Why Copiague Customers Choose Tedco Mechanical

Being family-owned means our name is on every job we do. We don’t cut corners because we’re accountable to our customers and to our community. Our MBE certification reflects that commitment to integrity, and our core values, quality, dependability, and honesty, shape how we handle every service call.

1-Year Labor Warranty: Our work is covered by a 1-year labor warranty.
Manufacturer Warranties: Equipment we install carries the manufacturer’s warranty, giving you coverage on the equipment, while our labor warranty applies to our work.
Fast Response Times: We don’t leave you waiting. Same-day service is available when scheduling allows.

Heating Repair & Installation for Copiague Homes

Long Island winters don’t leave much room for a failing heating system. We provide heating repair, installation and replacement, and preventive maintenance for furnaces, boilers, heat pumps, and more, covering all major makes and models. If your system isn’t producing heat, is short-cycling, or is making sounds it didn’t use to make, those are signals worth acting on before a partial problem becomes a full breakdown.

Systems 15 or more years old often cost more in repairs than a replacement would over the same period. When you call us, we can give you an honest assessment of your options, not just the most expensive one. Same-day service is available for heating emergencies in Copiague, NY.

Air Conditioning & Ductless Mini-Split Services

Long Island summers combine heat and humidity in a way that makes a functioning AC system more than a comfort item. We handle AC repair, installation and replacement, and maintenance for cooling systems of all makes and models. If your system is blowing warm air, running constantly without cooling the space, or has stopped turning on entirely, we can diagnose it and work to get it running properly.

Ductless mini-splits are a strong fit for Copiague homes where adding ductwork isn’t practical, whether that’s an older house with a different layout or a room addition outside the original system. We install and service mini-splits and can help you determine whether one is the right solution for your space.

Financing, Warranties & Free Estimates

HVAC replacement is a significant investment, and a tight budget shouldn’t force you to delay work your home or business needs. WellsFargo financing is available for qualifying customers, making larger installations more manageable. Free estimates let you understand what a project will cost before committing to anything, and our 1-year labor warranty covers our workmanship separately from the manufacturer’s warranty that applies to any equipment we install.

- Joseph M.
"Quick & Courteous Service"
Frank responded quickly and courteously. He solved my problem in an hour after investigating my 18-year-old cooling system: clogged filter and no freon. I'm sure other companies would have told me the unit needed to be replaced. Now my AC runs ice cold.

Frank responded immediately and accommodated my schedule. He came out the same day and fixed my central air unit. He was upfront about the cost and answered all of my questions. Very satisfied.

- Brian D.
