5 Common Winter HVAC Issues in Conroe Homes – And How Affordable Air Repairs Can Fix Them Fast
By Affordable Air Repairs | November 5, 2025
Winter in Conroe, Texas, might not bring blizzards, but those chilly nights dipping into the 30s°F can still put your HVAC system to the test. From frozen coils to skyrocketing energy bills, the season’s demands often reveal hidden problems in your heating setup. As a trusted local HVAC expert serving Conroe and The Woodlands since 2010, Affordable Air Repairs has seen it all—and we’re here to help you stay warm without breaking the bank.
Don’t wait for a full breakdown on the coldest night. In this guide, we’ll break down the top 5 winter HVAC issues, why they happen, and our affordable solutions. Remember: Regular maintenance now can save you hundreds in emergency repairs later!
1. Frozen Evaporator Coils: The Silent Freezer
The Problem: Your AC’s evaporator coils (used in heat pumps or dual systems) can freeze when indoor air is too dry or airflow is restricted. In Conroe’s variable winter humidity, this causes poor heating, ice buildup, and potential compressor damage—leading to uneven temps and higher bills.
Signs to Watch: Weak airflow, hissing sounds, or water leaks from the unit.
Affordable Fix: Our technicians perform a thorough coil defrost and cleaning for just $99. We’ll check refrigerant levels and replace dirty filters to prevent recurrence. Pro tip: Run a humidifier to maintain 30-50% indoor humidity.
2. Thermostat Malfunctions: Your Home’s “Thermostat Tantrum”
The Problem: Cold snaps expose faulty thermostats—batteries die, wiring loosens, or smart models glitch from power surges. In Conroe, where mornings can swing 20°F, this means your system cycles erratically, wasting energy and leaving rooms unevenly heated.
Signs to Watch: Inconsistent temperatures, constant clicking, or the unit won’t turn on.
Affordable Fix: We offer thermostat calibration or upgrade starting at $150, including programmable or WiFi-enabled models for energy savings up to 10%. Our same-day service gets you back in control before dinner.
3. Poor Airflow from Clogged Filters and Vents: The “Stuffiness Sneak Attack”
The Problem: Dust, pet hair, and Conroe’s occasional pollen overload filters, restricting airflow and forcing your system to overwork. This strains the blower motor and reduces efficiency by 15-20%, spiking your AEP bills during those few heating weeks.
Signs to Watch: Reduced warm air from vents, dustier rooms, or a burning smell from the unit.
Affordable Fix: A quick filter replacement and duct inspection for $75 ensures optimal flow. We recommend high-MERV filters for allergy-prone homes and can seal leaky ducts to boost efficiency by 20%.
4. Refrigerant Leaks: The Invisible Energy Thief
The Problem: Aging seals or corrosion cause refrigerant to leak, dropping system pressure and heating capacity. Texas winters might be mild, but low refrigerant means your heat pump works overtime, risking breakdowns and environmental harm (R-410A is regulated).
Signs to Watch: Hissing noises, warmer-than-usual air, or higher humidity indoors.
Affordable Fix: Our leak detection and recharge service starts at $250, using EPA-certified methods. We’ll patch or replace components affordably—avoiding the $2,000+ full system swap.
5. Dirty Heat Exchanger Cracks: A Dangerous Winter Wake-Up Call
The Problem: Cracks in the heat exchanger (common in older furnaces) allow carbon monoxide to escape, while soot buildup reduces efficiency. Conroe’s occasional freezes exacerbate expansion/contraction stress on metal parts.
Signs to Watch: Sooty residue, unusual odors, or flu-like symptoms (headaches, nausea).
Affordable Fix: Priority CO detector installation and exchanger inspection for $125—safety first! If cracks are found, we repair or replace efficiently, often under $800, with a 100% satisfaction guarantee.
