What San Marcos Homeowners Ask About HVAC Contractor
How much does HVAC service typically cost in San Marcos?
HVAC service costs in San Marcos depend on the type of work. A standard tune-up runs $75-$150, while common repairs range from $150-$800. Full system replacements typically cost $5,000-$15,000 depending on system size (measured in tons) and efficiency rating (SEER). Higher-SEER systems cost more upfront but reduce energy bills by 20-40% annually. PlusCold AC Repairs provides free written estimates with itemized breakdowns so you can compare options.
How often should I schedule HVAC maintenance in San Marcos?
The industry standard is twice per year — once for heating (fall) and once for cooling (spring). Regular maintenance improves efficiency by 15-20%, extends system life by 5-10 years, and prevents 95% of breakdowns according to ACCA data. For San Marcos homes with pets, allergies, or older systems, quarterly filter changes are also recommended. PlusCold AC Repairs offers maintenance agreements that include priority scheduling and discounted rates.
What size HVAC system does my San Marcos home need?
System sizing requires a Manual J load calculation based on your home's square footage, insulation levels, window area, ceiling height, and orientation. A rule of thumb is 1 ton per 400-600 sq ft, but this varies significantly — an undersized system runs constantly and an oversized system short-cycles, both wasting energy and money. PlusCold AC Repairs performs proper load calculations for every installation in San Marcos to ensure correct sizing.
