Heater Installation in Delaware

If your home heating system has failed and is 12 years or older, then replacing it may be an obvious choice. But there are reasons that you may want to replace a unit that is still running. Perhaps your gas or electric bill is higher this winter than ever before or you want to convert from oil to heat, for instance. In either case, Oliver sells and performs precision high-efficiency furnace, heat pump, and boiler installations in Delaware. Call us at (888) 810-2681 or contact us online to speak with one of our comfort specialists. We can explore your options, answer your questions, and help you get the most out of your budget.

Heater Maintenance Gives You Peace of Mind

To help you cut down on monthly heating expenses, extend the life of your equipment, and avoid costly repairs, Oliver recommends routine heating services. Our HVAC maintenance plan makes this easy and affordable, providing regular inspections and cleanings. Membership also includes priority service, no overtime fees, and discounts on any repairs needed.

Types of Heaters We Install

Our reputable heating company in Delaware caters to all heating systems used in the region. We specialize in installing high-efficiency furnaces, heat pumps, and boilers and handle maintenance and repairs for any system type, including electric, natural gas, propane, and oil. We also offer system conversions to meet your needs.

Furnaces

In Delaware, furnaces are the top choice for home heating. Though electric furnaces are available, many homeowners prefer natural gas, propane, or oil models. These forced-air systems use ductwork to circulate heat and need their components inspected and cleaned regularly before the start of each season.

Heat Pumps

Among the most efficient heating solutions for homes, heat pumps also offer cooling capabilities during the summer months. They use electricity to transfer energy rather than producing heat directly. When paired with a furnace, they provide supplemental heat and, similar to furnaces, require regular seasonal servicing.

Boilers

Hydronic heating systems, such as boilers, use hot water or steam distributed through pipes to radiators. They are not only efficient but also deliver steady warmth that many people appreciate. As with all heating systems, boilers require seasonal maintenance to keep them running smoothly.

Elizabeth L.

Excellent experience with Oliver. I was looking for an established business that offered both whole house duct cleaning and a maintenance contract for both my heater and A/C unit. The phone representative was professional and left me feeling confident about my choice in business at the end of our discussion. There were two technicians for the whole house cleaning that were professional, knowledgeable and were able to clearly explain each step of the process. They protected my hardwood floors while getting their equipment to the heater in the basement and left everything in better condition than when they arrived. Oliver managed to get a third technician scheduled to come out the same day after the duct cleaning was completed to do the scheduled maintenance on my heater. The third technician was also professional and was able to very clearly explain what was involved with the maintenance on the heater and its current status. The costs were reasonable and the personal interactions across all levels was great. I highly recommend using Oliver's services.

Mike D.

Joe McLaughlin brings his knowledge, skills and work ethic into your home. Nice guy too.
