Frequently Asked Questions

How do I know if I have an existing warranty on my furnace, air conditioner or HVAC system?

Locatethe label on the exterior of the system component for a manufacture date. If the equipment is less than five years old it may have a warranty, but also may not depending on the model. Warranty terms and conditions differ by manufacturer and the installing company. Mountainwest Service Experts Heating & Air Conditioning can verify the warranty status of your heating and cooling system via System Inspection. We also offer a Platinum PLUSTM Protection Plan for home heating and air conditioning systems, regardless of the equipment age or manufacturer warranty status.



Is sound an issue for heating and air conditioning?

Yes. Heating and cooling that make a lot of noiseadd to sound pollution.While no financial savings are tied to lower sound levels, the sound rating of a cooling system can have a serious effect on comfort and enjoyment of your Salt Lake City home. The sound level of an air conditioner or heat pump depends on many issues, such as the equipment, and whether the compressor is insulated or not can add to the amount of noise it makes.

Although most heating and cooling systems made today are quieter than they ever have been, it's a good notion to compare sound ratings when evaluating a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.



What is a Precision Tune-up and how much does it cost?

In addition to the comprehensive visual inspection that comes with our System Inspection, a Precision Tune-up also comes with a complete maintenance cleaning and lubrication of the heating or air conditioning equipment components. Find out more here about Mountainwest Service Experts Heating & Air Conditioning’s Precision Tune-up steps . The fee for a tune-up changes depending on the season, and may generally fluctuate from $69 to $159. Printable coupons with seasonal discounts on tune-ups can often be found on our Coupons page.



What's causing my duct work to pop when the furnace starts or stops?

A popping disturbance is a typically sign of an under-sized duct design. It may be attributed to greater air flow than the duct work is able to manage. Have a qualified company analyze your home’s ventilation system for proper design and recommend adjustments. Improper duct work layout can be attributed to a number of ventilation and air quality problems, including excessive noise.



When substituting the outdoor unit, should the indoor unit also be changed?

The answer is, most likely yes. Here's why.

Matched System Design: All air conditioner and heat pump outdoor units are specificallyfabricated to work with a matched indoor unit for optimal efficiency and performance. The outcome of this matched equipment is a harmonized, top-performance team that ensures dependability and efficiency. Air conditioner and heat pump outdoor units may "work" with indoor units other than those for which they have been preciselyintended; however, the consequence would be a definite compromise in system performance.

Design Advances: As research has improved, indoor blower coil units have undergone numerous design advances — especially in the areas of air handling performance, filtering efficiency and operating sound levels. The latest outdoor unit will also incorporate the latest design advances.

Higher Cooling And Heating Efficiency: The cooling and/or heating efficiency ratings that are posted for an air conditioner or heat pump are based on their performance as matched systems. While changing only the outdoor unit may outcome in improved efficiency compared to the old system, it will not be as efficient as it was designed to be, and your savings will be lower than with a matched system.

Equipment Age: If an air conditioner or heat pump is 10 years old or more and is ready for replacement, the indoor unit is likely just as old and has been subjected to the same amount of degradation. Changing both units means you won't have to replacethe indoor unit in a short time period… you'll have more years of efficient service with both units.

New Warranty: A new system also delivers you a new product warranty. Changing the indoor unit together with the outdoor unit results in peace of mind, knowing that the new warranty covers the entire system for the same period of time.

A Bargain: At first glance, changing only the outdoor air conditioner or heat pump may appear to be a savings. But, when you consider the lower cooling and heating efficiencies, decreased reliability and high cost of ownership that results, it's not such a bargain. Replacing an entire system may cost more, but the result is efficiency, reliability and comfort for years into the future.



Why don't you charge by the hour?

Similar to a value menu at nearby restaurants, charging a flat rate cost as opposed to an hourly chargeprovides more value for our customers because everything is included, the pricing is up-front, and it does not get modified. Regardless of the cost of parts or the time it takes to finish the repairs, the price will not change. This reason is one of many why Mountainwest Service Experts Heating & Air Conditioning is the most trusted name in Salt Lake City.



Why is it important to have regular maintenance on my home comfort system?

You probably wouldn't get a brand-new car and plan to not ever have to put air in the tires, change the oil and check out any atypical noises. Your home comfort system is the same as your car’s engine, it’s a mechanical device with a motor, electrical components... and even fuel. So it is essential to have routine maintenance of your home comfort system by a qualified technician. If not properly and routinely maintained, even the best heating and air conditioning equipment could cause problems and become less 'fuel' efficient over time.



Why is my AC system freezing up?

There are an abundance ofitems that can trigger your HVAC system to freeze up; most of them usually need to be corrected by a professional technician. Making sure the air filter is clean or replaced and making sure the airflow is not restricted are about the only causes a homeowner should safely identify or handle themself.

Low refrigerant: Sometimes, freezing up is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. How long your system has been operating and the nature and location of the leak govern the decision whether to have the system repaired or replaced.

Dirty evaporator coil: In time, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter. Increasingly you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately. You will need to contact your local Service Experts sales and service center to fix the problem.

Defective blower motor or relay: A blower motor running at an improper speed or not running at all can cause freezing. It can also be sporadic, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next. In either case, you will need to contact your local Service Experts sales and service center to correct the problem.

Should you find that your system was freezing due to a dirty air filter, after replacing or cleaning the filter, you can speed up the thawing process by turning the system off and then turning on only the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, turn the system settings back to normal. If the system refreezes, contact Mountainwest Service Experts Heating & Air Conditioning in Salt Lake City to solve the problem.



What is a Zoning System for a heating and air conditioning system?

Zoning Systems separate your home’s duct work into individual comfort areas, providing for independent temperature control in distinct areas that need specific temperature conditioning.

For example, a large living room with large bay windows may retain too much heat in the summer and feel too cold in the winter. A Zoning System will deliver more conditioned air to this large, sun-drenched area to help offset the heat gained or lost through the windows. A different example of areas that could benefit from Zoning might be a nursery, home theater or music studio, where different temperatures may be needed in each room for the comfort and enjoyment of the people occupying these rooms. Today's families have different lifestyles and comfort needs. Perhaps you have a home office that needs extra conditioning during the day and none at night. Or you only use the upstairs or back bedrooms when guests visit. Whatever your needs, a zoning system can maintain each area of your house at the perfect temperature for you and each family member.

Mountainwest Service Experts Heating & Air Conditioning provides free estimates and a complimentary consultation on Zoning Systems, call 385-399-0280 today if you think a new Zoning System could help solve your home comfort challenges.



When should I install a Zoning System?

If you are modifying your Salt Lake City area home air conditioner, furnace or heat pump, it is a good time to also install a new zoning system to fix hot and cold spots or special temperature needs in the home. When your new comfort equipment is matched with a zoning system, comfort is enhanced throughcustomized temperature control in each zone.

Zoning is also a great idea for new homes since the system can be installed during construction. If you are buying a new home, check with your builder about a zoning system. It could make the difference between just enjoying your new house and being truly comfortable in it.

Can indoor air be hazardous to your health?

Absolutely. Exposure to air pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90 percent of their time indoors, making indoor air quality (IAQ) a critical component of home comfort. Many common household items contribute to poor indoor air quality. Compounds found in carpeting, furniture, upholstery and drapery fabric constantly emit fumes. Other sources of pollutants can include cleaning agents, paints and personal care products. The tight construction of today's homes also contributes significantly to poor IAQ. Things like weather stripping and storm doors are designed to save on energy costs. However, they also prevent proper ventilation by keeping indoor air in and outdoor air out. The result can be a buildup of contaminants within the home.

Poor IAQ can contribute to several health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants within the home can cause homeowners to suffer from flu-like symptoms such as headaches, nausea and respiratory irritation. Additionally, two existing health problems that can be helped by improving indoor air quality are allergies and asthma. By removing airborne dust particles, the amount of exposure the respiratory system has to them is reduced. Proper ventilation also plays an important role in improving indoor air quality, helping to reduce the concentration of pollutants inside the home.



How can I find carbon monoxide in my home?

The best method of detection is to use a carbon monoxide detector indoors. A carbon monoxide detector is like a smoke alarm. It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected. Ideally, you should have one detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are best when used in combination with a service plan. Call 385-399-0280 for a complimentary consultation about purchasing a carbon monoxide detector.



How can I eliminate indoor odors?

You may have tried to cover up indoor odors by spraying air fresheners or lighting candles. Unfortunately, these tactics only mask the odors, they don't get rid of them. These remedies may in fact negatively affect indoor air quality from chemicals that cause allergic reactions or eye irritation for homeowners.

Bacteria, dust mites, animal dander, cat saliva and mold may also be roots of your home's odor problem. One method to purify the air is installing germicidal (UV) lights in your home, which helps kill odors and inhibit the growth of biological contaminants, sterilizing surfaces in the HVAC system. They also purify the air, preventing the growth of contaminants. The UV lights are installed to work with your home comfort system.

Sometimes poor ventilation is also a cause of unpleasant odors. Moisture condensation on walls windows and stuffy air are signs of poor ventilation. A qualified Mountainwest Service Experts technician can inspect your home comfort system to determine if this is indeed the problem. The technician can also inform you how to solve the ventilation system’s ability to adequately circulate and ventilate indoor air.



How do I choose the right humidifier?

An excellent way to choose the correct humidifier is by having a home health report performed by Mountainwest Service Experts. Every dwelling is different, and every family is different. So, every humidification need is also different. There are a few factors you should take into consideration when purchasing a humidifier for your home, Mountainwest Service Experts can help you understand and consider these criteria.

Consider size. A humidifier's capacity, or the amount of moisture it can dispense in a given time, should match your particular household's needs. The capacity is measured as gallons per day of operation. One method that is used to determine the correct-sized humidifier for your home is by multiplying the total floor area in by the ceiling height. We can provide you with this information and additional suggestions for knowing which type of humidifier will best suit you and your family’s comfort needs.

Consider cost. Consider not only the dollar amount of the humidifier, but also operating and maintenance costs. Some brands consume more energy than others, so choosing a model that is right for your home and budget is extremely important.



How do I know which indoor air quality product is right for me?

Every person and every home entails a different comfort need. The threshold of irritancy and triggers that affect people’s health and comfort combine to determine the proper solutions. High threshold levels may require simple solutions like a better air filter. Low threshold levels may require an air purification system for the reduction of triggers and irritants. With a Home Health Report Card, Mountainwest Service Experts can help you decide which indoor air improvement products are right for you.



How healthy is my indoor air?

According to studies created by the U.S. Environmental Protection Agency, exposure to air pollutants indoors can be 100 times higher than outdoors. Frequent dusting and vacuuming can help reduce the amount of dust and dust mites present in your home. However, not all airborne particles can be eliminated. Filtration devices can help eliminate particles that are too small to be picked up by vacuuming. Some filtration devices include UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs) and electronic air cleaners. A Home Health Report Card from Mountainwest Service Experts can help you decide which indoor air improvement products are right for you.

How much water does a humidifier use?

Depending on the product you choose and the size of your home, a humidifier may use from 1.5 to 12 gallons per day when the furnace is operating. The amount of liquid used is enough to raise the humidity to your desired level, but not enough to notice a difference on your water bill.
