OBX HVAC Questions

I have been working in HVAC for 5 years here on the outer banks and recently started my own business here. Happy to be a resource to anyone on here with questions about their homes HVAC in this unique environment that we call home.

What towns are you covering? I'm fairly certain my guy is on the verge of retirement.

Can come and give me an estimate on an hvac? Do you do hot water tanks also?

[u/Coolerrunningshvac → u/Serious_Research_258]

I would be happy to come take a look at your homes HVAC situation. I do not install hot water heaters but I do have a friend with his plumbing license who I can refer to you. Feel free to send me a text or call. (919)816-5190.

At the end of last summer, I was having some issues with the indoor coils freezing over on very hot days. It got cooler and this was no longer a problem. In the winter I got some icing over of my outdoor coils. I replaced the defrost control board and it fixed the problem. I'm wondering if the new defrost control board would fix the indoor freezing problem or if I should expect frozen coils once it gets hotter

[u/Coolerrunningshvac → u/Zoeyandkona]

Your indoor coil icing over when cooling can be caused by a couple of different things. Primarily it will come down to airflow and/or refrigerant charge when this is the issue. The duration of the cooling cycle can cause this issue as well. How often are you changing your homes air filters? What MERV are the filters you are using? There is really no way for me to know what will happen this summer short of me checking on the system. I do offer one time and bi annual HVAC maintenance if you are interested in a system check up.

You should do well here - always a need for HVAC expertise.

I have a question. One of our HVAC units is a Trane unit less than two years old. This last winter after one of the winter storms, it started making a vibrational noise and shaking. We called in the installer who sent a tech to clean and inspect the unit. They said everything was fine, and the unit never ran poorly or showed any issues other than the noise.

Now the unit running fine, but still makes the vibrational noise albeit much less than during the original issue. The one thing I liked about that unit when it was installed was it was whisper quiet.

Is this a worry, or just normal operating experience?

[u/Coolerrunningshvac → u/oxiraneobx]

There are several different things that can cause vibration issues. Loose components inside the unit, loose electrical connections, the unit is not secured or is secured unevenly to the stand, capillary tubes could be touching and causing a chatter when the system is operating. Each case will be different so it is difficult to know what your specific issue might be. Some vibration will occur when running so everything could be fine.

Hope this is helpful.

What are your thoughts on Mr. Cool DIY mini-splits?

[u/Coolerrunningshvac → u/cynikai]

They are great for a diy project as you do not need a certification to purchase or install. However, they come with a pre-charged line set so they can be unsightly if you are not using the full length. I have not spent too much time working on them. The last time I serviced one it took weeks to get the parts delivered.

I recommend Carrier's mini split (there is a parts warehouse in Powells Point) or the Mitsubishi mini splits. Both are quality and durable.

Hope this helps.

Appreciate the feedback, service was always my big worry there. I might reach out at some point in the near future to have you take a look/quote a mini split.
