Homeowners can customize their Tempstar high-efficiency oil furnaces by selecting the burners for the unit during installation. These high-efficiency models also feature a variable speed EMC motor to reduce noise and allow for higher quality air flow throughout the home. Easy maintenance, pre-wiring for add-ons, and an accessible control panel are added benefits of these units.

Tempstar Performance Series Oil Furnace

Consumers looking for easy installation, maintenance, and use might consider Tempstar’s Performance Series. This line features a large external front for simple care and maintenance, an easily accessible control panel, and factory installed sight glass for quick set-up and service. Additional features of the Performance Series include a patented ceramic combustion chamber and multiple direct drive motor blowers for quiet and efficient operation.

Care and Maintenance

While homeowners can perform basic cleaning and maintenance, Tempstar requires annual maintenance by a qualified service technician to keep the unit’s warranty valid. Consumers can find an independent heating and cooling contractor in their area by visiting Tempstar’s website and using the “finder a dealer” function.

Warranty Information

Consumers are eligible for a 10 year, limited parts warranty if the furnace is registered within 90 days of installation. If the unit goes unregistered within the allotted time period, the warranty term will automatically decrease to 5 years. Tempstar furnaces are also equipped with a 20-year or unlimited warranty on heat exchangers depending on the product purchased.

Extended coverage of major components is available through the No Hassle Replacement plan. Coverage length varies upon purchase.

To aggravated right now to type and wishing I spent the little extra to buy quality. My bad! I know you read these and say, meh how poor can they be, lets do it….DON'T You will regret it.

"What I know"

3.0 rating

I moved in to this home 15 years ago. First year during very cold temps, limit switch went. Guy came out on an emergency call while I was at hospital with my mother and installed a different high limit switch then what Tempstar called for, and it went again, but luckily it lasted about a month or so until it did. This older model required a specified limit switch part and we found it and made sure it was put in and furnace was fine for sometime. Had to replace normal parts since then. Blower motor still works well, inducer draft motor went (original part) went at about 19 years after the make of the model manufacture date. That is not bad. Replaced an Hot surface ignitor after living here for about 10 years. [Probably not original, but still a good length of time because those parts go sooner}. Hsi module board replacement once at about 12 years of living here. All these parts are not that expensive and expected. Now after a 26 year old furnace I am looking for a new one. I expect to get a quote from tempstar again, along with brands. Some items you just expect to replace because of age and use. The thing I worry about now are heat exchangers on my old furnace, so time to bite the bullet. My tempstar ac has been working fine for all these years, so not bad either, it was installed at same time. I would just do a check on any of already installed newer models of furnaces to see if there has been any recall or troubles on specific parts. One major thing I see with these variable fan motors on newer furnaces on any kind seem to be the fan motor burning out quickly. My blower fan motor is the original on the tempstar, and the capacitor still holds the correct amount. This tempstar is a one stage blower 1/2 hp. With no oil ports [self oiling]. This furnace has lasted pretty well at 26 years.

"Awesome product"

5.0 rating
Very Satisfied

I'd like to say that I am very satisfied with this Tempstar brand 99.9% of the issues that we end consumers have with our systems is due to poor installation by individuals that are not properly qualified to do the job. Anyone with common sense will know that that goes the same for any other product out there. This Tempstar unit that I have installed in my home tsa 6 – 16 seer is a super quiet and yet out performed my old Goodman I recommend this manufacturers brand which of whom is essentially a Carrier product doing my research ICP cooperation makes Carrier, Bryant, Tempstar, day night, Payne and their product is also under a number of names as well. They are all the same equipment different models different metal exterior designs however the equipment compressors and system components are exactly the same with all the different brands at which they make again this is doing my research once again I am 100% satisfied with my Tempstar I believe those of us that have the bad experience and leave really bad reviews are due to very poor installation of the equipment by unqualified individuals.. Hope this is helpful to any and everyone out there!!



"Contractors opinion"

3.0 rating

As a service person for 33 plus years I can read between the lines of complaints on any brand furnace. What I'm seeing is the customers that feel they have a junk furnace, need to know any furnace is only as good as the installer or service tech working on it! It's sad equipment takes a bad rap for poor workmanship, or a tech that doesn't know how to use a meter!

"Stay Away."

Very Unsatisfied

Stay Away. Did not work properly from day of installation. Replaced Mother Board twice. Replaced pressure relief valve day of installation. Replaced thermostat 4 times. At least 2 service calls a year. After 10 years of never knowing if it was going to kick on and crazy blink error codes I bit the bullet and replaced this lemon. Never buy a tempstar heater. My advice
