Q & A

Do you offer maintenance plans?

Yes, we offer seasonal tune-up programs designed to keep your HVAC system running at its best year-round. Ask us about our Rocket Air maintenance plan!

How long does an HVAC repair usually take?

Most repairs are completed in under two hours. If we need to order a part, we’ll explain the timeline and keep you updated.

Do you service both heating and cooling systems?

Yes! We work on air conditioners, furnaces, heat pumps, and packaged HVAC systems. Whether it’s hot or cold outside, we’re ready.

How long do HVAC systems typically last?

The lifespan of an HVAC system varies based on its type, brand, and usage, but on average, you can expect a well-maintained system to last about 15-20 years. Regular maintenance can significantly extend your system’s life.

Can I perform any maintenance on my HVAC system myself?

Yes, there are several maintenance tasks you can perform yourself, such as changing or cleaning air filters every 1-3 months, checking and clearing the AC condensate drain line, and keeping the HVAC unit free of debris. However, more technical tasks should be left to professionals.

What does SEER mean?

SEER stands for Seasonal Energy Efficiency Ratio. It measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output divided by the total electric energy input during the same period. A higher SEER rating means greater energy efficiency.

Why is my HVAC system freezing up?

This can happen for several reasons including restricted airflow, low refrigerant levels, or issues with the thermostat. If your system is freezing up, it’s advisable to turn it off and call a professional for a thorough inspection.

What is the difference between a heat pump and a traditional furnace?

A heat pump provides both heating and cooling by moving heat in or out of your home, depending on the season. A traditional furnace, on the other hand, generates heat by burning fuel or using electric resistance. Heat pumps are generally more energy-efficient and cost-effective in mild climates.

What should I consider when replacing my HVAC system?

Consider factors like the size of your space, the efficiency of the system (SEER and AFUE ratings), your budget, and the climate in your area. It’s also crucial to choose a reliable service provider for proper installation.

How can I save money on my HVAC operating costs?

Improving your system’s efficiency with regular maintenance, upgrading to a high-efficiency system, using programmable thermostats, and ensuring your home is well-insulated are effective ways to reduce operating costs.

What is an HVAC zoning system?

An HVAC zoning system allows you to divide your home into different zones, each controlled independently with its thermostat. This system can significantly improve comfort and efficiency by heating or cooling only the areas that need it.

What does AFUE stand for, and why is it important?

AFUE stands for Annual Fuel Utilization Efficiency, and it measures a gas furnace’s efficiency in converting fuel to energy. A higher AFUE percentage indicates a more efficient furnace, with less wasted fuel.

How can I improve the air quality in my home?

Improving indoor air quality can be achieved by regularly replacing HVAC filters, installing air purifiers or cleaners, maintaining proper humidity levels, and ensuring adequate ventilation to reduce pollutants and allergens.

Why is my HVAC system so noisy?

Noise issues may be due to loose parts, debris in the vents, issues with the fan or blower, or an aging system that needs repair or replacement. It’s best to have a professional diagnose and remedy the problem to prevent further damage.

What are ductless mini-split systems?

Ductless mini-split systems are HVAC systems that do not require ductwork. They consist of an outdoor compressor/condenser and one or more indoor air-handling units. These systems are ideal for room additions, small apartments, or spaces where installing ductwork is impractical.

What should I do if my HVAC system starts leaking water?

If your HVAC system starts leaking water, turn it off immediately to prevent damage to your home. A common cause is a clogged condensate drain line or a damaged drain pan. Check your air filter as well — a dirty filter can cause coils to freeze and later leak.

It’s best to contact a licensed HVAC technician to inspect and fix the issue properly. Ignoring the leak can lead to mold growth, water damage, or even system failure.

How does humidity affect my HVAC system's efficiency?

High humidity levels can make your HVAC system work harder to cool your home, reducing efficiency and comfort. Using dehumidifiers and maintaining your AC properly can help manage humidity levels and improve system performance.

What is the best temperature to set my thermostat in winter?

The ideal thermostat setting for winter is around 68°F while you’re at home and lower when you’re asleep or away from home. This helps to save on heating costs while maintaining comfort.

How often should I have my air ducts cleaned?

Air ducts should be inspected and cleaned every 3-5 years to remove dust, debris, and potential mold. This improves your HVAC system’s efficiency and the quality of your indoor air.

Can installing a smart thermostat save money?

Yes, installing a smart thermostat can lead to significant savings on your energy bills. These devices allow for more precise control over your HVAC system, learning your schedule and preferences to optimize heating and cooling patterns accordingly.
