Heating 

Keeping your home comfortable during winters and chilly spring nights means having a heating system that runs safely, efficiently, and reliably. Heating services cover furnace and heat pump repair, installation, replacement, and preventative maintenance. This page explains typical problems, what a professional diagnostic includes, how systems are sized and upgraded, and practical guidance on when to repair versus replace — all tailored to the climate and home styles common in the area. Schedule your heating service with Roadrunner Plumbing & Air.

Common Heating Problems And Service Types

In this region, many homes rely on heat pumps for year-round comfort, while some still use gas or electric furnaces. Typical heating services include:

  • Heater repair: fixing noisy blowers, uneven heating, short-cycling, or systems that fail to start.
  • Heat pump repair: addressing refrigerant leaks, defrost cycle issues, or outdoor unit failures.
  • Furnace repair: repairing ignition problems, pilot issues, or cracked heat exchangers.
  • Installation and replacement: removing old systems and installing new furnaces or heat pumps sized for your home.
  • Preventative maintenance: seasonal tune-ups to avoid breakdowns and extend equipment life.
  • Efficiency upgrades: installing variable-speed blowers, high-efficiency heat pumps, or smart thermostats.

Homes may face higher humidity and mild winters that favor heat pumps. However, occasional freezes and cold snaps make reliable heating and proper system sizing important.

What A Professional Diagnostic And Safety Check Includes

A thorough diagnostic identifies root causes and safety risks. Typical steps:

  • Visual inspection of indoor and outdoor units for damage or leaks.
  • Verify thermostat operation and control wiring.
  • Measure airflow, static pressure, and temperature splits.
  • Check refrigerant levels for heat pumps and test for leaks.
  • Inspect burners, ignition systems, and heat exchanger integrity on gas furnaces.
  • Test safety controls including limit switches, pressure switches, and carbon monoxide detectors.
  • Electrical inspection: voltage, amperage, and control board checks.
  • Combustion analysis where applicable to confirm safe, efficient fuel burning.

These diagnostics determine whether repairs, efficiency improvements, or full replacement provide the best long-term value.

Repair, Installation, Replacement, And Efficiency Improvements

Repairs can be straightforward fixes like replacing capacitors, sensors, or belts, or more complex work such as refrigerant recharge and coil replacement. When installing or replacing equipment, professionals evaluate:

  • Load and sizing: Proper sizing using Manual J load calculations ensures your new system matches your home’s heat loss and gain. Oversized units short-cycle and underperform; undersized units struggle during cold snaps.
  • System type: High-efficiency heat pumps are common for combined heating and cooling. For homes with natural gas lines, modern high-efficiency furnaces remain an option.
  • Ductwork condition: Leaky or undersized ducts reduce efficiency. Sealing and insulating ducts or upgrading to properly sized ductwork improves comfort and reduces operating costs.
  • Efficiency upgrades: Variable-speed motors, multi-stage compressors, electronic air cleaners, and programmable or smart thermostats enhance comfort and lower energy use.
  • Compatibility: New controls should be matched to HVAC equipment. Smart thermostats can learn occupancy patterns and save energy without sacrificing comfort.

Installation quality matters as much as equipment quality. Proper refrigerant charge, correct airflow, and professional calibration are essential for longevity and warranty compliance.

Preventative Maintenance And Scheduled Plans

Regular maintenance prevents unexpected breakdowns and preserves efficiency. A comprehensive maintenance visit typically includes:

  • Filter replacement or cleaning guidance.
  • Cleaning coils and outdoor unit debris removal.
  • Lubricating moving parts and tightening electrical connections.
  • Calibrating thermostat and verifying controls.
  • Inspecting heat exchangers and combustion components when applicable.
  • Checking condensate drains and condensate pump operation.

Scheduled maintenance plans often include seasonal tune-ups, priority service, and discounts on parts. For homes, a spring and fall check keeps both cooling and heating systems operating efficiently across temperature swings.

Warranty And Financing Overview

Most new HVAC systems come with manufacturer warranties covering parts for a set period and limited warranties on compressors or heat exchangers. Labor warranties vary by provider. Common warranty points:

  • Parts coverage typically 5 to 10 years or longer with registration.
  • Compressor or heat exchanger coverage may extend up to 10 to 20 years on some models.
  • Labor warranty lengths depend on installer policies.

Financing options can make replacement and high-efficiency upgrades more accessible. Typical offerings include installment loans, promotional no-interest periods, and energy-efficient financing programs. When evaluating options, consider monthly payment impact, loan term, and total interest relative to expected energy savings.

When To Repair Versus Replace

Deciding whether to repair a heater or replace it depends on several factors:

  • Age of the system: Furnaces and heat pumps older than 12 to 15 years are often less efficient and more prone to failures.
  • Frequency of repairs: Repeated visits in a single season suggest replacement is more cost-effective.
  • Repair cost vs replacement cost: A common rule is if a repair approaches 50 percent or more of the cost of a replacement, replacement is worth considering.
  • Energy efficiency: New systems can drop energy use substantially, especially if your current unit has low SEER or AFUE ratings.
  • Safety concerns: Any signs of a cracked heat exchanger or persistent carbon monoxide issues require immediate replacement for safety.
  • Comfort needs: If you need quieter operation, improved humidity control, or smarter controls, replacement may offer those benefits.

Heat pumps have unique considerations: refrigerant type (older R-22 systems), outdoor unit damage, and compressor failure can make replacement the practical choice.

Practical Tips And Long-Term Benefits

  • Replace standard filters regularly and consider high-quality pleated filters for better indoor air quality.
  • Use a programmable or smart thermostat to reduce runtime without sacrificing comfort.
  • Schedule maintenance before winter to avoid peak-season delays.
  • Consider combined heating and cooling upgrades to maximize year-round efficiency.
  • Properly sealed and insulated homes reduce heating demand and extend equipment life.

A well-maintained heating system improves comfort, reduces energy bills, and enhances safety. For homes, the right system and ongoing maintenance will handle the mild winters and occasional cold spells reliably while keeping indoor air quality and energy use under control.

    Chris, Roberto, and Joey from San Antonio Roadrunner Plumbing and Air were absolutely top-notch! They were professional, respectful, and got the job done at a very reasonable price. They replaced my AC coil, and now my air conditioner is working like new! Before finding them, I was stuck dealing with First American Home Warranty, and it was a nightmare. The contractor they sent out, Extreme Air Experts, was anything but expert. Total waste of time.I’m beyond grateful I found Roadrunner — they’ve earned my trust, and I’ll be using them for all my future HVAC needs. Highly recommend!

    I have used Roadrunner Plumbing for over 10 years and always get prompt, professional service and repairs. They communicate clearly and deliver a high quality result for a fair price. I wouldn’t trust anybody else. Here’s some pictures of the pressure reducing valve they replaced. The plumber Jonathan Evans showed up on time and was done in about an hour. First class operation and plumbers.

    Luis Rico with Roadrunner Plumbing & Air came out last week to evaluate a list of issues that needed some attention in my home. I was given 2 estimates with different options, which i appreciated. He was able to come back the following day with all the replacement items, and along with an assistant, Chance, completed all the work in about 4 hours. Luis & Chance were polite, knowledgeable and efficient, and I will be using Roadrunner again for any future plumbing needs. Thanks guys!😊
