Why Replace Instead of Repair?

An ageing AC unit that frequently breaks down or underperforms often costs more in the long run. Repairs may offer short-term fixes, but older systems typically lack efficiency, use outdated refrigerants, and drive up energy bills — especially during peak summer demand.

At RightAir Solutions, we help clients across West and North West London assess when a repair is worthwhile and when it’s time to invest in a long-term upgrade. From Victorian conversions in Hampstead to retail units in Notting Hill, we replace ageing systems with efficient, modern alternatives that offer reliable performance and better energy control.

The Case for Replacement: Long-Term Value, Lower Stress

Every air conditioning installers West London job we take on starts with an honest assessment. Here’s when replacement is often the better route:

  • Your system uses obsolete refrigerants like R-22

  • Repairs have become frequent and costly

  • Cooling is uneven or airflow is weak, even after servicing

  • Your energy bills keep rising despite regular maintenance

  • The system is loud, bulky, or visually intrusive

  • You want to integrate smart control or zone-based settings

  • Parts are becoming difficult or expensive to source

We don’t replace unless we know it’s the right move. Our goal is to give you quiet, efficient climate control that works beautifully in the background — and lasts for years.

We replace tired systems with smart, efficient solutions that reduce callouts, lower bills, and keep your home or business comfortable.

FAQs About Old AC Unit Replacements

If you have a question of your own, then please ask.

If your AC unit is over 10 years old, uses outdated refrigerant (like R-22), or requires frequent repairs, it’s often more cost-effective to replace it. We assess each system on-site and give you honest advice based on condition, performance, and long-term value.

In some cases, yes — if your pipework and wiring are in good condition, we may be able to replace the indoor or outdoor unit only. Our engineers will inspect your existing setup and advise whether a partial or full replacement is the most practical option.

Not usually. In most residential properties, replacing an existing unit with a like-for-like model does not require planning permission. However, we’ll always check site-specific restrictions — particularly in listed buildings or conservation areas — before starting work.

Most residential replacements are completed within 1–2 working days. For larger or more complex systems, we’ll provide a detailed timeline. We always aim to minimise disruption to your routine or business operations.

Yes. Modern air conditioning systems are significantly quieter thanks to improved compressor design, inverter technology, and noise-reduction housing. This is especially beneficial in bedrooms, living areas, and open-plan offices.

Absolutely. We’ll assess your space and discuss location options based on airflow, noise, aesthetics, and accessibility. We can often improve on the placement of your old unit to make the new system more discreet or efficient.

Yes. All new installations come with a full manufacturer warranty, typically ranging from 3 to 5 years. Our workmanship is also guaranteed, and we offer optional maintenance plans to protect your investment long-term.

We work with clients to find solutions that suit their budget. While we don’t offer in-house finance, we can stage projects in phases or prioritise upgrades based on urgency. We’ll always be transparent about costs from the start.

We install a wide range of premium brands, including Daikin, Mitsubishi Electric, Panasonic, Fujitsu, and others. We’ll recommend the best system for your space, whether that’s a sleek split unit or a powerful VRV system.

Yes. We handle full removal of your old unit, including safe refrigerant recovery and compliant disposal. Everything is managed according to UK environmental standards — so you won’t be left with anything to worry about.

Each visit includes a full health check, component testing, and on-the-spot repairs where possible, with no obligation for follow-up services.

HVAC Servicing

Seasonal Performance Optimisation

London’s extreme seasonal temperatures can push AC systems to their limits. Our pre-season servicing is designed to get your compressor and associated components ready for high-demand periods — whether that’s a heatwave or a winter chill. Ideal for offices, restaurants, and retail premises, it helps prevent costly breakdowns during your busiest months.

Seasonal HVAC checks

Filter Cleaning and Airflow Efficiency

Clogged or dusty filters restrict airflow, causing your AC unit to work harder than necessary — which can overheat the compressor and increase running costs. Our engineers carry out full filter cleans and replacements as part of routine servicing, helping to extend system life, cut energy use, and keep indoor air cleaner and healthier.
