Heating FAQs

Mission Air Conditioning & Plumbing is here to address your common heater questions with ease. Stay warm and comfortable when you trust our Houston HVAC technicians with your heating needs.

Who Should I Call When My Heat Is Not Working?

When your heat goes out, the best step is to contact a licensed HVAC technician, such as one from Mission AC. A technician has the tools and training to safely assess and repair your system. While it may sound tempting to troubleshoot on your own, heating systems (especially gas-powered ones) can pose safety risks if handled improperly.

If you suspect a gas leak or carbon monoxide issue, leave your home immediately and call your gas company or emergency services before contacting a heating professional.

Why Would Heat Suddenly Stop Working?

Heating systems can stop working without warning for a variety of reasons. In many cases, it’s due to something simple, like a tripped breaker, a dirty air filter or an issue with the thermostat. Other times, mechanical problems like a failed ignition system or blower motor could be to blame.

If you’ve checked the basics and the system still isn’t working, it’s time to call in a professional to get things back on track.

Why Is My House Still Cold With The Heater On?

It’s frustrating to have your heater running but still feel the chill indoors. This situation could mean your system is running inefficiently or struggling to distribute heat properly. Sometimes the heater is working fine, but external issues — like poor insulation or leaky ductwork — are allowing warmth to escape.

In other cases, the heater itself may be undersized for your home, or its components could be dirty or worn out. A professional can help determine if your system is underperforming or if your home needs improvements to retain heat more effectively.

Should I Get A Heat Pump Or A Furnace?

The answer to whether a heat pump is right for you will depend largely on your climate and heating priorities. If you live in a region with mild winters, a heat pump might be ideal since it provides both heating and cooling with excellent energy efficiency.

On the other hand, if you’re in an area with long, cold winters, a furnace will generally offer more powerful and reliable heating.

Other factors to consider include:

    • Your home’s insulation and size

    • Long-term energy savings vs. upfront costs

An HVAC expert from our team can help you evaluate your home’s needs and choose the best system for your comfort and budget.

What Does A Heating Tune-Up Include?

A tune-up is designed to keep your system running safely and efficiently through the colder months. It usually involves a detailed inspection and cleaning of system components, along with testing and calibration to catch problems early.

Typical tasks during a tune-up include:

    • Cleaning burners or heating elements

    • Checking thermostat function and safety controls

    • Lubricating moving parts and checking airflow

This type of service helps prevent unexpected breakdowns and ensures your system is operating at peak efficiency.

How Often Does A Furnace Need A Tune-Up?

To keep your furnace operating reliably, it’s recommended to schedule a tune-up at least once a year, preferably in the fall before cold weather sets in. Annual maintenance lets your technician spot small issues before they lead to major repairs, and it ensures your system is prepared for heavy use.

Skipping tune-ups might save you time in the short term, but it often leads to reduced efficiency, more wear and tear and unexpected breakdowns down the road. A yearly service is a smart investment in your home’s comfort and safety.
