Compare the property service plans before requesting an equipment survey. Final scope and pricing depend on the systems and property involved.
How service works
What happens after you request service.

Assess the equipment
A technician assesses the system and the concern before recommending work.
- 4
Review the scope and estimate
We explain the proposed work and estimate, and ask for your approval before proceeding.
FAQ
Light-commercial questions
Is my commercial property a fit for your services?
We support qualifying light-commercial properties. Include the property type, ZIP code, number of systems, and equipment information so we can confirm the fit and service coverage. Coverage is in Washington, DC and nearby Maryland within about 20 miles, not throughout Maryland.
What should a property manager include in a request?
Identify the affected system or area, the reported symptoms, occupied hours, access arrangements, and the contact who can discuss the work. If several systems are affected, explain which areas they serve and whether the issues began together.
Are there maintenance options for multiple systems?
Yes. The property service plans let you compare Standard Preventive Maintenance with PM + Minor Component Coverage. Scope, eligibility, and final pricing are confirmed after an equipment survey; requesting information does not enroll the property.
Can I include building access and scheduling restrictions?
Yes. Tell us about occupied hours, access limitations, and preferred timing when you request service. Coverage and scheduling are confirmed directly. A submitted request is not a confirmed appointment or a promise of a particular service time.
