Question 1

How quickly can you replace a commercial rooftop unit?

Accepted Answer

Most rooftop replacements are completed within days once equipment is approved and scheduled — not months. When a unit fails outright, we can often quote the same day and set the new unit within the same week, depending on equipment availability and crane scheduling.

Question 2

Do you handle permits, crane coordination, and equipment disposal?

Accepted Answer

Yes. Permits, crane and rigging coordination, street or lot staging, removal of the old unit, and disposal are all included and managed in-house. You sign one contract with Shepherd HVAC and we coordinate every trade and vendor involved.

Question 3

Can you work around tenant schedules or business hours?

Accepted Answer

We regularly install nights, early mornings, and weekends so tenants, kitchens, and production lines stay running. Tell us your operating hours during the evaluation and we'll build the schedule around them.

Question 4

How do I know if I should repair or replace my rooftop unit?

Accepted Answer

Age, refrigerant type, compressor condition, and repair history usually decide it. If a unit is under roughly ten years old with a repairable failure, repair is often the smarter money. Once repairs approach a large share of replacement cost — or the unit still runs R-22 — replacement pays back faster. We'll give you both numbers so the choice is yours.

Question 5

Are your technicians licensed and certified?

Accepted Answer

Yes. Shepherd HVAC is fully licensed and insured (License PA194586), and our commercial crews are EPA and OSHA certified. Rooftop work is performed by dedicated commercial technicians, not residential crews scaled up for the day.

Question 6

What brands do you work with?

Accepted Answer

We install and service all major commercial brands, including Daikin, Trane, York, Mitsubishi Electric, LG, Carrier, and Lennox. We'll recommend equipment based on your building's load, curb, and budget — not on what one manufacturer pays us to push.

Question 7

Will a new rooftop unit reduce operating costs?

Accepted Answer

Almost always. Modern packaged units use far less energy than 15- to 20-year-old equipment, and newer controls and economizers cut runtime further. Most owners see a meaningful drop in monthly energy spend plus the end of recurring repair invoices.

Question 8

What warranty comes with a new rooftop system?

Accepted Answer

New units carry factory-backed parts warranties, typically five to ten years depending on manufacturer and registration, with extended compressor coverage available. Our installation workmanship is warrantied separately, and we register every unit for you.

Question 9

Do you offer pricing for multi-building portfolios?

Accepted Answer

Yes. Portfolio owners get consistent flat pricing across sites, one point of contact, and documented equipment and service history per building. The more units we manage, the better the pricing gets.

Question 10

What happens after installation?

Accepted Answer

We commission the unit, verify airflow, refrigerant charge, and controls, and walk you through the startup report. You get warranty registration, as-built documentation, and the option to add the unit to a preventive maintenance agreement.

Question 11

How disruptive is a rooftop replacement?

Accepted Answer

Less than most owners expect. The crane pick itself usually takes a few hours, and we stage the work so parking, entrances, and tenant spaces stay usable. In many buildings, occupants only notice the temporary loss of conditioned air during the changeout.

Question 12

Do you offer emergency rooftop replacement if a unit fails?

Accepted Answer

Yes. If a unit is down, call us and we'll get eyes on the roof fast, provide a same-day quote where possible, and discuss temporary cooling or heating options while the replacement is scheduled. We're available 24/7, even on holidays.

Question 13

What does a commercial rooftop replacement cost?

Accepted Answer

Cost depends on tonnage, curb condition, electrical, crane access, and controls. We quote one flat price covering equipment, rigging, permits, installation, and disposal — so the number on the proposal is the number on the invoice.
