What Can We Help You Find?

Reducing energy bills without sacrificing comfort involves improving the efficiency of your HVAC system and making smart choices:

   – Invest in a programmable or smart thermostat to optimize temperature settings.

   – Seal windows, doors, and any gaps to prevent air leaks.

   – Upgrade insulation in your home.

   – Ensure your HVAC system is regularly serviced for peak performance.

   – Consider replacing older, inefficient systems with Energy Star-rated models.

It’s recommended to have your HVAC system serviced at least once a year. For optimal performance:

   – Air conditioning units should be serviced in the spring before the hot months.

   – Heating systems, whether furnaces or heat pumps, should be serviced in the fall before the cold season.

Regular servicing helps in early detection of potential issues, ensures energy efficiency, and prolongs the system’s lifespan.

While repairs can often fix issues, there are signs that indicate a system might need replacement:

   – The system is over 15 years old and frequently breaks down.

   – Energy bills are consistently rising without a change in usage patterns.

   – The system struggles to maintain desired temperatures or runs continuously.

   – You’re facing expensive repairs, especially if the cost approaches or exceeds half the price of a new system.

   – The system uses outdated refrigerants, like R-22.

Consult with an HVAC professional to evaluate whether a repair or replacement is more cost-effective.

The average lifespan of a residential HVAC system is typically between 15 to 20 years. However, this can vary based on the type of system, usage, and maintenance practices. To extend the lifespan of your HVAC system:

   – Schedule regular maintenance and tune-ups with a professional.

   – Replace air filters every 2-3 months or as recommended by the manufacturer.

   – Ensure the outdoor unit is clear of debris and has proper airflow.

   – Use a programmable thermostat to reduce unnecessary strain on the system.

There are several reasons why an air conditioner might freeze up:

   – Restricted airflow due to dirty filters or blocked return air ducts.

   – Low refrigerant levels, often caused by leaks.

   – Malfunctioning fan motors.

   – Dirty or blocked evaporator coils.

If you notice ice on your unit, turn off the AC to prevent further damage and call a professional HVAC technician. Regular maintenance can help prevent such issues.
