Shipping Information

Delivery Times and Shipping:

Delivery times may vary depending on your zone. All orders are processed upon receipt. Actual shipping time is contingent upon availability of merchandise and credit verification. Unfortunately we do not guarantee any delivery times. This is because we are dependent on outside delivery agents such as UPS who do not guarantee their delivery schedules. Please do not schedule contractors until your products have arrived. HVAC Maintenance will never be responsible for any time guarantees in shipping, and we cannot and will not be responsible for any inconvenience or any loss, penalty, or extra charge incurred by our customers should any delivery take longer than anticipated. Packages that have tracking numbers but have not been received will be the customers responsibility to contact the shipping company and follow there instructions before claims are filed and a reshipment is placed. That being said, we strive to provide accurate lead times and timely updates should any lead time estimate change. We value our customers, appreciate their business, and will do everything in our power to serve you well.

We mainly will ship UPS , but sometimes orders that are shipped from the manufactures will be shipped at there own discretion. P.O. box addresses will not be shipped to at the current time, except when customer deems it ok. At any rate the customer will be responsible for any and all extra charges if PO Box is not accepted or wrong address is given. Most orders are shipped within 2-5 business days of receiving your order, with the exception of special order and non stock products. No orders are shipped on Saturdays or Sundays. In the event of delays, every effort will be made to contact you by phone, e-mail or mail.
