Frequently Asked Questions

It is $16 a month for one unit, and $14 a month for each additional unit at the same address.

Two tune-ups a year, one in spring and one in fall, and 15% off parts and labour on every visit. The discount does not apply to replacements or new units.

A spring or fall tune-up on its own is $59.

Monday to Friday, 7:30 AM to 5:00 PM. Saturday is by appointment or for emergency service. We are closed Sunday.

Tyler, Lindale, Bullard, Flint and Whitehouse, and roughly a 15 to 20 mile radius of Tyler.

Yes. Walk-in coolers and freezers, reach-ins, and the controls that run them, alongside the heating and cooling side.

Low airflow from a clogged filter or coil, low refrigerant from a leak, a failed capacitor or a frozen coil are the common causes, and each looks the same from the thermostat.

Ice on the line or coil means the coil is running too cold — usually restricted airflow or low refrigerant. Turning the system off to thaw it is the first step; finding the cause is the second.

From a load calculation on the house — insulation, windows, orientation and ductwork — not from the old unit. An oversized system cools the air before it can remove the humidity and wears itself out cycling.

The indoor coil and outdoor unit are matched to each other for capacity and refrigerant. Replacing one and not the other usually costs efficiency and can void the manufacturer's rating.

A safety control is stopping it — a flame sensor, pressure switch or limit switch. Each one shuts the furnace down for a different reason, which is why the ignition sequence is watched rather than guessed at.

No. A cracked exchanger can let combustion gases into the air the furnace circulates, and the answer is replacement of the exchanger or the furnace. We show you the crack before recommending either.

It vents through plastic pipe rather than the chimney and produces condensate that has to drain, so the venting route and a condensate line are part of the job.

Not always, but the ducts have to move the airflow the new furnace needs. Undersized returns or leaking trunks are corrected while the equipment is being changed.

Cooling before the warm season and heating before the cold one, so a worn part is found while the system is not under load rather than on the first hot or cold week.

It depends on the filter and the house — pets, dust and how much the system runs. Checking it monthly and changing it when it is visibly loaded is the honest schedule.

Usually the ductwork — a crushed or disconnected run, a leaking joint, or a trunk too small for the distance. The equipment makes the air; the ducts decide where it goes.

Leaking ducts send conditioned air into the attic or crawlspace, and sealing them with mastic returns that air to the rooms. How much is lost is measured before the work, not assumed.

Rooms the central system does not reach, additions, garages, sunrooms and houses with no ductwork. Each head conditions its own zone, so each room can hold a different temperature.

Where it can throw air across the room rather than into a wall or a doorway, high on a wall with clearance around it, and where the line set can reach the outdoor unit without a long exposed run.

A low-grade filter, leaking return ducts pulling from the attic, or a return path that draws air from a dusty space. The source is found before a better filter is recommended.

Where winter air runs dry enough to cause static, cracked wood and dry skin, yes. Where summer humidity is the problem, a dehumidifier is the right device instead.

Not always. The thermostat has to match the equipment — single-stage, multi-stage or heat pump with backup — and many smart models need a common wire the existing wiring may not have.

Location. A thermostat in sun, in a draft, near a lamp or in a rarely used hallway reads its own spot, not the house. Moving it is often the whole fix.

Moisture from cooking, showers and breathing with nowhere to go. A tight house needs exhaust fans that actually vent outside and, often, a way of bringing fresh air in on purpose.

It brings fresh air in and pushes stale air out while passing the heat, and some of the moisture, from one stream to the other, so the house is ventilated without losing what it paid to condition.
