Your Heating & Cooling Partner

Q: How much does AC maintenance cost?

The cost depends on the type and size of the unit. Contact us for a free estimate. Regular annual maintenance is significantly more affordable than repairing damage caused by neglect.

Q: Which AC brands do you sell?

We distribute equipment from world-leading manufacturers: LG, Daikin, Mitsubishi, Vaillant and Midea. All units come with full manufacturer warranty.

Q: Do you install floor heating?

Yes, we design and install underfloor heating systems for new builds and renovations. Floor heating is the most efficient and comfortable way to heat a space.

Q: How often should AC be serviced?

We recommend servicing your air conditioning unit at least once a year, ideally before the start of the usage season (spring for cooling, autumn for heating). Regular maintenance extends equipment life and protects your health.

Q: Do you offer warranty on services?

Yes, all our installation services come with a warranty. Additionally, all equipment we sell comes with a manufacturer warranty. We also hold an ozone layer protection certificate.

Sales, installation and maintenance of air conditioning, heat pumps and ventilation systems for residential and industrial properties.

What Our Clients Say

"They installed a Daikin multi-split for our three-bedroom apartment. They checked insulation, windows, orientation - then recommended the exact capacity we needed. Electricity bill is 30% lower than with our old unit. They come for annual service every spring without us having to remind them."

Nikola V.

Trebinje

"I called them on a Saturday morning because our AC started leaking. They came within an hour, found a clogged drain line, cleaned and disinfected the entire unit. Fair pricing and they explain everything before they start working."

Jelena K.

Trebinje

"They installed a Vaillant heat pump and underfloor heating in our new house. Winters in Bileca are harsh, but now it's always 22 degrees inside. We financed it through the bank in 36 installments. Full recommendation for the El Frigo team."
