"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt.
