Heating, Air Conditioning, Fridge, HVAC/heating unit

Question
Only when it is coldest like overnight and early morning, when the temperature of the heat reaches what it is set at (68 or 70 degrees) on the thermostat, the heat is trying to shut off but immediatley comes back on.  The fan on the outside unit is running but as soon as it goes to shut down it starts back up before the blades even stop spinning and will do this constantly about every 15 seconds!  Thanks for your reply, I am worried about my electric bill being high or the whole unit needing to be replaced.  (We do have a heat pump and run on total electric, no gas.)

Answer
Lisa,
 I am onther expert here been on vacation.  I hope you have had someone out by now, but if not I can help you.  It sounds to me like your indoor air filter is clogged solid, the indoor fan is not running or you have a restriction in the refrigeration tubing.  When something like that happens on a heat pump...SHUT it off immidiately.  Then turn your thermostat to emergency heat and call a tech.  That will eliminate the outdoor unit and give you an electric furnace until you can get it repaired.  Those symtoms if left to run like that can ruin your compressor, or in other words, a new unit.
 Let me know if I can help you any more

Expertise

I am in Portland Oregon at Ben's heating 503-233-1779. I work days, so I can only answer early in the day or later in the evening. I only answer public questions for residential equipment. I am very well versed in gas, electric and heat pumps and will only answer residential applications. I have been known the past decade or so, by my employers as the guy you send when no one can figure it out. Trouble shooting is my special. I understand the physics behind air flow, refrigerants and electricity. I understand programmable t-stats, zone controls, economizers, fossil fuel kits and the engineering thought process in the wiring and construction of residential equipment

Experience

I was lucky enough to start in this field almost 30 years ago as an installer, for a company that installed the best duct systems I have ever seen, even to this day. The best ,as far as understanding the way air really flows through a duct system, from the return air to the very last supply register . They also had great pride and the duct work was put in, not only to last 50 years, but to look exceptional. Then as I started doing service work, I was again fortunate that I found a 3 year engineering class being put on be a man that was the educational director for the Entire united states for a society called " the Refrigeration Service Engineering Society " And for the next 3 years I schooled at night and practiced what I learned during the day, a great advantage over schooling and then trying to remember it years later.. Versed in duct design manual J heat gain/loss calculations.

Organizations
Refrigeration Service Engineer's Society

Publications
I have 2 inventions that have gone through the process and been recorded at the National Institute of Standards and Technology from start to finish and thus been invited to national innovation workshops by the dept. of Commerce and the dept. of Energy. They are waste heat recovery devices that N.I.S.T approved as valid and am currently looking for marketing partners to get this product into the hands of consumers and make a BIG difference in Energy savings for every Household and Eatery and take a big bite in the the peak hours power consumption that face our Utilities companies.

Education/Credentials
factory training in Lennox ,Rheem, Ruud ,Trane, Tempstar ,Carrier, Day&Night, Payne, Bryant, Coleman, Intertherm, York, Goodman, Ultra boilers, Unico, Mitsubishi,Sanyo, Taylor, Nicewonger, Navien. Associates degree in Refrigeration Engineering. Certified with Energy Department, Check-me Program, P.T.C.S (performance tested comfort systems ), have N.A.T.E. certifications in gas, a/c & heat pump.
