About this site

This is an independent, plain-English guide to home heating, cooling and air quality for homes in Raleigh, North Carolina and the surrounding area. We explain how systems work and what to check — we do not sell equipment and we do not collect enquiries on behalf of any contractor.

What we cover

Heating and furnaces, air conditioning, heat pumps, indoor air quality, seasonal maintenance and repairs. Every page is written from the point of view of someone living in a home with a system, not from a parts catalogue. Where a job is licensed trade work — refrigerant handling, gas pipework, combustion — we say so instead of talking you through something that should be done by a professional.

How we work

We explain causes rather than symptoms. A frozen coil, a furnace that short-cycles or a heat pump that feels cool all have reasons, and knowing the reason is what keeps a small problem from becoming an expensive one. We avoid invented numbers: efficiency figures, prices and schedules depend on the equipment, the home and the contractor, so we describe the ranges and the questions to ask rather than quoting a figure we cannot stand behind.

What we are not

We are not a contractor, and nothing here is a quote or a diagnosis for your particular system. We do not publish advertising dressed up as advice and we do not link out to sales pages. If a symptom in your home matches something described here, use it to ask better questions — then have the equipment inspected by a qualified technician.

Corrections

If something here is wrong or out of date, tell us using the contact page and we will correct it. Clear explanations help everyone make better decisions about their own home.
