What Goes Wrong

Where rushed heat pump installs fall short

Skipping key steps at the start creates performance problems that show up every winter.

Undersized Aux Heat

A heat strip sized by guesswork leaves the system short on output when Colorado temperatures drop below 20°F.

Load-Calculated Strip Size

A full Manual J load calculation sets the auxiliary heat strip size to cover the actual worst-case heating demand.

Leaky Duct Losses

Connecting a new air handler to unsealed ducts bleeds conditioned air into wall cavities, cutting delivered efficiency by 20-30%.

Duct Inspection First

A duct inspection before installation confirms sizing and sealing, so the system delivers its rated airflow at every register.

Wrong Refrigerant Charge

An incorrect refrigerant charge at startup forces the compressor to work harder, shortening its lifespan and raising running costs.

Pressure-Checked Startup

A refrigerant pressure check during startup confirms the charge is within the manufacturer’s specified range before the job closes.

Thermostat Mismatch

A standard furnace thermostat wired to a heat pump can trigger the auxiliary strip unnecessarily, adding hundreds of dollars to winter bills.

Heat Pump Thermostat Setup

The thermostat is confirmed compatible with heat pump staging and auxiliary lockout before the system is commissioned.

System Scope

What a ducted air source heat pump install covers

From the outdoor condenser to the final airflow check, here is what the full installation includes.

Heat Pump Replacement

Swap an aging heat pump for a current-efficiency model.

Furnace & AC Conversion

Replace separate heating and cooling with one ducted system.

Thermostat Upgrade

Install a heat-pump-compatible smart thermostat.

Duct Repair & Sealing

Seal and resize ducts ahead of the new system install.

Ducted Heat Pump Systems

How an air source heat pump heats and cools your home

One system handles both seasons by moving heat rather than generating it, using your existing ductwork.

An air source heat pump moves heat between the outdoor condenser and the indoor air handler through a refrigerant line set. A reversing valve switches the flow direction, so the same system heats in winter and cools in summer. For Lakewood homes with existing forced-air ductwork, this is often a direct swap for a separate furnace and central AC.

Colorado winters can push outdoor temperatures low enough that an auxiliary heat strip is needed to cover the gap. Sizing that strip correctly requires a full load calculation, not a rule-of-thumb estimate. Older Lakewood homes may also need a duct inspection before installation to confirm the system can deliver the rated airflow without pressure losses.

After the outdoor unit is set and the refrigerant line set is connected, the system is charged and balanced. A startup test measures refrigerant pressure, airflow at each register, and thermostat response. The post-install check confirms the system runs at its rated output before the job is signed off.

Common Questions

Questions homeowners ask before getting a heat pump

  • Will a ducted air source heat pump work with my existing ductwork?

    It can, provided the ductwork is in reasonable condition. A duct inspection checks airflow, leaks, and sizing before the new air handler is connected. If modifications are needed, those are scoped and priced in the written estimate before any work starts.

  • How well does an air source heat pump perform in Lakewood winters?

    Modern variable-speed compressors maintain useful heating output well below freezing. At 5,500 ft, the key is altitude-adjusted sizing, a system sized from a sea-level spec sheet will underperform. The load calculation corrects for elevation before anything is ordered.

  • What happens if I keep repairing my old furnace instead of replacing it?

    Repair costs on aging equipment tend to compound. A furnace past 15 years typically loses efficiency each season, and a mid-winter breakdown leaves you without heat while waiting for parts. A replacement planned on your schedule avoids that scenario entirely.

  • How much does an air source heat pump cost installed?

    Installed cost varies with system size, duct condition, and any electrical work needed. The written estimate you receive before booking covers equipment, labor, and every identified add-on so the final number matches what you agreed to upfront.

  • How long does an air source heat pump last?

    With regular servicing, most ducted air source systems run 15 to 20 years. Installation quality and duct condition at the time of fitting are the biggest factors in reaching the upper end of that range.

  • Is an air source heat pump better than a separate AC and furnace?

    A heat pump handles both heating and cooling from one refrigerant circuit, so you maintain one system instead of two. For homes with existing forced-air ductwork, it is a direct replacement that removes the need for a separate gas furnace.
