General HVAC FAQs
What HVAC services do you offer in South Texas?
We provide full-service residential HVAC support, including:
- Heating and air conditioning installation, repair, and maintenance
- Indoor air quality (IAQ) solutions
- Ductwork inspection, cleaning, and fabrication
- New Construction HVAC Installations
- Emergency HVAC repairs
How often should I service my HVAC system in South Texas?
We recommend servicing your HVAC system twice a year—once in the spring and again in the fall. Regular maintenance helps prevent breakdowns, reduces energy costs, and extends your system’s lifespan.
What types of filters are there? What type of filter do I need?
The type (and size) of filter you need depends on your HVAC system and indoor air quality needs. Common types include:
- Fiberglass Filters: Affordable but offer minimal filtration.
- Pleated Filters: Better filtration for dust, pollen, and pet dander.
- HEPA Filters: Capture 99.97% of particles; great for allergy-sensitive homes.
- Electrostatic Filters: Use static electricity to trap particles; some are washable.
For South Texas homes, pleated filters with a MERV rating between 8 and 11 are a solid choice for balancing airflow and filtration.
How often should I change my HVAC filter?
Replace standard disposable filters every 1 to 3 months. If you have a media filter, those should be replaced every 3 to 6 months, depending on the household. Clean filters support better airflow and indoor air quality.
Do you provide HVAC filters?
Yes! We can provide a replacement HVAC filter size during your cooling or heating maintenance visit—just let us know which size you need in advance. We also offer an online filter subscription service for convenient, scheduled deliveries.
Why is my home dustier than usual? Could it be my HVAC system?
A dusty home could be caused by dirty filters, leaky ductwork, or debris inside your HVAC system. Regular filter changes and duct cleaning can help significantly reduce indoor dust.
When should I replace my HVAC system in San Antonio?
In South Texas, where AC systems run almost year-round, HVAC units tend to wear out faster. Most air conditioners and heat pumps last about 10–15 years, while gas furnaces may last up to 20 years with proper maintenance. If your system is over 10 years old, requires frequent repairs, or no longer keeps your home efficiently comfortable, it may be time to consider a replacement. New models offer improved energy savings and better indoor comfort.

What size heating and cooling system is right for my South Texas home?
An accurate load calculation—completed by one of our comfort advisors—is the best way to determine the right size for your home. We’ll consider square footage, insulation, and other factors to determine the ideal-sized HVAC unit for your home.
What are the differences in the freons (refrigerants)?
Older systems often use R-22 and R-410A refrigerants, which have been phased out due to environmental concerns. Newer systems use R-454B or R-32, which have a lower global warming potential than R-410A and have been made the new industry standard for all systems.
If your AC still uses R-22, it’s a good idea to consider a system upgrade, as R-22 is no longer produced and becoming costly to replace.
How do I keep my drain line clean?
To keep your HVAC drain line clean—especially in South Texas, where humidity is high—flush it every 30–60 days with a cup of distilled vinegar or a solution of warm water and mild dish soap. This helps prevent algae and mold buildup, which can clog the line and cause water leaks. Also, during routine AC maintenance, ask your technician to clean and inspect the drain line for any blockages or damage.
Furnace FAQs
What is AFUE?
AFUE stands for Annual Fuel Utilization Efficiency. It tells you how efficiently a furnace converts fuel into heat. A higher AFUE rating means greater efficiency and lower utility costs.
What are the signs I need furnace repair in South Texas?
If your furnace is making odd noises, heating inconsistently, cycling too frequently, or driving up your energy bill, it’s time to give Beyer Boys a call. We’ll diagnose the issue and get your heat back on fast.
Why is my furnace blowing cool air?
Possible reasons your furnace is blowing cool or mildly warm air include:
- The thermostat is set to fan mode.
- The furnace hasn’t warmed up yet.
- A dirty air filter.
- An issue with the ignition system.
Let our techs diagnose the issue and provide an efficient fix for your furnace.
How often should I schedule a furnace tune-up in San Antonio?
We recommend a furnace maintenance tune-up once a year—ideally in the fall before you turn it on for the winter season. Tune-ups help keep your system safe, efficient, and ready for colder temperatures.
Why has my heating bill gone up?
High heating bills can be caused by drafty windows, dirty filters, outdated systems, or thermostat settings. Let us help you troubleshoot and improve your energy efficiency.
How can I make my furnace more efficient?
Improve insulation, seal air leaks, schedule regular tune-ups, and install a programmable thermostat. These steps all help lower energy bills and boost comfort.

Air Conditioning Frequently Asked Questions
What is SEER2?
SEER2 stands for Seasonal Energy Efficiency Ratio 2. It measures how efficiently an air conditioner or heat pump cools your home over a season. The higher the SEER2 rating, the more energy-efficient the system is. SEER2 is a newer standard that gives a more accurate picture of real-world performance than the old SEER rating.
How often should I schedule professional AC maintenance in Rockport, TX?
We recommend an AC tune-up every spring to prepare your cooling system for summer. Routine maintenance helps prevent surprise breakdowns and keeps your unit running efficiently.

Low refrigerant, thermostat issues, dirty coils, or clogged filters are common causes of an AC blowing warm air. Contact Beyer Boys for a fast, accurate diagnosis.
Why is my air conditioner freezing up in South Texas?

- Keep blinds closed during the day
- Schedule seasonal tune-ups

Heat Pump Frequently Asked Questions
What is HSPF2?
HSPF2 stands for Heating Seasonal Performance Factor 2. It measures how efficiently a heat pump heats your home over a season. Like SEER2 (the cooling efficiency rating), a higher HSPF2 rating means better energy efficiency. HSPF2 is part of updated testing standards that better reflect how systems perform in real homes.
What’s the difference between a heat pump and a gas furnace?
A heat pump uses electricity to move heat, working as both a heater and an air conditioner. In contrast, a gas unit (furnace) burns natural gas to generate heat. In South Texas, where winters are mild, heat pumps are often more energy-efficient and cost-effective because they don’t rely on fuel combustion. However, gas furnaces may still be preferred for their ability to provide very warm air quickly during cold snaps.
Can a heat pump replace my furnace and air conditioner?
Yes! A heat pump can function as both your heating and cooling system—exceptionally well in Southern Texas, where winters are typically mild.
How often should a heat pump be serviced in Marble Falls?
We recommend servicing your heat pump twice a year—once in the spring and once in the fall. Regular maintenance helps prevent unexpected breakdowns, improves efficiency, and ensures long-term performance.

Indoor Air Quality Frequently Asked Questions
What is indoor air quality (IAQ), and why is it important?
Indoor air quality refers to how clean and healthy the air inside your home is. Good IAQ is essential for your comfort and well-being, especially for people with asthma, allergies, or other respiratory conditions. At Beyer Boys, we help San Antonio families breathe easier with proven IAQ solutions.
What impacts indoor air quality in Southern Texas homes?
Around San Antonio, indoor air quality can be affected by everything from dust and humidity to how well your HVAC system is maintained. Common sources of poor IAQ include:
- Dust, pet dander, and pollen
- Mold and mildew
- Cleaning chemicals
- Tobacco smoke
- Poor ventilation
- Gas appliances
- Dirty ducts or clogged air filters
Is indoor air quality worse during winter?
Yes—during cooler weather in Texas, homes are sealed up to retain heat, which reduces airflow and traps indoor pollutants. That’s why winter in San Antonio, Rockport, Marble Falls, or a nearby area is an ideal time to schedule an IAQ inspection with Beyer Boys.
How do I know if my indoor air quality needs improvement?
If you’re experiencing more frequent allergy symptoms, musty odors, or excessive dust buildup in your home, it may be time for an IAQ evaluation. Our team can help you determine if an air purification system or other IAQ product will be best for your home.
