It caused intermittent problems, and I finally had to go spend $100 at a full auto mechanic shop to get it fixed. Clearly jiffy lube's guy didn't look the part up in the book, just thought he knew and put the wrong one in.

One burner is slow to heat so tech will order another part and set up an appointment to replace it
The hot water heater stopped working on 8/2/2014. I took them some time to come but they had to replace both heating elements. It was covered by the warranty. The plumber had to give me a lecture about me causing the heating element failure because I turned the temperature up on the...

Heating Oil questions, answered by experts
There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.
You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).
Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.
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.
Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.
Costs depend on system age, type, labor, and whether part replacements are necessary.
For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
