Extreme Heat Safety in Phoenix

Phoenix summers bring dangerous heat. When an air conditioner fails, indoor temperatures can rise quickly. Prioritize the safety of children, older adults, and those with health conditions. Know the signs of heat illness, such as dizziness, nausea, and confusion.

If your home becomes unsafe, go to a public cooling center, a friend's house, or a shaded area. Do not rely on fans alone when temperatures are very high. Plan ahead by knowing the locations of nearby cooling centers and having a backup plan for power outages.

  • Move to a cooled location if anyone feels unwell.
  • Call 911 for heat stroke symptoms like confusion or fainting.
  • Use wet cloths and cool baths if air conditioning is unavailable.
  • Never leave children or pets in a hot vehicle or home.
  • Check on neighbors who may be vulnerable during heat waves.

Utility Programs and Energy Assistance

Your electric utility may offer repair assistance, rebates, or payment plans. Contact them before hiring a contractor to understand your options. Some programs help with emergency repairs or replacements for qualifying households.

Ask the utility about any approved contractor lists or energy-efficiency requirements. They can also explain time-of-use rates that affect cooling costs. Keep your account number ready when you call.

  • Call your utility to ask about AC repair programs.
  • Inquire about rebates for efficient equipment.
  • Ask if they have a list of participating contractors.
  • Understand any income or eligibility requirements.
  • Request information on budget billing or payment assistance.

Permits and Local Building Rules

Many AC repairs and replacements in Phoenix require a permit. The contractor usually obtains it, but confirm this before work begins. Permits help ensure the job meets safety codes and may be required for warranty coverage.

  • Ask the contractor if a permit is needed for your repair.
  • Verify who will obtain and pay for the permit.
  • Contact your city or county building department for rules.
  • Keep a copy of the permit and inspection records.
  • Check that the contractor's license covers HVAC work.

Select a licensed Arizona HVAC contractor with experience in your type of system. Ask for their license number and verify it with the Arizona Registrar of Contractors. Get at least three written estimates that detail the scope of work.
