Frequently Asked Questions
What are my options for a more energy-efficient system?
To reduce your energy consumption and utility bills, consider upgrading to a high-efficiency furnace or air conditioning system. Newer models feature advanced technology that use less power to deliver consistently high-performance heating or cooling results. Our technicians can assess your current home and recommend the most energy-efficient options for your home.
Other upgrades also reduce energy consumption, such as:
- Ductwork insulation
- Sealing air gaps and leaks
- Programmable or smart thermostats
Why does my furnace make strange sounds?
Abnormal, persistent, or loud sounds from your furnace typically indicate an underlying problem. For instance, rattling or grinding noises are often associated with loose components, worn bearings, or other mechanical issues. Popping, banging, and other sounds point to problems with ignition system or heating components.
My AC isn’t cooling properly, what could be wrong?
Several issues can cause insufficient or uneven cooling, including:
- Faulty thermostats
- Refrigerant leaks
- Clogged air filters
- Ductwork damage
- Frozen evaporator coils
- Damaged blower motor
Should I repair or replace my current HVAC system?
Deciding between HVAC system replacement and repair depends mainly on the age and condition of your existing system. If it’s over 10 years old, experiencing frequent or recurring breakdowns, or consuming more energy than it should, a new model may offer better energy efficiency and be more cost-effective long-term.
