  • Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
  • Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.

If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.

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.

How do I choose the right size AC unit for my home?

Choosing the right AC unit size is essential for efficient cooling. An undersized unit won’t cool your home adequately, while an oversized unit will cycle on and off frequently, wasting energy and leading to premature wear and tear. A qualified HVAC technician will calculate the appropriate size AC unit for your home based on factors like:
  • Your home's square footage
  • Your local climate
  • Insulation levels
  • Window efficiency
  • Number of occupants
This calculation involves determining your home's cooling load, typically measured in BTUs (British Thermal Units). Don’t rely on estimates or guesswork; consult with an HVAC professional to ensure your new AC unit is properly sized for your specific needs.

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

The best temperature to set your thermostat in summer depends on your personal preferences and how much you’re willing to spend on energy costs. A general recommendation is to set your thermostat to 78°F (26°C) when you're home and awake. You can save energy by setting the thermostat higher when you're away or asleep.
