Lancaster, TX AC Repair

Your air conditioner works hard all year round because let’s face it, this is Texas. Before you’re caught in the sweltering heat without an AC, check in with your cooling unit to ensure it’s working as well as it could be. Usually your air conditioner will show signs of wear and tear. By catching this early, you can save yourself money and comfort by avoiding costly repairs.

Common signs your air conditioner needs repair include:

  • Air conditioner is blowing out warm air

  • The unit won’t turn on

  • The thermostat isn’t working

  • AC frequently cycles on and off

  • AC is making strange, screeching noises

  • You smell gas or foul odors

Our Lancaster AC repair professionals have extensive training, the latest industry certifications, and experience with all common types of cooling equipment. And with our 24-hour emergency AC repair service, you can rest assured someone is always available to help.

Lancaster AC Replacement & New AC Installation

The average lifespan of an AC unit is 15 to 20 years. However, how well you maintain the unit, how much you use it, and the weather conditions in your area all effect how long it lasts as well. If you find yourself spending more money trying to fix your AC than it would cost to replace it, it’s time for a new AC.

What you get from our AC replacement and installation services:

  • Remove the old AC unit, if necessary

  • Perform a cooling load calculation

  • Select an appropriate system

  • Install the condenser unit, air handler, refrigerant lines and electrical lines

  • Install ductwork, if necessary, and accessories like thermostats or zoning controls

  • Charge the refrigerant and test the system

We will help you select the best type of system for your need and budget, with the features you desire, like zoning, variable-speed blowers or programmable thermostats. We work with all common AC equipment, including central air conditioners, ductless systems, heat pumps, packaged systems, and more.

AC Maintenance to Help Avoid Costly AC Repairs

Regardless of the age of your air conditioning system, it requires regular maintenance before the heating season and the cooling season to stay running efficiently and to prevent problems in the future. This includes steps like:

  • Replacing the air filter regularly

  • Cleaning the condenser coils and outdoor unit

  • Cleaning the air handler and evaporator coils

  • Inspecting the refrigerant lines for leaks and verifying the charge

  • Inspecting the electrical and safety systems

  • Cleaning the condensate drain

  • Testing the thermostat and control systems

Dial One can handle all your AC maintenance needs in Lancaster, from Danieldale Road to Bear Creek Road and beyond. When it comes to your home and comfort, don’t just trust anyone. Contact Dial One Plumbing, Heating, and Cooling for quality services you can’t find anywhere else.

Lancaster, TX 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 have the ability to install all types of furnaces, heat pumps, and other heating components.

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 in Lancaster

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.
