Frequently Asked Questions
What are the signs that my furnace needs repair?
A malfunctioning furnace can cause high energy bills, reduced comfort, and even safety risks. Common signs that your furnace needs repair include:
- Uneven temperature distribution
- Insufficient heating
- Frequent cycling
- Abnormal sounds
- Unpleasant odors
My HVAC system is making strange noises, is that a problem?
Abnormal sounds from your HVAC system typically indicate underlying mechanical issues or problems. Loose duct connections, screws, and other parts may cause rattling or vibrating sounds. Worn-out blower fan belts or motor bearings may cause squealing, screeching, or grinding, and these problems require prompt attention to prevent further damage and costly repairs. Whistling or hissing can signal restricted airflow or ductwork leaks.
My energy bills have been high, can you help me improve efficiency?
High energy bills may stem from inefficiencies with your HVAC system. Outdated or worn systems gradually lose efficiency, and they usually can’t match the efficiency of a modern AC, furnace, heat pump, or other type of HVAC unit. Upgrading to a high-efficiency system can reduce your energy bills. If your system is relatively new and in good condition, these strategies may also improve heating and cooling performance while lowering energy bills:
- Replacing air filters every 30 to 90 days
- Sealing or repairing ductwork
- Installing a programmable or smart thermostat
- Upgrading your home’s insulation and fixing air leaks
How long does HVAC installation take?
The time required for HVAC installation depends on the system type, installation complexity, and other factors. Standard installations usually only need one day, but others may take longer — for example, installing or replacing ductwork may require significantly more labor.
What are the benefits of upgrading to a high-efficiency HVAC system?
High-efficiency central ACs, furnaces, heat pumps, and other HVAC systems offer several benefits, such as:
- Lower energy consumption
- Reduced utility bills
- Consistent indoor temperatures and improved comfort
- Eligibility for rebates and tax credits
