Hence, today’s article will feature the best HVAC service providers in Dublin to help you get whatever air conditioning, ventilation, and heating services you need.

We’re also giving you other info such as answers to some FAQs and tips to help you choose the right HVAC company. 

Ready to see our top picks? First, let’s take a look at some facts about HVAC service costs. 

HVAC Service Costs in Ireland

In terms of air conditioning units, the costs are dependent on a number of factors, such as efficiency rating and size, according to Trusted Services Ireland

Also, expect commercial applications to be pricier than those made for residential use.

Another factor that can affect the cost of air conditioning installation is the absence of existing ductwork and the capability of the building’s electrical system. 

As regards heat pump installation, air-source heat pumps cost between €8,500 to €14,500. Meanwhile, ground source systems range from €12,500 to €23,500, according to Electric Ireland

You’ll need to consider the age and size of your property, levels of insulation and thermal efficiency, the number of rooms and radiators, among others.

How to Choose a Good HVAC Service Provider 

How do you choose the right company to provide you with the HVAC services you need? Check out the tips below:

1. Know your needs

First, determine the type of HVAC services you require. This will help you narrow down your search to the HVAC companies that provide the particular services you’re looking for.

Do you need installation services? Repairs and maintenance? Or are you particularly after a company that provides 24-hour emergency services, especially if you’re a business owner?

If it’s HVAC rental solutions that you require, some HVAC companies specialise in this. 

Meanwhile, if you’re on a tight budget, then you may want to specifically look for companies that offer finance options to help you spread your payments. 

2. Take note of important details

This means knowing your system’s model and the past repairs conducted to it. 

Take note of particular problems you’re experiencing with your HVAC system, such as which rooms are warmer or needs more coolness, and so on.

3. Warranty

A good HVAC service provider will offer a warranty on parts and labour. This will help ensure you’re getting quality services and that they’ll be responsible if you spot any problems in the future after they do their work.

Check for insurance coverage as well. 

4. Credentials

HVAC services should be carried out by experts. Ask your prospective HVAC company for proof of their training, accreditations, memberships, and so on.

Examples of these are F-Gas certification, RECI certification, EPA certification, RGII registration, and so on. 

5. Portfolio

This part is especially useful to larger customers such as commercial and industrial clients. 

Some HVAC companies provide a portfolio of their past projects, detailing the work they’ve done in various sectors as well as the clients who’ve hired them. 

Hence, you’ll know about the extent of the company’s experience in the industry, particularly, in the sector where you belong.
