FAQ

Questions Clovis homeowners ask before calling an HVAC Contractor.

Everything Clovis homeowners ask before repairing or replacing their AC — answered honestly, with over 25 years of experience in California’s Central Valley heat.

Most AC repairs in Clovis range from $150 to $2,500 depending on what failed. A capacitor replacement typically runs $200–$400. A refrigerant recharge with leak repair runs $400–$800. A compressor replacement runs $1,200–$2,500. Fresno’s extreme heat accelerates component wear faster than almost anywhere else in California — which is why catching problems early during annual maintenance consistently costs less than emergency repairs in July.
