Our Promise To You

At Assurance Heating & Air Conditioning, we believe your comfort matters. That’s why we put your needs first. When you call us for service, you can expect our technicians to arrive on time and in fully-stocked vehicles. We respect your family, your pets, and we clean up when we’re finished.

We’re here 24/7 for emergency service and, in most cases, we can get your HVAC system up and running in one day and on one trip. If you need a system replacement, we’ll work with you to find the product that best serves your needs and fits your budget. Our heaters and air conditioners are state-of-the-art, highly efficient systems that can save you money on energy bills.

HVAC Scheduled Maintenance

Whether your heater or air conditioner is an older model or a brand new upgrade, the best way to keep it in good condition is with regular preventive maintenance. We see many cases where expensive heating or air conditioning repairs and replacements could have been avoided had the system been inspected and maintained regularly.

Heating and cooling systems should receive regularly scheduled maintenance every year. With preventive care:

  • Your heat pump, furnace or air conditioner will last longer
  • HVAC systems will function at peak efficiency
  • There will be fewer repairs because small problems can be corrected early on
  • You’ll pay less in monthly energy costs
