General HVAC Questions
What does HVAC stand for?
HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems that regulate indoor temperature, air flow, and air quality in residential and commercial buildings.
How often should I have my HVAC system serviced?
We recommend twice per year: once in the spring for your air conditioning system, and once in the fall for your heating system. Regular maintenance helps extend the life of your unit, reduces energy costs, and prevents breakdowns.
How long do HVAC systems typically last?
Most HVAC systems last 12–15 years, but with regular maintenance, some can function well for up to 20 years. High-efficiency units may also have longer lifespans.
How do I know if I need a new HVAC system or just a repair?
Signs you may need a full replacement include frequent breakdowns, rising energy bills, uneven temperatures, and systems older than 12–15 years. We offer free second opinions and will always give honest advice.
Air Conditioning FAQ
Why is my AC running but not cooling?
This could be due to low refrigerant, a dirty air filter, a frozen evaporator coil, or a malfunctioning thermostat. Our technicians can diagnose and resolve the issue quickly.
How often should I change my air filter?
Change your HVAC filter every 1–3 months, depending on your household (pets, allergies, etc.). A clogged filter reduces efficiency and can cause damage to your system.
What’s the best temperature to set my thermostat in summer?
We recommend setting your thermostat to 76–78°F when you’re home, and 85°F when you’re away. A smart thermostat can help optimize settings for comfort and energy savings.
Heating FAQ
Do I need a furnace in Texas?
While Texas has mild winters, a furnace or heat pump is still important to maintain comfort and safety during cold snaps. Heat pumps are popular in our region due to their efficiency.
Why is my heater blowing cold air?
This could be due to a dirty filter, faulty pilot light, or a malfunctioning thermostat. Our team can diagnose and repair heating issues quickly.
What’s the difference between a heat pump and a furnace?
A heat pump transfers heat from outside to inside and can also cool your home. A furnace burns fuel to generate heat. Heat pumps are more energy-efficient in milder climates like Texas.
Indoor Air Quality FAQ
Why is indoor air quality important?
Poor indoor air can aggravate allergies, asthma, and other respiratory issues. We offer air purifiers, UV lights, humidifiers, and duct cleaning to help improve your home’s air.
How do I know if my ducts need cleaning?
Signs include visible dust around vents, a musty odor when the HVAC runs, and increased allergy symptoms. We recommend a duct inspection every 3–5 years.
Do air purifiers really work?
Yes! Whole-home air purifiers can remove up to 99% of airborne contaminants, including dust, pet dander, mold spores, and bacteria—helping you breathe easier.
Pricing, Maintenance & Scheduling
How much does a typical AC or furnace repair cost?
Most repairs range from $150 to $600, depending on the issue. We offer fair, transparent pricing and always get your approval before starting any work.
Do you offer maintenance plans?
Yes! Our Blue Wave Maintenance Plan includes two visits per year, priority scheduling, discounted repairs, and peace of mind. It’s the best way to protect your investment.
Do you offer financing?
Absolutely. We offer flexible financing options for system replacements and major repairs. Ask us during your estimate, and we’ll walk you through the process.
Can I get same-day service?
In most cases, yes. We offer same-day and emergency service in Leander, Cedar Park, Liberty Hill, Georgetown, and nearby areas.
