Furnace Installation, Maintenance, and Repair Services

We can handle custom designs and retrofitting with our full sheet metal shop, too!

Automatic Refill Service

Are you worried about running out of heating oil? Worry no more! Glendale’s Automatic Refill Service is carefully designed to keep your tank level throughout the year. Utilizing information supplied by the national weather bureau, our system forecasts when you are due for an oil delivery, ensuring a comfortable margin of oil in your tank at all times. Our system monitors your consumption habits during both hot and cold weather, so we always have you filled up and ready to heat.

Air Conditioning Installation and Repair

Air conditioning keeps you cool when summer temperatures soar. Glendale specializes in residential air conditioning equipment replacements. We proudly install Lennox air conditioning systems. Lennox is the largest manufacturer of air management equipment in the U.S.A. They are a leader in technological innovation, with research and development facilities dedicated to constantly improving equipment. Glendale is proud to have been an independent Lennox dealer since 1966.

Oil Tank Replacements Agreements

Replacing an oil tank is a big investment. As a service to our Automatic Refill customers, we offer Oil Tank Replacement Agreements for a small yearly fee. If your tank needs to be replaced, we will have it done at no charge to you. We also participate in the Washington State Pollution Liability Insurance Program, which covers active heating oil tanks for up to $60,000 in third-party remediation cleanup if any oil leakage does occur. The annual fee is a small price to pay for some serious peace of mind.

Annual Service Contracts

An Annual Service Contract can save you time and money. More than just a convenient way to pay your bill, Glendale’s service contracts are true home heating management for your Seattle heating and cooling systems. Our contracts include a yearly safety and maintenance check, coverage for all labor costs for service needed during the year, and the assurance of priority service.
