Furnace & Heating Questions
Why is my furnace not heating properly?
This can happen for several reasons: dirty filters, thermostat issues, ignition problems, airflow blockages, or failing internal components. We offer fast diagnosis and repair to get your heat back on quickly.
How often should I replace my furnace filter?
Most homes should replace furnace filters every 1–3 months, depending on:
- Pet presence
- Allergies
- Filter type
- Home dust levels
Regular filter changes improve efficiency and extend the life of your system.
How long does a furnace last?
On average, 15–20 years—depending on the model, usage, and how well it’s maintained. If your furnace is older, noisy, or constantly needing repairs, it may be time for a replacement.
Do you install new furnaces?
Yes. We provide expert furnace installation with transparent recommendations based on your home size, budget, and comfort goals.
Air Conditioning Questions
Why is my AC blowing warm air?
Common issues include low refrigerant, dirty coils, clogged filters, or a failing compressor. Our technicians can identify the cause and repair it quickly.
How long does an air conditioner last?
Most AC units last 12–15 years. Regular maintenance can extend lifespan and prevent breakdowns during peak summer temperatures.
Do you offer AC maintenance?
Absolutely — AC maintenance helps keep your system efficient, prevents breakdowns, and lowers energy costs. We perform inspections, clean coils, check refrigerant levels, and ensure everything is running safely.
Do you install new AC systems?
Yes. We install high-efficiency air conditioners and can help you select a unit that fits your home and budget.
