Whether it’s heating and air conditioning service or plumbing repair you require, Horizon technicians are happy to help.

Air Conditioning

AC is vital for your summer comfort. To keep you cool when temperatures soar, we provide professional tune-up services for your air conditioning. We also install Nest Smart Home thermostats, replace outdated AC units, and deliver emergency services as necessary.


Families rely on heating to keep them safe and warm all winter. But when was the last time your heater had a tune-up? Our technicians are experts in furnaces, heat pumps, and boilers. Whatever system you have, our experts can repair, replace, or install accordingly.


Replacing a faucet or addressing a clog isn’t always a DIY job. In some cases, expert help is crucial. Our technicians also cover drain cleaning, installation of new plumbing systems, and sewer pump installs. Routine maintenance is another specialty—keeping you from experiencing sewer woes in the first place.
