Frequently Asked Questions About HVAC Companies

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

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:
  • Warm Air: The most noticeable sign is that the AC is blowing warm or not cool air.
  • Ice Buildup: Ice may form on the AC unit.
  • Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
  • Hissing or Bubbling Sounds: These sounds may suggest a refrigerant leak.
If you suspect low refrigerant, contact an AC repair specialist to fix the leak and add refrigerant.

How often should I have my HVAC system serviced?

Regular HVAC maintenance is essential for optimal performance, energy efficiency, and extending the lifespan of your system. It's generally recommended to have your system serviced once in the spring and once in the fall. Regular maintenance typically includes cleaning, inspections, and tune-ups of key components.

How do I choose the right HVAC contractor?

Selecting a qualified HVAC contractor is essential for a smooth and hassle-free HVAC project. Here’s what to look for:
  • Experience: Choose a contractor with extensive experience in the HVAC industry, especially in the type of service you need.
  • Licensing and Insurance: Verify that the contractor is properly licensed and insured.
  • Certifications: Look for NATE (North American Technician Excellence) certification, which indicates a high level of technical competency.
  • Reputation: Check online reviews and ratings to assess the contractor's reputation and customer satisfaction levels.
  • References: Ask for references from past customers and contact them to inquire about their experience.
  • Estimates and Quotes: Get written estimates or quotes from multiple contractors to compare pricing and services.

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.
