-
How long does a ductless mini-split system last?
If regularly maintained, a ductless mini-split can last 15 to 20 years. It’s one of the most durable HVAC systems, making it a popular and energy-efficient choice.
-
Are heat pumps loud when operating?
Heat pumps are quieter than many other heating and cooling systems, making them an ideal choice if you’re looking for a quiet system.
-
Should my heat pump be repaired or replaced?
Usually, a professional repair is sufficient to get a heat pump running properly again. However, if your system needs frequent repairs or is over 15 years old, your money is better invested in a new system. Our team can help you determine which option is best for your system and home.
-
Is a ductless mini-split system more efficient than a traditional HVAC system?
Yes. Due to their lack of ductwork, mini-split systems generally offer better energy efficiency than traditional HVAC systems.
-
When should I schedule ductless mini-split maintenance?
We recommend annual maintenance just before peak operating season. If you’re using your ductless mini-split for cooling, schedule a tune-up in the spring. Schedule maintenance mid-fall if you use your system for heating.
