Frequently asked questions
-
How much are your maintenance plans?Planned Maintenance Agreement (bi-annual visit in Spring and Fall) – $269 first HVAC system | $210 each additional system
-
What does your maintenance service involve?Tune-Up (one-time visit): Visual inspection of all parts, flush drain, and check refrigerant charge. Planned Maintenance Agreement (bi-annual visits): Maintaining all records of equipment and manufacturer’s warranty status | Cleaning and visual inspection of all components | Test all major components, flush drain, and check/adjust refrigerant charge
-
Do I receive any benefits for being a maintenance customer?As a planned maintenance customer (bi-annual agreement), you receive a 20% discount off parts and filters along with priority service and loyalty benefits.
-
How often should I replace my filter?Filters range in different sizes and depth. The most common filter is the 1″ filter which should be replaced every 30 days to maintain your Indoor Air Quality. If you’ve made the investment in the AprilAire filters, then those should be checked and replaced every 6 months to a year.
-
Do you perform continuous annual background checks on your service and maintenance technicians?Dynamic Flow Heating & Air Conditioning uses AskTheSeal to perform annual backgrounds on all of our service, sales, and maintenance technicians whom might enter your home. AskTheSeal allows us the opportunity to send you an appointment reminder with a profile picture of the technician, when the last background check was performed, and a little biography about that individual. Call our Office Staff for more details.
-
How long does the maintenance service take?Inspecting from top to bottom will generally take about an hour per system for maintenance.
-
Is annual maintenance necessary for my system?Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control. Some manufacturers require you to perform at least a one-time maintenance per year to keep your registered warranty active.
-
Is system maintenance really necessarily in the winter?Recommended maintenance is twice a year, once on your AC unit and once on your heater. Having maintenance done only on your AC unit may prevent heater issues from being detected, making breakdowns of your system more likely and thus, saddling you with costly repairs.
It always seems that we experience problems at the worst possible time. Heating problems are no exception to that rule. It is always one of the coldest days of the winter, a time when we are expecting visitors or we have just had a tough day at work and were looking forward to relaxing at home. Sound familiar? If only we could do something that would get us some relief quickly and with minimal expense.
Perhaps some of these suggestions will help you on that fateful day when you realize your heat pump/furnace is not heating your home.
The display on my thermostat is not working. What can I do?
-
Check to make sure the batteries are good.
-
If so equipped, check the condensate overflow safety reservoir, located at your air handler/furnace, to make sure it has not filled up with water raising the safety switch. Suction out the water and re-install the switch. Do not attempt to run the air conditioner without the switch installed properly or water damage may result.
-
Check the breakers for your air conditioning system. There will be one for the indoor air handler/furnace unit and another for the outdoor condensing unit. If one of them has tripped it can be reset by first moving it to the OFF position and then back to the ON position.
What should I do if my Heat Pump/Furnace is not heating?
-
Check to see if the thermostat display is blank. If so, see the section “The Display on My Thermostat is Blank”.
-
Check the settings on your thermostat. If you want heating, make sure the temperature control selector is set below room temperature and the SYSTEM switch is on the HEAT or AUTO position. The FAN switch should be set to AUTO.
-
Check the air filter(s) for your air conditioner and replace if necessary.
-
Check the breakers for your air conditioning system. There will be one for the indoor air handler/furnace unit and another for the outdoor condensing unit. If one of them has tripped it can be reset by first moving it to the OFF position and then back to the ON position.
-
Homes with a gas furnace can check to see that the gas valve on the side of the furnace is turned to the “On” position. If the valve was off reset the breaker to the furnace by turning it off then back on again to reset any fault on the furnace. This will allow it to try and fire again if a demand for heating is present.
My outdoor unit makes a strange noise on cold nights. Is there any reason to be concerned?
Not typically, on a cold night a heat pump’s outdoor coil will freeze and it must be defrosted to maintain the unit’s heating efficiency. During this process the system will shift modes and may make some loud whooshing noises.
I think my outdoor fan is bad. It keeps going on and off in the winter. Is this normal?
Yes, this is typically associated with the defrost cycle on a heat pump and is part of the normal operation. It may also occur on certain model units when heat is running and the temperatures are slightly warmer inside and outside.
​
I have seen smoke like my outdoor unit is on fire in the winter, but it goes away quickly. Is there reason to be concerned?
No, this is typically occurs when the unit is in a defrost cycle. As the ice on the outdoor coil melts it will produce steam. The steam will rise from the unit and when the fan turns back on at the end of the cycle a burst of steam will rise from the unit all at once.
​
When I go outside, there is standing water at the bottom of my unit. Does my unit have a leak?
No, following a defrost cycle the melted ice will cause the area surrounding the outdoor unit to be very wet at times.
​
I know I need to do a maintenance in the summer, but do I need to do a maintenance in the winter as well?
Yes, not only do we use our air conditioners all year long but many of us use a heat pump for our heating needs. If the unit is running inefficiently the costs for cooling and heating needs will rise. Without twice per year maintenance on your system you may be spending more money to heat and cool your home.
​
What temperature should I set my thermostat to for cooling and heating?
It is best to set the temperature to a setting that is comfortable for your individual preferences. Typically, most people are comfortable between 78-80° for cooling and 68-70° for heating.
Following any problems experienced with your heating unit we recommend that you do schedule a service visit with a professional to ensure that your system is operating properly and that there are no safety concerns with the operation of the equipment that you may have overlooked. Most of the repairs listed are only offered as a temporary solution until a professional can assess the safe operation of your equipment. This is especially true regarding any of the above instances where an electrical problem was the cause for the failure.
