Replace Systems That No Longer Perform

HVAC installation and replacement services in San Antonio for systems that have reached the end of their lifespan.

When your HVAC system in San Antonio struggles to maintain temperature, requires frequent repairs, or runs constantly without cooling or heating effectively, replacement becomes the more practical option. Systems that approach or exceed fifteen years of operation lose efficiency, use outdated refrigerants, and cost more to operate as components wear beyond economical repair. B & C Service Pros, LLC helps homeowners select new systems that match the square footage, insulation, and layout of their homes to avoid undersized units that run nonstop or oversized units that cycle too frequently.

We provide expert HVAC installation and replacement services in San Antonio, starting with a load calculation that accounts for ceiling height, window placement, and sun exposure to determine the correct system size. Our technicians remove old equipment, install new indoor and outdoor units, connect refrigerant lines, wire thermostats, and test airflow to verify that the system operates at rated capacity. We work with systems that use current refrigerants and meet efficiency standards that reduce energy use compared to older models.

If your system no longer keeps up with demand or repair costs add up to more than half the price of replacement, contact us to discuss options in San Antonio.

How we size and install new systems

Installation in San Antonio begins with measuring your home to calculate heating and cooling load, which determines the tonnage and BTU rating your system needs to maintain comfort without wasting energy. We inspect existing ductwork for leaks, blockages, or undersized sections that reduce airflow and efficiency. If ducts need sealing or modification, we address that before the new system goes in so it performs as designed from the start.

Once the new system runs, you notice rooms reach set temperature faster, humidity stays lower during summer, and the unit operates more quietly with fewer on-off cycles. We help customers choose the right system for their space, ensuring proper sizing, energy efficiency, and long-term performance. Your energy bills drop because the system no longer compensates for wear or inefficiency, and you avoid the frequent service calls that come with aging equipment.

We provide warranties on equipment and labor, walk you through thermostat programming, and explain filter replacement schedules so you know how to maintain the system after installation. Our technicians haul away old equipment and dispose of refrigerants according to environmental regulations, leaving your home ready to use the new system immediately.

What homeowners ask before replacing systems

Homeowners in San Antonio often want to know about costs, timing, and what affects system selection before committing to replacement.

How long does installation take?
Most installations take one full day for a straightforward replacement. If ductwork needs modification or electrical upgrades are required, the project may extend to two days.
What size system do I need?
System size depends on your home's square footage, insulation, ceiling height, and window area. We perform a load calculation to determine the correct tonnage so the system runs efficiently without short cycling.
When should I replace instead of repair?
You should replace when your system is over fifteen years old, uses R-22 refrigerant, or when repair costs exceed half the price of a new system. We provide both options with expected costs and lifespan.
What happens to my old system?
We remove your old indoor and outdoor units, recover refrigerant according to EPA guidelines, and haul away all equipment. You do not need to arrange disposal or recycling separately.
How much will my energy bill drop?
Energy savings depend on the age and condition of your old system, but homeowners typically see reductions of twenty to forty percent with new high-efficiency models. We provide estimated operating costs before installation.
