    Common Questions

    Frequently Asked Questions about Air Conditioning Installation

    We understand that you may have questions about air conditioning installation and how it can benefit you. Here are some of the most common questions we receive, along with detailed answers to help you make an informed decision.

    How much does it cost to install an air conditioning unit?

    The cost of installing an air conditioning unit can vary depending on factors such as the type of unit, the size of the property, and the complexity of the installation. On average, installation costs can range from £1,000 to £3,000. Contact us for a detailed and customised quote based on your specific needs.

    How do you install an air conditioning unit?

    Installing an air conditioning unit involves several steps:

    • Assessment: Evaluating the property to determine the best location for the unit.
    • Mounting: Installing the indoor and outdoor units securely.
    • Wiring: Connecting the units to the electrical supply.
    • Piping: Installing refrigerant lines and drainage pipes.
    • Testing: Ensuring the system is operational and efficient. For safety and optimal performance, it’s best to hire professional installers.

    How does air conditioning work?

    Air conditioning systems work by removing heat from the indoor air and transferring it outside. The process involves the use of refrigerants, which absorb heat as they evaporate and release it as they condense. This cycle continues, providing a consistent cooling effect and maintaining a comfortable indoor temperature.

    What size air conditioning unit do I need?

    The size of the air conditioning unit you need depends on several factors, including the size of the space you want to cool, the insulation of the property, and the local climate. Our experts can perform a detailed assessment to recommend the appropriately sized unit that will efficiently cool your space without wasting energy.

      When requesting a quote, I received a speedy reply from these guys and an initial visit was arranged shortly afterwards, then upon agreeing on the details and the price, they could offer a brilliant timeline for completion. The job was conducted much more quickly than promised and I am very happy with the result. The electricians working in my home were very nice and friendly and they made sure that everything they did was to my satisfaction.

      Based on other positive reviews I contacted Klisi to do some urgent and much needed repairs. He made his inspection and provided the quote that same evening. He and his colleague worked well as a team. They were friendly efficient and did the job professionally and with care and kept us informed when necessary. They left the premises clean and tidy. They are an excellent choice and offer a high quality seŕvice. I was so impressed that I look forward to welcoming them back to undertake some additional work. Thank you both!

      I cannot praise Klisi enough for the splendid electrical work he and his brother completed at our house. They were very competent and kept me well informed throughout the work. I was also super impressed with how tidy and clean they worked. I wouldn't hesitate to have them back to look at any other electrical jobs in our house in future. Thank you.

      Klisi responded promptly over the phone and came to do a little survey at first. He gave an immediate quote and after few days he came to do the job. He had to come a second time, didn’t charge nothing for second visit and completed the job to an high standard with professionalism and courtesy.

      We did quite a lot of work with Klisi and his team as we moved to a new home, and they were amazing. They checked our electric board and repaired it, added news plug sockets in our Victorian house, and a few more things. The team was very professional, quick, accommodating and lovely. Definitely calling them back next time we need anything done.

      This is the first time I have used Contact Electrician Ltd. Klisi was prompt in replying & very responsive in communications. He was able to get an electrician out to me in 48 hours & that Electrician (Eli) was polite, professional, & very capable. I am very pleased with the work.

      Had a couple of jobs done and I’m extremely happy. The guy went out of his way to find the parts, kept me updated all the way, arrived on time, was polite and very efficient. He even sourced the bulbs for the light fixture, one of the jobs he was doing. A very fair price. One very happy customer. Shall not hesitate to recommend and use again.

      Klisi is a very supportive electrician who takes the weight off your shoulders when dealing with tenants and gets the job done. Never met the guy but only communicated by WhatsApp and both jobs done without a fuss. He is my go to man as trust and reliability is the most important thing in a tradesperson. Can’t wait to have him do work in my home as well and will be recommending him to friends and family. Thank you Klisi.
      ★★★★★

      Helpful, friendly and professional service. Klisi responded quickly to my messages and was flexible with times owing to my switch & pendant light arriving on separate days. Samuel did a great job with care & consideration of the property. Would highly recommend. Thank you guys.

      Kristian Webb
      Great - experience. I had an unknown electrical fault repeatedly tripping my fuse box. Dani arrived at 8 o clock on the dot, unfortunately the problem wasn’t straight forward so another electrician Johnny attended too. They eventually found the issue and got everything working. The guys were really good - price was extremely fair. Will 100% use them as my electricians from now on. Highly recommended.
      ★★★★
      Lucy Jacobs
      Expensive because he was there for a while but the guy was lovely, tried really hard to fix a tricky problem, felt like he knew what he was doing, turned up at short notice and stayed till he found a resolution. Thank you 🙏

      Emily
      We could not recommend Contact Electricians more highly. Jonny and Denni (forgive me if I've misremembered their names!) worked so hard to do remedial work following an EICR at our property - they replaced our fuse box and were able to come out quickly following booking. They were kind, explained all the changes they'd made and then cleared up the site they were working on so neatly. We will be using this company again!

      Had a very positive experience with Contact Electrican Ltd - Klisi did a great job replacing an old consumer unit with a new metal version and created minimum disruption while I was working from home and left everything tidy after doing the work. A team also came to install a network of smoke and heat alarms in our apartment block and did this efficiently and for a competitive price. Would highly recommend.

      Really happy with the service. I had an issue with my Megaflo and was left without hot water. They came out quickly, properly investigated the electrical issue and explained clearly what needed to be done. The repair was completed promptly and for a reasonable price. Very professional and helpful — I would definitely recommend.

      I cannot recommend Klisi and Contact Electrician enough. After having truly disastrous experience with a precious electrician, he stepped in and turned the situation around completely. He responded to my inquiry remarkably fast and handled the job with the utmost professionalism. A clear thorough detailed EICR report was quickly provided. Absolute lifesavers-fair and honest
