Electrical Services

Every Trademasters Electrician is licensed and insured to competently and safely perform electrical service, repair, and installation at your business. Our goal is 100% customer satisfaction, and a practical, experienced, no-nonsense approach to electrical repairs and service of all kinds, regardless of project size. Our technicians arrive on site when expected in a clean Fox uniform and vehicle, conduct themselves courteously and professionally, and leave with a tidy and complete job performed according to municipal code. No funny business or cut corners, just honest electrical work done right. Services we offer include but are not limited to:

Energy Efficient Retrofitting

Heating and cooling equipment over ten years old can be significantly less efficient than currently available systems. Upgrading an older system can not only help the environment, but also save money through reduced energy use, decreased down-time, and lower maintenance and repair expenses. Retrofitting an older, inefficient HVAC system can more than pay for itself in a very short time. Trademasters uses the latest state-of-the-art equipment and methods, applying a comprehensive approach to retrofitting that ensures your HVAC system's efficiency, reliability, and safety. Energy Star rated heating and cooling equipment can help you save up to 30% on energy costs and meet new environmental standards. It's a win-win for both the environment and your budget.

Client Care Agreements & Energy Audits

Our Client Care Agreement includes scheduled maintenance, which will keep your equipment running at peak efficiency, extend its life, and increase its reliability. Should you need emergency service, our CCA customers are given PRIORITY service and a 10% discount on repair services. Our experts can also conduct Performance Evaluations and Energy Audits and suggest ways to optimize climate control and resource usage for your particular needs.
