Investing in a variable speed furnace or a variable speed heat pump may improve your home's comfort, but the right choice depends on your existing equipment, ductwork, budget, and heating and cooling needs.

How does a heat pump work in winter? Learn how heat pumps pull heat from cold outdoor air, use defrost mode, and keep your home warm in cold weather.

Welcome to Miller's Heating & Air, your trusted partner for heating and cooling in Vancouver, WA. In this article, we're going to clear up some common confusion about auxiliary heat and emergency heat in heat pump systems.

When it comes to heating your home efficiently, choosing the right size heat pump is crucial. A heat pump that's too small won't adequately heat your home, while one that's too large can lead to increased energy costs.

HVAC warranty paperwork can be difficult to interpret, especially when there are several documents involved. Different documents may list different coverage periods, registration requirements, and exclusions.

The process includes having a contractor look at your home, size the equipment correctly, review the existing ductwork and electrical setup, remove the old system, install the new one, test performance, and walk you through how everything works.

Your home loses heat faster when temperatures drop. That means your furnace or heat pump might have to run more often to keep your home at a comfortable temperature. Plus, utility costs rise from year to year. 

If you're used to a furnace, that might be strange. That’s because a furnace usually delivers hotter air in shorter bursts. A heat pump works differently. It moves heat instead of creating it through combustion, so during colder weather, it often runs longer to keep the house comfortable.

You can replace the filter. You can make sure none of your vents are closed. You can check the settings on your thermostat and clear leaves away from the outdoor unit. All of these things are worth doing.

Not sure if you have a heat pump? Learn how to identify your HVAC system, what a heat pump looks like, and how it differs from a furnace or AC.

Heat pumps rarely fail without warning.

If your system is running longer than it used to, if one room never gets to temperature, or if the outdoor unit is making more noise than it should, it may be an early sign that something in the system needs attention.. 

HVAC systems typically wear down slowly over time. 

It might start with a dirty filter, a weak capacitor, a clogged coil, or a refrigerant issue. You may not even notice it if the system is still running, which is the main issue with skipped HVAC maintenance. 

It might feel tempting to pick the cheapest quote when hiring an HVAC contractor, especially when you’re dealing with a big repair or replacement. But because your heating and cooling affect how comfortable you are at home and how much you’ll pay in the long run, it’s not really a one-time cost.

Some homes handle heatwaves pretty well. Some lose the fight by mid-afternoon.

Even if you have your AC on with the thermostat set low and air coming from the vents, the house might still feel warm and uncomfortable. And if by evening your system is still running and the upstairs bedrooms feel hot, you might be wondering.

Closing air vents won't always improve comfort and may increase HVAC strain. Learn why closing vents can reduce airflow and make hot and cold rooms worse.
