Heating & Air Conditioning Services

Whether you are installing or upgrading your HVAC system, looking for routine maintenance, or just need a simple repair, our team at Dial One Johnson Plumbing, Cooling & Heating can help.

Our services cover:

Air Conditioning Services

In our area, we are reliant on AC for home cooling nearly year-round. Luckily, our experienced technicians have seen just about every cooling system issue you can imagine. From regular maintenance to emergency air conditioning repair, we do it all.

To ensure you stay cool and comfortable all year long, we offer:

If something seems off with your home air conditioning unit and you’re not sure what the right course of action is, we’re happy to inspect your unit and help you make an informed decision.

Heating & Furnace Services

Since we use our HVAC systems in “cool” mode so often during the year, strange things can happen when you finally have to switch your system to heat. Whether your furnace pilot light won’t stay lit, your heat pump isn’t blowing warm air, or your system just needs a thorough cleaning, we can help you stay warm.

HVAC Maintenance Services

Routine preventative maintenance can help keep your HVAC system running efficiently while avoiding unnecessary repairs in the future.

Our maintenance services cover tasks such as:

  • Changing the air filters
  • Cleaning condenser and compressor coils
  • Checking the refrigerant charge
  • Cleaning the air handler
  • Cleaning furnace burners
  • Checking the electrical and safety systems

For the best results, your system should be inspected and maintained at least twice a year (once before cooling season and once before the heating season).


What is the best air conditioning brand?

There are many great air conditioning manufacturers out there, but at Dial One Johnson Plumbing, Cooling & Heating, we recommend and install Trane air conditioners. Trane air conditioners offer cost-effective, energy-efficient cooling with corrosion-free aluminum condenser coils. Available features like two-stage cooling, variable-speed compressors, and advanced sound insulation improve comfort and efficiency.

When should I replace my AC unit?

The older an air conditioner is, the more problematic and expensive it will be to operate. You should consider installing a new system when the current air conditioner is more than 10 to 15 years old, starts requiring frequent repairs, becomes inefficient (causing your energy bills to skyrocket), and/or has major issues like a failing compressor or coil leaks.
