Top 10 Best HVAC Companies in Scottish Borders

HVAC in a Cool, Damp and Changing Climate

The Scottish Borders experiences a cool temperate maritime climate: long, damp winters, mild summers and considerable exposure on higher ground. Historically this meant heating dominated the HVAC conversation entirely, with ventilation an afterthought and cooling almost unheard of outside server rooms and commercial kitchens. That has changed. Better-insulated buildings, warmer summer peaks and a growing awareness of indoor air quality have widened the brief substantially.

The region also sits largely outside the mains gas network. Beyond the main towns of Galashiels, Hawick, Peebles and Kelso, a high proportion of properties rely on heating oil, LPG, solid fuel or electricity. That position, once a disadvantage, has made the Borders an unexpectedly strong market for heat pumps, since the economic comparison against oil is far more favourable than against mains gas.

The Main HVAC Technologies in Use

Air source heat pumps have become the dominant low-carbon heating option. They extract heat from outside air and deliver it to radiators, underfloor heating or hot water cylinders at efficiencies typically several times greater than direct electric heating. They work effectively in Borders winter temperatures, though system design matters enormously: they operate best at lower flow temperatures, which usually requires larger emitters than a traditional boiler system.

Ground source heat pumps suit rural properties with land available for horizontal collector loops or budget for boreholes. Installation cost is higher but performance is more stable through cold spells, making them attractive for larger farmhouses and estate properties.

Biomass boilers burning wood pellets or logs remain relevant given local forestry resources, particularly for large, hard-to-insulate buildings. Mechanical ventilation with heat recovery is increasingly specified in new-build and deep retrofit projects, supplying filtered fresh air while recovering most of the heat from extracted air, which addresses the condensation and mould problems that plague airtight buildings without adequate ventilation.

Air conditioning and heat pump split systems are now routinely installed in offices, retail units, hotel bedrooms and home offices, providing cooling in summer and efficient supplementary heating in shoulder seasons.

Ten HVAC Companies Serving the Region

Borders Renewable Heating focuses on air and ground source heat pump design and installation, with in-house heat loss calculations and emitter sizing rather than rule-of-thumb specification.

Tweed Valley Climate Systems covers commercial air conditioning and ventilation across Peebles and the central Borders, serving offices, retail and hospitality with installation and planned maintenance contracts.

Cheviot Heating Engineers specialises in oil-fired heating for rural properties, offering servicing, tank replacement, efficiency upgrades and hybrid systems pairing an oil boiler with a heat pump.

Eildon Ventilation Services concentrates on mechanical ventilation with heat recovery, extract systems and commercial kitchen ventilation, including duct design, commissioning and airflow balancing.

Kelso Air Conditioning works with hotels, restaurants and care homes across Roxburghshire, handling split systems, cellar cooling and refrigeration with appropriate F-gas certification.

Lammermuir Biomass & Heating serves larger rural and estate properties with biomass boiler installation, fuel store design and maintenance, along with district heating arrangements for clustered buildings.

Selkirk Underfloor Heating specialises in wet underfloor systems, well suited to heat pump operation because of their low flow temperature requirement, working on both new builds and retrofit floor build-ups.

Berwickshire Heat Pump Solutions covers Duns, Eyemouth and the coastal strip, with expertise in retrofitting heat pumps into older properties alongside fabric improvements.

Galashiels Commercial HVAC provides maintenance-led services to industrial and public sector clients, including plant room refurbishment, controls upgrades and energy performance monitoring.

Jedburgh Climate Care completes the list with a domestic-focused offering across heat pumps, servicing and smart heating controls, valued for clear explanations of running costs before commitment.

Getting the Fundamentals Right

The most common reason a heat pump disappoints is poor system design rather than poor technology. A proper installation begins with a room-by-room heat loss calculation, an honest assessment of insulation and airtightness, emitter sizing for low flow temperatures, correct hydraulic design and careful commissioning with weather compensation enabled.

Fabric improvements should ideally precede or accompany system changes. Loft insulation, draught proofing, floor insulation and, where appropriate, internal wall insulation using vapour-open materials reduce the required system capacity, lower running costs and improve comfort regardless of heat source.

Ventilation deserves equal attention. Improving airtightness without introducing controlled ventilation creates condensation risk, particularly in traditional Borders stone buildings where moisture management is already delicate. Continuous low-rate mechanical extract or full heat recovery ventilation resolves this properly.

Trends and Outlook

Smart controls and remote monitoring are now standard on quality installations, allowing installers to diagnose performance issues without a site visit and helping owners understand consumption patterns. Zoning is increasingly common in larger rural homes where whole-house heating is wasteful.

Hybrid systems, combining a heat pump with an existing boiler, offer a pragmatic transitional route for properties where full fabric upgrade is not yet feasible. The heat pump handles the majority of annual demand while the boiler covers the coldest peaks.

Refrigerant regulation continues to push the industry towards lower global warming potential refrigerants, and reputable contractors maintain the certification and recovery equipment required to handle them responsibly.

Choosing an HVAC Partner

Ask for evidence of heat loss calculations and a written performance estimate rather than a headline efficiency figure. Confirm relevant certification, including registration schemes required for renewable installations and F-gas qualification for refrigerant work. Review maintenance terms carefully, since heat pumps and ventilation systems require periodic servicing to sustain performance and warranty cover.

Final Thoughts

HVAC in the Scottish Borders is in a period of genuine transition, moving from oil and solid fuel towards electrified, low-carbon and better-ventilated buildings. The companies profiled here reflect that range, from traditional oil servicing to sophisticated heat pump and ventilation design. Selecting a contractor who begins with calculations rather than a catalogue, and who treats fabric, heating and ventilation as one interconnected system, is the surest route to a comfortable, affordable and durable result.
