Furnace and AC Maintenance Why Your HVAC System Is Like Your Car The average driver puts about 15,000 miles on his or her car each year, which equates to 540 hours. After all of that hard work, you wouldn’t neglect annual maintenance on your vehicle, would you? So why not show your furnace – a vital part of your home – the same kind of love? Understandably, you use your car practically every day, so routine oil changes are easy to remember and issues are easy to detect. Your HVAC system is tougher to keep top-of-mind as it is locked away in your basement or in a closet, somewhere behind closed doors. If you have a heat pump and compare it to your car running at 55 miles per hour, it runs about 170,000 miles per year (that means about 1.7 million miles in ten years and 2.6 million years in fifteen years). A/C units run the equivalent of over 46,000 miles each year, and oil and gas furnaces run about 126,500 miles per year. Ever heard of a car that can give you over a million miles of use and last for 15 years? 

We’re probably closer to inventing hovercrafts. We expect our HVAC systems to perform ten times harder and longer than our cars, so it seems logical to give them at least the same level of care and routine maintenance. All costly machines require check-ins and tune-ups, your furnace just as much as your car. It’s also important to remember that our harsh New England winters are just as tough on our furnaces as they are on us! Lack of yearly maintenance and service will lead your HVAC system to overwork itself, potentially causing damage to the system and increasing your energy bills. A broken-down furnace can also lead to safety issues and other hazards, such as burst pipes, especially when you’re not there to recognize the threat. We can only expect so much from a system that hasn’t been cared for, and we certainly shouldn’t seek peak performance from it without that regular maintenance! Tasks as simple as having the filters changed on your furnace – which costs about 1/3 the price of an oil change on your vehicle – can ensure higher efficiency from your system, increase its lifespan, and lower your energy expenses.

Annual maintenance on your HVAC system can prevent costly, premature breakdowns, saving you money in the long run. Heritage offers a Clean & Tune service, during which an HVAC professional will ensure your system is running at optimum safety and efficiency. Included in the gas furnace inspection is the changing of any standard filters and completing a carbon monoxide test. During the inspection of an oil furnace, technicians will change any standard filters, the oil nozzle, and the pump strainer. If you want your furnace or air conditioning system to continue performing at peak condition for years, you should sign up for our Maintenance Value Plan (MVP). The MVP guarantees your yearly safety inspection and cleaning of your furnace. As an MVP member, you’ll even receive a reminder call when your maintenance is due, not to mention priority service and discounts for any other visits you may need throughout the year!In addition to providing you control of the climate inside your car, truck or SUV, many Heating,

HVAC System Warning Signs Don’t hesitate if you think something is wrong with your HVAC system. If your A/C system doesn’t cool properly, your fan/blower doesn’t work, you hear loud noises when you turn your A/C on, or your vehicle stalls roughly or runs hot and overheats when you turn on or use the A/C, bring your car in today.

Other signs to watch for include: water on your vehicle’s floor or rugs, unusual odors from interior vents, faulty dash controls, or malfunctioning heater, vents or defroster.

State-of-the-art HVAC system for Shanghai auto factory During the design phase of a new automobile manufacturing factory in Shanghai, China, ITT’s Bell & Gossett unit was called in to resolve problems with the site’s heating, ventilation and air conditioning (HVAC) system. The result was an advanced and efficient set of pump sensors and controllers that power the large industrial facility’s HVAC system.

Shanghai General Motors Company Ltd. (SGM) is a 50-50 joint venture with U.S. auto giant General Motors and Shanghai Automotive Industry Corporation Group (SAIC), the leading passenger car manufacturer in China. The largest automotive joint venture in China, Shanghai GM was formed in June 1997. It manufactures a family of Buick products, as well as engines and transmissions. Shanghai GM is fully supported by a network of sales, aftersales and parts centers. Shanghai GM has an annual production capacity of 200,000 vehicles operating on three shifts.With sales success came the expansion of production facilities in Shanghai. SGM’s latest expansion is the South Plant. Covering 230,000 square meters, the plant is equipped with the most advanced automobile production line and equipment. Five main workshops adopt the management process of modularized design and flexible production lines to satisfy the variable requirements of the market by producing several different model cars in a single production line.

The new SGM factory produces luxury Cadillac model cars. The output of the new SGM factory is predicted to reach 200,000 cars per year.In the first phase of the factory construction, the HVAC system was equipped with pumps and common variable-speed controls. After tests during the design period, the HVAC equipment supplier was not able to resolve a number of unsatisfactory phenomena and performance problems. In order to resolve these system problems, the plant’s master designer began a process of engaging HVAC experts and investigating alternatives.Educating HVAC ProfessionalsIn China, ITT Bell & Gossett is viewed as a manufacturer, and as an educator and expert in HVAC equipment and system analysis. Every year, an instructor from Bell & Gossett holds seminars and advanced lecture series around China for HVAC designers and ITT Bell & Gossett distributors. This education is built on the 50-year history of the “Little Red Schoolhouse”, a center for HVAC education that ITT Bell & Gossett runs from its headquarters near Chicago.

The master HVAC system designer in charge of the SGM project was invited to attend the ITT Bell & Gossett seminar held in Nanjing. The principles, formulations and systems analysis shown in the seminar ultimately satisfied the master designer that ITT Bell & Gossett could resolve the HVAC system problems at the auto plant.After the seminar, discussion began with SGM regarding the new factory’s HVAC system. Piping layout drawings and system drawings were analyzed and ideas were shared to solve the HVAC design problems. Variable-Speed Drives Save EnergyPowering the huge HVAC system in the auto factory is the power plant, which takes up 5,000 square meters. This plant includes seven 2,000-ton chillers and three 400-ton chillers. Tying these chillers into the plant’s HVAC system are ITT Bell & Gossett’s primary and secondary systems with variable-speed design. Integrated into the new factory’s HVAC system is a large contingent of ITT Bell & Gossett pump systems, including nine large ITT Bell & Gossett Series VSCS pumps, 14 Series HSCS horizontally split pumps and 14 Series 1510 base-mounted end-suction pumps.

The pumps are controlled by the primary and secondary variable-speed system and provide the factory with excellent energy savings. Pressure sensors were placed in a number of positions throughout the plant; these sensors pass a signal to controllers. The controllers then change the frequency of the variable-speed drive to the pump’s rotation speed control, allowing an accurate flow in the HVAC system. In a comparison to the variable transmission that many cars are now equipped with, the ITT Bell & Gossett systems can provide the factory’s HVAC system with any capacity of flow by changing the pumps’ rotation speed. The initial cost of the variable-speed controller equipment is offset within short running period by minimizing energy expense.A local team including Fluidtech, the ITT Bell & Gossett distributor in Shanghai, and Alex Jiang, the ITT Bell & Gossett sales manager in Shanghai, assisted the SGM design engineers and successfully finished the HVAC primary-secondary variable-speed system design for the plant.
