Heating & Air Conditioning (HVAC) in San Antonio, TX

Yes. Our San Antonio HVAC technicians are licensed for both under TACLB138286E, and in practice the two are hard to separate. In most homes here the furnace or air handler and the air conditioner’s indoor coil live in one cabinet in the attic, share a blower motor, breathe through the same ductwork and answer to the same thermostat. A technician who only knows one side would miss the cause half the time. It also means a heating visit is a chance to catch a cooling problem early, and the reverse. On a fall furnace tune-up we look at the drain and coil that gave you trouble in August; on a spring AC tune-up we note the blower wear that will matter in December.

The shoulder seasons: roughly March through early May, and again from late October into early December. The equipment is not under load, so you are not choosing a system in a hurry with the house at 88 degrees, and installation crews have more open days. Those are also the months when replacing the air conditioner and the furnace together makes the most sense, because the indoor coil and the furnace share a cabinet and doing both at once saves a second round of labor. We give you the options in writing, honored for 72 hours, and financing through Service Finance Company, LLC is available, subject to credit approval. Manager quality review applies to HVAC installs over $3,000.

Because that is when the equipment is finally asked to work at full effort after weeks or months of coasting. A capacitor that tested weak in March runs fine on 85-degree days and fails on the first 100-degree afternoon. A furnace ignitor that cracked in the attic heat is not discovered until the first night in the 30s. And everyone in Bexar County finds out at the same time, which is why the phones are busiest in the first 48 hours of any extreme. The way around it is to run the system under load before the weather does: a tune-up in spring for cooling and one in the fall for heating. Care Club members get both on an enrolled system, along with priority scheduling when the rush hits.

They do not have to be the same age, but they do have to work together, and an old furnace can hold a newer air conditioner back. The AC’s indoor coil sits on the furnace and depends on the furnace blower to move air across it. A 30-year-old single-speed blower cannot deliver the airflow a modern high-efficiency condenser expects, so you lose some of the efficiency you paid for and, in this humidity, some moisture control too. If the furnace is otherwise sound, we will say so and leave it alone. If it is on borrowed time, replacing it with a variable-speed furnace or an air handler matched to the newer coil is worth pricing; our San Antonio furnace installation page explains the options.
