Factors For Consideration When Choosing A New HVAC System

In any modern building, one of the most important components is the heating, ventilation, and air-conditioning system.
HVAC Buying Guide

Many customers still find it tricky understanding what factors they should consider when choosing the right one.

It can be hard to find non-specialised information that is easy for non-experts to follow.  Perhaps this is the place you find yourself.  If so, our guide below should help make the process of finding an HVAC system easier.

What HVAC system is right for me?

To begin with, you should give consideration to the dimensions of the area you want to heat and cool.  As well as making the unit you choose more convenient, buying one that is the right size, will help it to run more effectively.

Having a system that is too big will cycle on and off more often and be less efficient.  It will also cause much more wear and tear on the internal components and may stop it from ever working properly.  Although it may seem like a bad idea to invest in a smaller system, it may actually produce better results over time.

As the calculations involved in working out whether a system is too big or too small are rather complex, you should consider hiring an engineer.  ADK only employ the most experienced and knowledgeable HVAC engineers in the Wembley and Greater London area and would only be too happy to help you.

How do I get good value for my money?

Another important factor you should consider is whether or not a system will give you good value for money.  As is the case when buying any appliance, it is not a good idea to simply pick the on-budget or most affordable option.  This can actually be counter-productive, as cheaper systems can damage easier because of their inferior build quality, but may prove to be a hazard if quality control has not been followed correctly.

So when we speak of value for money, we mean an air conditioner that actually gives you good value for money, or in other words, pays off on the investment you made.

Although upfront, a more expensive, but better designed, more robust and better built unit will offer better value in the long run.  Not only will it last longer, but it will also require fewer repairs, saving you money.

What HVAC repair options are available to me?

The final factor we want to discuss is the repair options available. This is important because you will want to make sure that there are certified repair engineers in your area that deal with the specific brand or model you are interested in buying.

The good news in this regard is that if you give ADK a call, they will be able to tell you the brands and models of HVAC systems they deal handle repairs and installations options before you buy.

Although there are many other factors that you should take into consideration before and when buying an HVAC system for either a business or residential setting; these tips should help you to fine-tune your search considerably.

What HVAC add-ons do I need?

You can upgrade your existing AC unit with additional equipment. Before purchasing the unit, complete your research and get the add-ons. This practice ensures that the professional service can install all components with ease.

For instance, you can install a heat pump with your AC system. This will enable you to use your AC as both cooling and heating unit.

HVAC Maintenance Contracts

Our PPM (Planned Preventative Maintenance) plans are specially designed to ensure that your domestic and commercial air conditioning systems are working at their best capacity all year round. Saving you money in energy efficiency and minimising on-site disruption in the process. 

Customers with large business air conditioning systems and premises will need two major and two minor PPM visits a year. While most smaller business customers will need just one major air conditioning maintenance visit a year.

HVAC Repair Service

Our domestic and commercial HVAC service engineers can get out to you in under 4 hours if you’re located in London. So even if the problem’s urgent it won’t be long before you’re back up and running again. 

We have all the right HVAC equipment to make the necessary repairs. So you won’t have to wait around while we order in extra parts — unlike with some other companies. And we carefully tailor our HVAC air conditioning service work so that it causes as little disruption as possible.
