HVAC Tips

Bigger isn’t better when it comes to HVAC. Oversized systems short cycle, waste energy, and wear out faster especially in today’s tighter homes. This guide explains how to right-size with Manual J, then plan for the future with modular add-ons, extra duct stubs, smart controls, and panel capacity for EVs or renovations.

Traditional thermostats react; adaptive controls predict. This guide explains how next-gen heat pump controls use forecasts, sensors, and machine learning to optimize compressor speed, airflow, and defrost timing in real time.

Your furnace is more than comfort it’s a trust signal for buyers. This guide explains how gas vs. electric systems (and heat pumps) affect resale value, what inspectors look for, and when to repair or replace before listing.

SEER2 isn’t just a new label it’s a better measure of how your HVAC system performs when ducts, weather, and real-world conditions push limits. This guide breaks down why SEER2 ratings dropped but accuracy improved, why variable-speed and inverter-driven systems keep homes comfortable under stress.

Confused about SEER2 ratings and AHRI certificates? This guide shows you how to verify your central AC system’s efficiency and ensure the outdoor unit, coil, and furnace are truly matched. You’ll learn what SEER2 vs. EER2 means, how to confirm your certificate online, and why utilities and rebates require it.

The old “400–600 sq ft per ton” shortcut oversizes most modern homes leading to short cycling, high bills, and poor humidity control. This guide explains why Manual J calculations beat guesswork by factoring in insulation, windows, infiltration, and climate.

Insulation and air-sealing aren’t just about comfort they set the load your HVAC must handle. This guide shows how tighter envelopes cut tonnage by 10–70%, improve humidity control, and lower both upfront and operating costs.

In Climate Zone 8, a furnace isn’t about comfort it’s survival. This guide walks you through choosing between oil and gas, preventing frozen fuel and condensate, and why modulating furnaces are the subarctic standard.

Sizing HVAC for multi-family buildings isn’t just “bigger equipment.” Shared walls, staggered occupancy, and diversity of demand mean the right system often looks smaller on paper but delivers better comfort and savings.

Cold-climate heat pumps change how your home feels in winter and how indoor air quality should be managed. This guide shows why traditional humidifiers underperform, how ERVs protect against dryness and condensation, and how to size MERV-13 filters without choking airflow.

Big HVAC changes arrive in 2025. This guide explains the new refrigerant ban on R-410A, what A2L systems mean for safety and installation, and how state rules on gas vs. electric are unfolding. You’ll see how to compare operating costs, plan electrical upgrades, and take advantage of tax credits and rebates.
