Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best HVAC systems for your needs.

Should I repair or replace my old furnace?

Here are some factors to consider when deciding whether to repair or replace your furnace:
  • Age: Furnaces typically last 15-20 years. If yours is significantly older, replacement is often the better overall choice.
  • Frequency and Cost of Repairs: If you've been having repeated repairs, replacing the furnace might be more cost-effective in the long run.
  • Energy Efficiency: Newer furnaces are significantly more energy-efficient, which can lead to lower energy bills.
  • Safety Concerns: Older furnaces can pose safety risks, such as carbon monoxide leaks. A new furnace offers enhanced safety features.
Consult with a trusted HVAC professional to assess your furnace and get recommendations.

What is an AFUE rating, and why is it important?

AFUE (Annual Fuel Utilization Efficiency) measures how effectively a furnace converts fuel to heat. A higher AFUE rating means greater efficiency and lower energy bills. The minimum AFUE for new furnaces is usually 80%, but modern furnaces can achieve AFUE ratings of 90-98%. Investing in a high-efficiency furnace can save money on heating costs over time.

How can I improve my home's indoor air quality?

You can take these steps to improve your indoor air quality (IAQ):
  • Regular Air Filter Replacement: Change or clean your HVAC system’s air filters regularly (every 1-3 months).
  • Professional Air Duct Cleaning: Have your air ducts cleaned by professionals every few years to eliminate dust, mold, and other contaminants.
  • Improve Ventilation: Ensure adequate ventilation in your home to bring in fresh air and exhaust stale air. Use exhaust fans in kitchens and bathrooms.
  • Control Humidity Levels: Use a humidifier or dehumidifier to maintain optimal humidity levels and prevent mold growth.
  • Clean Regularly: Dust and vacuum frequently to minimize airborne particles.
  • Avoid Smoking Indoors: Smoking indoors significantly reduces IAQ.
  • Use Natural Cleaning Products: Opt for natural cleaning products that don’t release harmful VOCs (volatile organic compounds).
  • Monitor Indoor Air Quality: Consider using an indoor air quality monitor to track pollutant levels.
If you have persistent IAQ issues, consult with an HVAC professional or an indoor air quality specialist for further assessment and solutions.

What should I look for when hiring an AC installer?

When hiring an AC installer, consider these key factors:
  • Experience and Expertise: Look for installers with experience and a good understanding of AC systems.
  • Licensing and Insurance: Make sure the installer is licensed and insured to work in your area.
  • Reputation and Reviews: Check online reviews and ratings from other customers.
  • Detailed Quotes: Get itemized quotes outlining all costs associated with the installation.
  • Warranties: Inquire about warranties on equipment and labor.
  • References: Ask for and check references from past customers.
  • Communication: Choose an installer who communicates clearly and promptly.
By carefully evaluating these aspects, you can choose a qualified and trustworthy professional for your AC installation.
