Gas Furnaces

When it’s cold outdoors, and your Texas furnace breaks down, you need a professional heating and cooling contractor you can trust.

A well-maintained furnace does more than keep you warm. The HVAC filter traps dust, debris, and other particles to improve the indoor air quality (IAQ). Because your furnace uses ductwork, it can work with a whole-house humidifier (or dehumidifier) for a more comfortable surrounding.

AirStar repairs and services all your major furnace brands for homes and businesses in San Antonio, San Antonio, and surrounding areas.

Furnace Buying Tips

Keep these furnace tips in mind to create a healthy home for your family!

Efficiency pays off.

Most older furnaces have annual fuel utilization efficiency (AFUE) ratings in the low 80s. Replacing that old furnace with a high-efficiency furnace boasting an AFUE of 90 or higher will lower your energy bills significantly. These furnaces convert nearly all their fuel into heating.

What’s that sound?

Ask about decibel levels—how much noise the furnaces make when operating.

How’s that AC looking?

Replace your air conditioning unit and furnace together if they are both more than 10 years old—even if the AC still operates problem-free. You will save on installation costs and enjoy lower energy bills.

Create a whole-house HVAC solution

Consider installing a programmable thermostat that can help reduce your energy bills by 10 percent. Schedule to have your ductwork inspected to enjoy superior airflow. Adequate insulation in your attic and crawlspace will keep energy from escaping.

Furnace Installation and Replacement

AirStar will do all the necessary load calculations to accurately ensure the heating equipment we install in your San Antonio home fits like a glove.

We can help you choose the best furnace for your home and budget. Here are a few operating features to consider:

• Single-stage furnace
  These standard systems are either on or off. They are the least expensive to purchase upfront but can cost more to operate because they cycle more frequently.
• Two-stage furnace
  These furnaces have two settings. They can run at full power on super cold days or provide a comfortable temperature at a lower power setting on more moderate days.
• Variable-speed furnace
  Also known as a modulating furnace, these high-efficiency models can adjust the flame to the smallest increment, allowing them to run longer at a slower speed. Doing so gives you more control over the temperature and energy costs.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Just enter your current unit’s AFUE value and compare it to a newer, more efficient system.

Furnace Repair

You can expect an accurate quote and clear scope of the project before your AirStar technician begins any work. We repair and service gas, oil, and electric furnaces.

Here are some more common furnace issues we encounter:

• Clogged HVAC filter
  It seems obvious, but many a customer will forget to change their furnace filter. A clogged filter restricts airflow and allows contaminants to pollute the air you breathe. Follow your manufacturer’s recommendation on how often to change your furnace filter.
• Broken blower motor
  The blower motor pushes heat or cold air from your furnace or AC into the ductwork. A furnace that turns on and does not produce any warm air could mean a broken fan motor.
• Loose connections
  Our technicians will tighten the electrical connections, check the gas valve, check the fuel supply, and inspect the ignition system to ensure everything works correctly.
• Faulty thermostat
  Another one that’s easy to miss. Is the thermostat in the right setting? Does it need a new battery? Checking your thermostat first could avoid a service call.
• Drainage problems
  A puddle of water on the floor around your furnace could mean an issue with the condensate line or drain. If possible, remove the hose and give it a good flush to see if that solves the problem.

We offer 24/7 emergency HVAC repair services in San Antonio and surrounding communities to be there when you need us. Call us right away if you think there’s an issue with your furnace. 

Furnace Maintenance

AirStar recommends scheduling an annual tune-up for your furnace in the early fall, and one for your AC in the early so. Doing so ensures your HVAC equipment will operate efficiently when you need it the most.

Preventative maintenance for your furnace is similar to changing the oil and other fluids in your vehicle. It keeps it running longer. Here are a few tasks our technician will perform during a routine maintenance visit:

• Check the combustion chamber for any cracks that could lead to a carbon monoxide (CO) leak
• Check all connections to ensure everything is properly secured
• Remove dirt, corrosion, and soot from any component
• Check the flame setting and adjust it if necessary
• Check the connection between the furnace and air ducts
• Check the blower motor and adjust it if necessary
• Inspect the condensate drain
