DIY HVAC Prep in Arizona for Winter Warmth and Efficiency

Before the first hard freeze hits, take a weekend to run through these simple indoor and outdoor HVAC checks:

Whether you have a furnace, heat pump, or boiler, be sure to turn your heating system on during a mild September or October day. Let it run for 10 to 15 minutes to confirm it is operating.

Test Your Heat

Waiting until freezing weather to test your equipment puts you at a disadvantage. If you discover a problem and can’t get a repair for a week or so, you’re in for some frosty nights.

Testing your HVAC also helps burn off any summer dust in the system and ensures your heat pump’s reversing valve is working.

Replace Your Air Filter

A clogged filter chokes airflow, forces your heating system to work unnecessarily hard, and drives up your energy bills in Tucson, AZ. Replace your dirty air filter with a fresh one and inspect it throughout the winter.

If you own a mini split, you are likely washing the primary filters every month, and possibly more often if you have pets or allergies. Remember to replace any disposable secondary filters.

Check Your Whole-Home Humidifier

If your system includes a whole-home humidifier, switch the damper to the “Winter” position and replace the evaporator pad to add clean moisture to dry winter air.

Inspect Exterior PVC Vents

Check the outdoor PVC exhaust and intake pipes for your high-efficiency furnace or boiler. Clear away nests or leaves blocking the pipes. Blocked vent pipes can trigger safety shutdowns or, worse, dangerous carbon monoxide (CO) issues.

Clear Indoor Air Vents

Check that rugs, drapes, or furniture aren’t blocking supply and return vents throughout your home. Keep all supply registers open to maintain proper airflow, and use a vacuum attachment to clear dust and debris from the grilles.

Clean Around the Outside Unit

If the weather is still mild outside, hose dirt, grass clippings, and leaves off the outdoor coils of your heat pump or mini split compressor unit with a gentle spray of water.

Next, trim back foliage and remove any debris within 2 feet of the unit to allow for strong airflow.

Check Radiators and Floor Heat

Bleed the air out of your radiators using a radiator key if you notice uneven heating throughout your home. For radiant floor heating systems, check your manifold pressure gauges. Follow the manufacturer’s advice on the correct amount of pressure.

Protect Your Plumbing From Freezing Temperatures

You can easily prevent winter water disasters by tackling these simple plumbing chores:

Test Your Sump Pump

Winter thaws put massive pressure on your basement. Pour a bucket of water into your sump pit to ensure the pump turns on immediately, clears the water, and shuts off properly.

Disconnect and Drain Outdoor Hoses

Unscrew all garden hoses from your exterior spigots. Drain any remaining water from the hoses and coil them up for storage.

Drain and Shut Off Outdoor Spigots

Locate the interior shutoff valve that runs to your outdoor hose bibs. Turn that valve to the “off” position, then open the spigot to bleed out any trapped water.

Install Insulated Spigot Covers

Slip inexpensive insulated foam covers over your outdoor faucets to shield them from biting winds and low temperatures.

Insulate Exposed Pipes

Wrap vulnerable water pipes in unheated areas, such as crawlspaces, uninsulated garages, or exterior walls, using foam pipe insulation sleeves.

Set Your Thermostat Wisely

Never turn your heat completely off when you go out of town.

Consumer Reports notes your thermostat should be set to 55°F at a minimum to avoid frozen pipes when you are away from home during cold weather.

Open Cabinet Doors

During severe cold snaps, open the doors beneath your kitchen and bathroom sinks on exterior walls. This brings warm indoor air near the supply lines and prevents freezing.

Why You Should Schedule a Fall Tune-Up in Tucson, AZ

By scheduling a professional heating system inspection and tune-up every fall, you prevent breakdowns and gain peace of mind. It is the single best investment you can make in your home.

Here’s what you can expect from a professional heating inspection:

  • Catches Issues Early: Technicians look for cracked heat exchangers, gas leaks, and electrical shorts that can release toxic fumes or start fires. They also prevent minor issues from becoming significant problems that need costly repairs.
  • Restores Peak Efficiency: Calibrating controls, cleaning burners, and checking refrigerant or combustion levels ensures your system uses less energy to heat your home, lowering your monthly utility bills.
  • Extends Equipment Lifespan: Regular professional HVAC maintenance prevents premature wear, adding years to your heating equipment’s lifespan.
  • Validates Your Warranty: Many furnace and heat pump manufacturers require proof of annual professional maintenance to keep their parts warranties valid.

Why You Should Schedule a Plumbing Inspection

Autumn is a fine time to schedule a plumbing inspection, especially if your system hasn’t had one in the last three to four years.

A plumbing checkup can catch tiny leaks before they cause rot, mold, or flooding. Flushing your water heater can boost its efficiency, and identifying worn fixtures or clogs now can avoid emergency repairs down the road.
