What is SEER, and why does it matter?

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently your air conditioner or air-source heat pump cools over a season, taking into account cooling output divided by energy used. A higher SEER rating means better efficiency and lower energy costs over time.

Why might the SEER rating shown on an Energy Guide label differ from the SEER my dealer quoted?

The SEER number can vary because it depends on the entire HVAC system, not just the outdoor unit. The indoor components—like the evaporator coil, furnace or air handler—also affect the actual operational efficiency.

How often should my HVAC system be maintained or tuned up?

Annual preventative maintenance is highly recommended—for both air conditioning systems (usually before summer) and heating systems (typically before winter). Regular inspections and tune-ups help maintain efficiency, spot potential issues early, and prolong equipment life.

What does a typical HVAC maintenance visit include?

A professional maintenance visit from Crest Air will include inspection of system components, checking refrigerant levels, cleaning coils, examining fan motors and blower systems, checking electrical connections, inspecting drain lines, changing or cleaning filters, and testing overall system performance.

What type of air filter should I use, and how often do I need to change it.

  • Use a filter that matches your HVAC system’s blower specifications.
  • Standard disposable filters should be replaced at least once a month during heavy use.
  • Upgrading to a pleated media filter or media air cleaner can significantly improve air quality by trapping smaller particles more effectively.
  • Note: Some systems use proprietary or reusable filters, which may require special cleaning or replacement procedures—check your system manual or consult a technician.

How do I know if my HVAC unit is the right size for my home?

Sizing depends on several factors, including the square footage of your home, insulation levels, window placement, and ductwork design. Crest Air performs a load calculation (manual or software-based measurement) to determine the optimal size HVAC system for your specific home—this helps avoid issues such as short cycling or insufficient heating/cooling.

What is the typical lifespan of an HVAC system?

HVAC systems generally last around 10–15 years, though actual lifespans vary widely based on system type, frequency of usage, climate conditions, and how well maintenance is kept up. Regular maintenance can help extend life and reduce the likelihood of premature failure.

What should I do if my HVAC system is making odd noises or isn’t heating/cooling properly?

If your system is making strange sounds, blowing cool air instead of warm air (or vice versa), cycling frequently, or failing to maintain a comfortable temperature, it’s best to call a certified technician promptly. Addressing the problem early can prevent further damage, reduce repair costs, and avoid a full system breakdown. Crest Air offers both routine service and 24/7 emergency assistance.

Do you offer emergency HVAC repair services?

Yes—Crest Heating & Cooling provides emergency repair services outside of normal business hours, so you can get assistance when your system fails unexpectedly or at inconvenient times.

Will maintaining my HVAC system help me save on energy bills?

Absolutely. Regular maintenance helps keep systems running efficiently, improves airflow, prevents refrigerant or heat exchange problems, and reduces unnecessary energy usage. Clean systems run less strain-fully, drop fewer materials into duct systems, and overall use less electricity or fuel.

How can I schedule a maintenance check or request a repair service?

You can request service by calling Crest Air, or by using their online appointment request / service request form available on their website. After the request is submitted, a technician will reach out to arrange a convenient time to inspect or repair your HVAC system.

What HVAC brands does Crest Air install and service?

Crest Air is experienced with a variety of HVAC manufacturers, including Trane, Lennox, Goodman, Daikin, and Day & Night, and they handle installations, service, and repairs for many popular systems.
