System Maintenance & Service
What is a diagnostic fee?
A diagnostic fee is a flat rate that covers travel, inspection, and expert recommendations for your heating or cooling system.
What’s included in a system tune-up?
A system tune-up includes a full inspection, cleaning, and lubrication of key components to keep your system operating efficiently.
Why does my ductwork make a popping sound?
This often indicates undersized or improperly designed ductwork. We can assess your system and recommend adjustments to improve performance and reduce noise.
Why is regular maintenance important?
Like a car, your HVAC system needs routine maintenance to stay efficient and reliable. Neglecting maintenance can lead to breakdowns and higher energy costs.
System Performance & Noise
Is sound a concern with heating and cooling systems?
Yes. Modern systems are designed to run quietly, enhancing comfort without contributing to noise pollution. When shopping for a new system, compare sound ratings—especially if the unit will be near living or sleeping areas.
Why is my HVAC system freezing up?
Common causes include dirty filters, low refrigerant, or mechanical issues. You can check the filter and airflow yourself, but most cases require a professional inspection.
Equipment & Upgrades
How do I check if my HVAC system is under warranty?
Look for the manufacture date on the unit. If it’s under five years old, it might still be under warranty. We can confirm coverage with a quick inspection.
Should I replace my indoor unit when replacing the outdoor unit?
Yes. HVAC systems are designed to work in matched pairs for maximum efficiency, performance, and reliability. Replacing both ensures optimal function and includes full warranty coverage.
What is a zoning system?
A zoning system divides your home into separate areas with individual temperature control. It helps target comfort where it’s needed most and improves energy efficiency.
When should I consider zoning?
Zoning is ideal when installing a new HVAC system or building a new home. It’s especially useful in homes with varying comfort needs or rooms that are rarely used.
Safety & Fuel Types
What should I do if I smell gas?
Leave your home immediately. Call 911, your gas supplier, and a local HVAC contractor from a safe location. Do not use any electronics or light switches inside the house.
Could my gas furnace be causing headaches?
Possibly. This could be a sign of carbon monoxide exposure. Open a window and contact emergency services or a licensed technician to inspect your system.
Are gas furnaces safe and efficient?
Yes. Today’s gas furnaces are highly efficient and include safety features. Professional installation and regular maintenance are key.
Comfort & Efficiency
Which type of system provides the warmest air?
Fossil fuel systems like gas furnaces deliver the warmest air and tend to feel more comfortable than heat pumps.
Which fuel type is most affordable to operate?
Electricity and natural gas are typically more stable in pricing. Propane and oil fluctuate with market demand. A dual-fuel system offers flexibility and cost savings.
Which fuel type is least comfortable?
Heat pumps can feel less warm due to the lower air temperature they produce, which may feel cool in winter months. A humidifier can help improve comfort.
What are the benefits of installing a humidifier?
A humidifier reduces dry air issues like cracked skin, irritated sinuses, and damage to wood furniture. It also helps your home feel warmer, lowering heating costs.
System Design & Refrigerants
Why don’t you charge by the hour?
We use flat-rate pricing to offer transparent, upfront costs—so you’re never surprised by time or part-based charges.
What should I know about refrigerant changes?
Older refrigerants like R22 are being phased out due to environmental regulations. Newer systems use A2L, which is more efficient and eco-friendly. We can advise whether your current system needs an upgrade.
How does an air conditioner work?
Your AC moves indoor heat outside via refrigerant lines and condenser coils. It also removes moisture, reducing humidity and improving overall comfort.
