Key warning signs include: equipment older than 10–15 years, frequent costly repairs, rising electricity bills, uneven room temperatures, strange grinding or squealing noises, and recurring humidity problems. Our technicians provide honest evaluations on whether repair or replacement is more cost-effective.
