Why one company for both trades
Most new systems need electrical work too: a new circuit, a disconnect, sometimes a panel upgrade. Most HVAC companies hand that off to an electrician, which means a second schedule and a second bill. Callison holds a VA Class A license in both trades, so the estimate covers the whole job and one crew finishes it.
Financing. Financing is available on qualifying installs and larger repairs through approved lending partners, subject to credit approval. Ask about current options during your estimate.
From Google reviews
“Jimmy and Crew installed 2 heating and cooling units. One a mini split, the other central air and heat! Also, they found a way to run duct work to the original house where it looked like to me that installing it would not be an option.”
“They also lay out all the options with detailed estimates so you can see what works within your budget.”
“The best people for your hvac needs. We couldn’t be happier with the unit they installed in our house.”
