Llanelli’s Dependable and Expert Boiler and Central Heating Servicing

An annual boiler service is the best way to keep your boiler operating at peak efficiency and lower the possibility of any issues that could lead to a breakdown and the need for an emergency boiler repair. When you book an annual boiler service with us, one of our qualified Gas Safe engineers will visit your Llanelli residence or place of business and carry out a thorough and certified boiler service. The age and type of the boiler, as well as any potential system issues, will all affect how long the boiler service takes, but it is normally no longer than an hour, and we guarantee hassle-free boiler services in Llanelli. 

An annual boiler service helps identify and fix issues before they get worse and often become costly problems. Potential issues can be avoided before they happen, often leaving you without heat or hot water when you least expect it. Many boiler issues are identified and resolved during a boiler service, meaning no inconvenient and costly breakdowns. As well as this, maintaining and servicing your heating system will lengthen its lifespan and avoid the need for an early replacement.  

Your heating system’s effectiveness and safety are guaranteed when you invest in an annual boiler service. An efficient boiler reduces energy consumption, which lowers energy costs and improves the economy and sustainability of a house or business. A boiler that is properly maintained and serviced regularly uses less energy to heat your property to the same degree. For you as a homeowner or business, this increased efficiency lowers your heating bills by reducing energy waste.

Our Boiler Servicing

  1. A certified heating engineer from our team will examine your boiler to ensure that it is installed correctly and that the connecting pipework is placed appropriately
  2. To determine whether there are any problems with the appliance, our engineer will turn on your boiler and see it in working order 
  3. They will test the boiler’s working pressure to make sure the gas supply satisfies the minimal requirements set by the boiler manufacturer and look for any gas leak
  4. They will look for any worn components that might require replacement or present you with issues later on
  5. After the boiler service is finished, your engineer will walk you through the process and checks they have completed, clarify any problems that were found, and let you know if any repairs are needed
  6. If repair work is required, we promise to provide you with a fixed and competitive quote 
  7. We pledge to be open and honest with our clients, and we will never try to upsell you on anything you do not need. If necessary, you will get a thorough breakdown of the scope of the repairs that need to be done, as well as a reasonable fixed quote for the estimated cost of those repairs 

To ensure that your boiler functions effectively throughout the cold weather and winter months and to avoid costly repairs later on, you should schedule an annual boiler service for your Llanelli home or place of business. When providing you with an annual heating and boiler system service, our qualified and experienced engineers commit to being on time and working quickly and efficiently. By investing in our servicing expertise, you can avoid boiler problems at any time of the year.

Why Is Boiler Servicing A Necessity?

Having served customers in Llanelli for more than 40 years, the team at Eric Collier & Son has the know-how to provide the best advice to ensure that their central heating systems and boilers remain in optimal operating condition. We also handle all other necessary heating services for gas, oil, and LPG appliances.  

We advise having a fully qualified gas-safe heating engineer, such as Eric Collier & Son, service any type of boiler at least once a year. Frequent boiler servicing can assist in identifying any potential problems that may worsen over time and necessitate an expensive boiler repair. In addition to being inconvenient, a malfunctioning boiler can be extremely dangerous for your family members or workers. Harmful carbon monoxide can spread through a leak and endanger the health of everyone inside a building. A professional and knowledgeable boiler service will reduce the chances of this, as well as help you save money on your energy costs as it guarantees that your boiler is operating at peak efficiency, reducing your energy output and operating costs.

Landlords are legally required to have all gas appliances at any property they rent out annually serviced by a fully qualified, registered gas-safe engineer.

Air Conditioning & Refrigeration

At Eric Collier & Son, we understand that selecting the best air conditioning system can be challenging given the abundance of options.

Maintenance and servicing are essential if you want to get the most out of your air conditioner and prolong its lifespan. By doing this, you will be able to save money and have a cosy interior setting. Our team installs, services, maintains, and repairs all makes and models of air-con units. 

Any industrial air conditioning unit needs to run as efficiently as possible, but this cannot be done without regularly scheduled servicing. The accumulation of dirt and grime in air conditioning units due to frequent use of the cold temperatures they generate not only reduces the quality of indoor air but also makes the unit work harder than it needs to. This extra strain on an already overworked AC unit leads to increased energy consumption, which, if neglected for a long time, can eventually cause damage.

Contact us today to arrange a no-obligation servicing, repair, or installation survey appointment.
