If you are planning to live in your home for an extended period of time, an ultra-high efficiency modulating system is strongly recommended. With an efficiency of up to 97.4 percent AFUE and a 10-year parts and lifetime heat exchanger warranty (when registered) among other benefits, this type of furnace offers the best return on your investment in energy and maintenance savings alone. Even if you plan on living in your home for less than five years, it’s possible that a modulating system can increase the value of your home when selling. Of course, there are several efficient options that can meet your comfort preferences and budget. We’re happy to provide a recommendation that fits you and your home.

Yes, it’s important to know that you’re not comparing apples to apples when looking at estimates for a tune and clean service. At Seider, we don’t have a cheat sheet in order to keep the cost low. Our 18-point furnace maintenance and safety inspection includes everything from adjusting and cleaning the pilot light, burners, and controls, to checking components and controls—and ultimately making recommendations for improving efficiency.

Because they are so comprehensive and performed by our experts, clean and checks are always a good value at Seider. Be sure to get on our mailing lists for special savings in the regular mail and by email.

The easiest way to remember changing your filters—and batteries in smoke alarms and carbon monoxide detectors—is to change them all at once, twice a year, during Daylight Savings. (At the very least, an annual change is recommended.)

We recommend annual tune-ups. Your equipment can be tuned up any time during the year and does not have to be done before the start of the heating or cooling season, as long as it’s tuned up once a year. To eliminate any surprise repairs and beat the seasonal rush, turn your furnace on before the weather changes to see if it’s properly heating.

Make no mistake, all providers charge a fee for in-home estimates—many just bury the cost into the estimate. We’re upfront and share that the fee is currently $89. After that, repairs are based on flat-rate time and materials. Our service tech will quote the cost of repair and thoroughly explain the service before getting your approval to do the work, but the $89 will always apply.

You can either complete our contact form or call. We will be happy to set up an appointment with you—all sales estimates are free.

We service all makes and models of furnaces and air conditioners.
