HVAC Tips

Buying central AC isn’t just about brands or tonnage. This guide shows you how to choose the right system in 2025 by starting with Manual J load calculations, checking ductwork, and comparing SEER2/EER2 efficiency ratings.

If your HVAC is new but rooms still feel stuffy, the problem may be duct static pressure not the equipment. This guide explains static pressure in simple terms, shows why undersized returns choke airflow, and outlines how to size ducts, grilles, and filters for true comfort.

Insulation and air sealing don’t just shrink your energy bills they change how your AC should be sized. This guide explains how envelope upgrades reduce cooling loads, why oversizing gets worse after insulation, and how to right-size equipment for steady comfort and long-term savings.

Design temperatures 99% for heating and 1% for cooling are the backbone of precise HVAC load calculations. They reflect real climate data, not record extremes, and help right-size equipment for comfort, efficiency, and code compliance.

Replacing your HVAC doesn’t have to drain savings. By stacking rebates, using smart financing, and choosing the right size system, homeowners can see energy savings that beat their monthly payments from day one.

In 2025, homeowners can stack federal tax credits with state and utility rebates to cut thousands off cold-climate heat pump installs. This guide explains what’s allowed, what’s not, and how to plan your upgrade so you don’t miss paperwork, deadlines, or eligibility.

Tired of hearing that “gas is always cheaper” or “electric is always greener”? The truth depends on your climate, energy rates, and home setup. This guide busts the biggest gas vs. electric furnace myths, with real numbers, safety insights, and practical tips so you can choose confidently before the next cold snap.

The SEER2 standard brought more realistic efficiency ratings in 2023 but it’s just the beginning. Over the next decade, expect SEER3, SCORE, and SHORE metrics that grade systems under real-world conditions like humidity, part-load operation, and grid demand.

High-efficiency AC promises big savings, but real payback depends on your climate, energy rates, and ductwork. This guide breaks down true ROI with residential and commercial case studies, simple payback math, and pro tips on when to choose high-SEER2 vs. standard systems.

Vaulted ceilings look stunning but they change how your AC should be sized. This guide explains why tall rooms need more BTUs, how to adjust square-foot rules for volume, and which mixing strategies (fans, high returns, register aim) keep temperatures even from couch to loft.

Internal heat gains people, appliances, lights, and electronics add hidden loads that can overheat kitchens, offices, and bedrooms. This guide shows you how to estimate them with simple math, schedule them realistically, and right-size HVAC equipment for real-life comfort and efficiency.
