Air Conditioning Services Including Repair and Installation in Tucson AZ and Surrounding Areas
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.
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.
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.
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.
- 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.
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.
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.
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.
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.
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.
