AC Installation & Replacement

Sometimes repair is simply not a cost-effective option and the air conditioner must be replaced. You should consider AC replacement if:

  • Your current AC unit is over 10 or 15 years old
  • It is operating inefficiently, with excessively-high cooling costs
  • It requires frequent repairs
  • Or it has major problems, like a compressor failure or leaking condenser

At Dial One Johnson Plumbing, Cooling & Heating, we offer complete installation services for a variety of AC equipment, including central air conditioners, heat pumps, ductless mini-splits and packaged systems. We will keep you informed through every step of the process, from load calculation and sizing, to selecting the system and performing the final installation.

Preventive AC Maintenance

Routine maintenance can help you to prevent unnecessary AC repairs, extend the life of your system and minimize your cooling costs. Some things you can do yourself, such as changing the air filter monthly or keeping the area around the condenser clean. Others require an HVAC professional, including:

  • Thoroughly cleaning the evaporator and condenser
  • Checking the refrigerant charge
  • Cleaning the air handler and blower fan
  • Lubricating motor bearings and pulleys
  • Cleaning the condensate drain
  • Inspecting the electrical and safety systems

At Dial One Johnson Plumbing, Cooling & Heating we can handle all your air conditioning maintenance needs, according the manufacturer’s recommendations and schedule. With one or two maintenance appointments a year, you can help keep your system running efficiently and protect its warranty.

Duncanville Heating Repair

For most of the year, you don’t have to worry about heating your home. When winter comes, however, temperatures can drop quickly. If you find out that your heater isn’t working when it gets really cold, we can respond to your issue promptly. We’re available 24 hours a day, seven days a week. We have the tools, skills, and parts to fix:

  • Broken pilot lights
  • Malfunctioning thermostats
  • Obstructed blowers
  • Smoking or burning smells
  • Mold in your furnace
  • Inconsistent heating
  • Heaters that won’t turn off

In most cases, we’re able to solve these problems with minimal hassle or cost. There are some circumstances, however, where we may recommend you replace a part instead of repairing. That’s either because the cost of a repair will be too high or the component is damaged beyond repair. We’ll always try to present you with the most cost-effective option.

Heating Installation & Replacement

An expert installation or replacement is recommended if you want your new heating system to function efficiently and reliably for as long as possible. At Dial One, we can handle your project no matter how big your property is. We can install all types of furnaces, heat pumps, and other heating components. Here’s what you can expect when you hire us for this type of project:

  • Punctual arrival
  • High-quality workmanship
  • Respectful service
  • Flexible financing
  • Quick responses to questions and requests

All the professionals at our company are committed to excellent customer service at every step of the installation or replacement process. Once your installation is complete, we can show you some regular maintenance duties you can perform to keep your system running optimally. These duties include cleaning filters, testing the thermostat, and generally being aware of how your heater is operating.

Heating Maintenance & Annual Tune Ups

Our highly skilled technicians go through extensive heating system training. That means they can keep your major heating components, like your furnace, boiler, or heat pump, in tip-top condition. We’re also ready to maintain your:

  • Pressure relief valves
  • Back flow restrictors
  • Pressure regulators
  • Control valves
  • Heat exchanger units
  • Thermostats
  • Ducts and vents
  • Pipes

By keeping all of the components in your heating system in good condition, you can drastically reduce the chances of a part breaking when you need it to work most. We recommend that you schedule heating system maintenance at least twice a year. We can check your heating and cooling system at the same time, saving you lots of money in the long run.
