Quick answers

Do you offer commercial maintenance contracts in Spring Hill?


Yes. We set up preventive maintenance contracts for Hernando County businesses, with priority scheduling and discounted repairs. Each contract gets a written estimate, because the number of systems, visit frequency, access and coverage set the price.

What is a commercial energy audit?


It is a review of your current system and energy use to find where you can save money or improve comfort. We look at equipment sizing, controls and system design, then give you a written proposal with pricing options.

Can you come on a Friday night if our AC fails?


Yes. We provide after hours and weekend emergency service for Spring Hill businesses from our office at 2116 Mariner Blvd Suite B. The commercial diagnostic visit is $285 after hours and on weekends, or $185 during regular hours, and our commercial HVAC cost guide explains what repairs add.

Nicole B.

Goose and Kyle are life savers! They saved our business today and prevented us from having to purchase a new unit. Can’t say enough about this company! We’re getting ready to set up a maintenance plan with them to prevent any future disasters. Goose was extremely professional, quick, and thorough with our unit. He definitely put our business at ease and got us same day air conditioning. If anybody is looking to utilize an air conditioning company, Farrell is the way to go!!!

How long should my AC system last in Florida?

In Florida, most central air conditioning systems last between 10 and 15 years with proper maintenance. The heat and humidity put extra strain on equipment compared to cooler climates, which is why regular maintenance is especially important here.
