Question 1

Why won't my furnace turn on?

Accepted Answer

Start with the basics: thermostat set to heat with fresh batteries, furnace power switch on, and breakers not tripped. Beyond that, the usual culprits are a failed igniter, dirty flame sensor, or tripped limit switch — all quick diagnoses for a contractor. If you smell gas, leave the house and call your gas utility's emergency line.

Question 2

Why does my furnace keep turning on and off?

Accepted Answer

Short cycling is often a dirty flame sensor, restricted airflow from a clogged filter, or an overheating limit switch. It's inefficient and wears parts fast, so don't ignore it — a contractor can usually resolve it in one visit.

Question 3

Is a cracked heat exchanger dangerous?

Accepted Answer

Yes — a cracked heat exchanger can allow carbon monoxide into your home's airflow. Warning signs include soot around the furnace, a flickering burner flame, or headaches and nausea when the heat runs. This is a replace-the-furnace situation and a safety priority: call immediately.

Question 4

How often should I replace my furnace filter?

Accepted Answer

Check monthly during heating season; most 1-inch filters need replacement every 1–3 months. A clogged filter is the #1 cause of airflow-related furnace failures and frozen AC coils alike.

Question 5

My furnace is 18 years old and needs a repair. Should I fix it or replace it?

Accepted Answer

Furnaces typically last 15–20 years. At 18 with a major failure — especially a heat exchanger or control board — replacement usually makes more sense than another repair. Ask the contractor to assess both paths honestly during the visit.

Question 6

Do heating contractors offer free estimates?

Accepted Answer

Many independent contractors in our network offer free estimates. Confirm when you call so you know exactly what to expect from the visit.

Question 8

How does the Texas climate affect furnace & heating repair in Corpus Christi?

Accepted Answer

Dallas–Fort Worth (~2,800 CDD), Houston (~3,100 CDD), San Antonio (~3,200 CDD), and Austin (~3,100 CDD) form one of the densest cooling markets on earth. Hail season and heat waves drive replacements; winter cold snaps test heat pumps. That climate is exactly why local experience matters: contractors serving Corpus Christi size and troubleshoot equipment for these conditions every day. Texas cities require mechanical permits for replacements; the state licenses contractors through TDLR.
