  • 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 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 refrigerant lines or evaporator coil.
  • 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 diagnose the issue and recharge the system.

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 usually the better overall choice.
  • Frequency and Cost of Repairs: If you've been having frequent or expensive 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 might have safety issues, such as carbon monoxide leaks. A new furnace offers enhanced safety features.
Consult with a reputable HVAC professional to assess your furnace and get recommendations.

What is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.
