Buying a Home – Free pre-closing heating system inspection
Our expert heating service technician provides a full inspection and test of the heating system before you close on your home. If the heating system is in good working order, we’ll guarantee it with Marran’s All Risk Service policy, which covers the entire system. Marran’s pre-closing inspection gives homebuyers one less thing to worry about.

Selling Your Home
Marran can provide your attorney with a closing letter, which allows for reimbursement of the remaining oil in your tank and the value of the remaining equity of your service policy. Please contact us at least three days before your scheduled closing date.

Smart Landlord
A smart landlord protects his home by requiring tenants to purchase oil and service directly from Marran. By doing business directly with Marran, tenants will never have to call the landlord for an emergency heating service.

Landlords choose Marran because we:

• Provide landlords with credit checks on a prospective tenant

• Open a Marran account directly with the tenant

• Provide 24 hour emergency service

• Perform annual maintenance on the heating system that otherwise a tenant might never have done.

• If the tenant’s account with Marran falls into arrears, we keep the landlord informed.

If you want to use Marran, you should include the following stipulation in the lease or rental agreement: “Tenant must purchase oil on automatic delivery and All Risk Service policy from Marran Oil LLC.”
