Find the label on the outer surface 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 based on the manufacturer. Warranty terms and conditions vary by manufacturer and the installing company. Donelson Air Service Experts 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 how old your equipment is or manufacturer warranty status.
Noisy heating and cooling equipmentincrease sound pollution.While no monetary
savings are tied to less sound in your home, the
sound rating of a cooling system can have a considerable effect on
comfort and enjoyment of your Nashville home. The sound level of an
air conditioner or heat pump depends on a variety of factors,
such as the
equipment, and the degree
to which the compressor is insulated can contribute to the
amount of noise it makes.
many heating and cooling systems made today are quieter than ever before, it's a good idea to compare sound
ratings when evaluating a new
air conditioner or heat pump,
particularly if the equipment location is near bedrooms or living rooms.
A Service Call fee is a charge for the expense associated with the time and travel to diagnose, inspect and deliver expert recommendations for a home's heating or air conditioning system by a certified professional technician. Coupons for the Service Call fee can often be found on our web site, in the Yellow Pages, or by email when joining our Email Club at the bottom of this page.
A popping noise is a typically sign of an under-sized duct design. It
may have to do with 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 provide a written recommendation. Improper duct work layout can be attributed to a variety of ventilation and air quality problems, including:
- loud banging noises
- higher energy usage
- lowered life of the system
- uneven heating & cooling throughout your home
- damaged compressor in summer
- overheated unit in the cooler months
In addition, if your ductwork is the wrong size you may have other problems, such as leaky ducts and poor layout that impacts airflow. In humid states this can cause mold growth within your ductwork.
answer is, typically, yes. Here's why.
System Design: All air conditioner and heat pump outdoor units
are specially constructed
to work with a matched indoor unit for peak
efficiency and performance. The effect of this matched equipment
is a harmonized,
top-performance team that ensures dependability and efficiency. Air conditioner
and heat pump outdoor units may ”run” with indoor units other
than those for which they have been specifically fabricated;
however, the result
would be a definite compromise in system performance.
the years, indoor blower coil
units have undergone numerous design advances — especially in the areas of air handling
performance, filtering efficiency and operating sound levels. A new outdoor unit will also incorporate the latest
Cooling And Heating Efficiency: The cooling and/or heating
efficiency ratings that are presented
for an air conditioner or heat pump are based on their performance as matched
systems. While changing only the outdoor unit may give you improved efficiency when compared with your old system, but efficiency
will suffer from what it was designed to be, and your savings will
be less than with a matched system.
Age: If an air conditioner or heat pump is 10 years old or more
and needs to be replaced, the
indoor unit is likely just as old and has been subjected to the same amount of degradation. Substituting both units
means you won't have to change the indoor unit in just a
short time… you'll have many years of efficient
Warranty: A new system also delivers you a new
product warranty. Replacing
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
Bargain: At first glance, changing only the
outdoor air conditioner or heat pump may appear to be a deal. 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 you benefit from
efficiency, reliability and comfort for years into the future.

You probably wouldn't purchase a brand-new car and assume to not ever have to add air to the tires, change the oil and examine any unfamiliar noises. Your home comfort system is like 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 experience complications and become less 'fuel' efficient over time.
are many possibilities that can trigger your HVAC system to
freeze up; many of
them usually need to be corrected by a professional technician. Determining
the air filter is clean or replaced and confirming the airflow is not restricted are about the only things
a homeowner should safely identify
or handle themself.
refrigerant: Sometimes, freezing up is initiated 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. The age of the system and the type and location of the
leak govern the decision whether to have the system repaired or
evaporator coil: Over time, the evaporator coil will become dirty. When this happens,
the results are similar to those of having a dirty filter. Gradually
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
blower motor or relay: A blower motor operating at the wrong 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. Either way, you will need to contact your local Service Experts
sales and service center to correct the problem.
that your system was freezing due to a dirty air filter, after replacing or
cleaning the filter, you can expedite 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
the system settings back to normal. If the system refreezes, contact Donelson Air Service Experts in
Nashville to solve the problem.
you are changing
your Nashville area home air conditioner, furnace or heat pump, it is the
right time to also install a new zoning system to fix
hot and cold spots or special temperature requirements in the home.
When your new comfort equipment is coordinated by a zoning
system, you will gain customized temperature
control in each zone.
is also a
great idea for new homes since the system can
be installed during construction. If you are investing in 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.
