Repair costs typically range from $150 to $2,000, depending on the complexity of the issue and the parts required. Larger repairs, such as fixing a blower or heat exchanger, may cost more.
Unit installation typically takes 4 to 8 hours, depending on the system and home size. More complex installations or replacements may take longer, sometimes up to a full day or more. Replacements can take closer to 8 due to the removal and disposal of the old unit.
