Common NH Air Conditioning System Questions

  • It's important to choose the right size system for your home based on factors such as square footage, insulation, and climate. At GSMS, our Project Specialists will perform a load calculation to determine the appropriate size for your home.

  • New Hampshire homeowners should ask about the warranty on the system and what it covers. A longer warranty can provide peace of mind and protect against unexpected repair costs. At GSMS, we’re proud to offer our WOW Warranty where we will match the manufacturer warranty on our labor.

  • Whether you need to replace your central air conditioning system or repair it depends on several factors, including the age of the system, the frequency and cost of repairs, and the efficiency of the system.

    Here are some things to consider when deciding whether to repair or replace your central air conditioning system:

    Age of the system: Most central air conditioning systems have a lifespan of 10-15 years. If your system is nearing the end of its lifespan and requires frequent repairs, it may be more cost-effective in the long run to replace the system rather than continue to repair it.

    Cost of repairs: If the cost of repairs exceeds 50% of the cost of a new system, it may be more cost-effective to replace the system rather than continue to repair it.

    Efficiency: If your system is older and less efficient, it may be more cost-effective to replace it with a newer, more efficient model. A more efficient system can save you money on energy bills in the long run.

    Refrigerant: If your system uses R-22 refrigerant, which is being phased out due to environmental concerns, it may be more cost-effective to replace the system rather than continue to repair it with expensive R-22 refrigerant.

    Ultimately, the decision to repair or replace your central air conditioning system should be made with the help of a Service Specialist. We can provide you with a recommendation based on the age and condition of your system, the cost of repairs, and your budget and needs.

  • The lifespan of a central air conditioning system can vary depending on factors such as the quality of the equipment, how well it's maintained, and how frequently it's used. Generally, a well-maintained central air conditioning system can last between 10 to 15 years.

    However, some factors can impact the lifespan of a central air conditioning system. For example, if the system is not properly installed, if it's used excessively, or if it's subjected to extreme weather conditions, it may have a shorter lifespan.

    It's important to keep in mind that regular maintenance can help extend the lifespan of a central air conditioning system. We recommend to schedule annual maintenance checks with a professional HVAC contractor to ensure the system is in good working order and to address any potential issues before they become major problems.
