
• Hissing sounds 
• Longer cooling cycles 
• Higher electric bills 

Low refrigerant usually means there is a leak.

Local companies often provide:

• Faster response times 
• Personalized service 
• Knowledge of local climate conditions 
• Ongoing customer relationships 
• Better long-term support 

Family-owned HVAC companies often build their reputation on trust and honest service.
