All Temp Heating & Air Conditioning in Baltimore: Residential HVAC Service with Load Calculations and Maintenance Plans

All Temp is a licensed HVAC contractor serving Baltimore homes with equipment installation, repair, and seasonal maintenance contracts. The company operates as a full-service provider rather than an emergency-only call shop, meaning it handles load calculations for new systems, discusses SEER ratings upfront, and offers recurring maintenance to reduce repair costs.

What All Temp actually does

All Temp handles heating and air conditioning for single-family homes and small multifamily properties in Baltimore. The company installs new systems, repairs existing equipment, and sells annual maintenance plans. It is licensed to pull permits in Baltimore City and County, which matters because Maryland law requires permits for most new HVAC installations and certain replacements; All Temp handles this paperwork rather than leaving it to the homeowner. The company also advises on when equipment can be repaired versus when replacement makes financial sense.

Services and pricing

Installation costs vary by system type and home size. A new central air conditioning system for a typical Baltimore rowhouse typically runs between $4,500 and $7,000 installed, depending on ductwork condition and whether existing infrastructure can be reused. A full heating and cooling system replacement (furnace plus air conditioning) usually falls between $7,000 and $12,000. These are ballpark figures; confirm current pricing directly since HVAC equipment costs fluctuate with manufacturing and supply conditions.

All Temp offers maintenance plans starting around $150 to $200 per year for a single seasonal visit (fall for heating prep or spring for cooling prep) and $300 to $400 annually for two visits per year. Two-visit plans typically include filter changes, coil cleaning, refrigerant checks, and safety inspections. Repairs are billed at an hourly rate, usually between $85 and $125 per hour depending on complexity, though All Temp typically charges a flat diagnostic fee ($75 to $150) that applies to the repair if the customer proceeds.

How All Temp compares to other Baltimore HVAC providers

All Temp's approach differs from chain providers like Ace Hardware's HVAC services or big national outfits. Chain services often quote higher replacement costs and push new equipment aggressively. All Temp tends to repair existing systems longer before recommending replacement, which appeals to budget-conscious homeowners but may mean longer waits during peak season if the company is full on maintenance contracts.

Local competitors like Huff's Heating & Cooling and Klein & Sons also serve Baltimore and often have similar pricing structures. Huff's holds an A+ Better Business Bureau rating and runs more promotions; Klein & Sons emphasizes commercial work but handles residential calls. All Temp occupies the middle ground: not discount-priced like some fly-by-night operators, not premium-priced like luxury-positioned firms, and focused on keeping existing systems running rather than upselling replacements.

Choose All Temp if you want a contractor who will load-calculate a new system properly (sizing HVAC to home square footage and insulation, not just guessing), explain SEER ratings in plain terms, and stand by warranty claims. Choose a larger chain if you need same-day emergency service guaranteed year-round; All Temp's response times extend during summer cooling season and winter heating season.

Who All Temp suits and who it does not

All Temp works well for Baltimore homeowners with aging but still-functional systems who want to extend equipment life through maintenance, or those replacing HVAC who prefer a contractor who will assess load rather than auto-upsize. It suits people who value a local operator over national franchises.

All Temp is not ideal for homeowners seeking 24/7 emergency response or those in urgent need of same-day service in peak season. It is also not the choice if you need a contractor willing to install systems below code or skip permitting paperwork; All Temp follows Baltimore regulations strictly.

What the first visit involves

A first-time call typically results in a phone consultation to describe the problem (no heat, weak cooling, strange noises, age of equipment). All Temp will schedule a diagnostic visit, during which a technician inspects the system, checks refrigerant levels, tests controls, and assesses the furnace or air handler. If repair is possible, the tech presents an estimate. If replacement is needed, All Temp discusses system options and SEER ratings, then quotes installation including labor, permits, and haul-away of old equipment.

Hours, parking, and logistics

All Temp operates Monday through Friday, 8 a.m. to 5 p.m., with limited Saturday availability during heating and cooling seasons. The company is based in Baltimore and serves the city and surrounding counties; service areas extend into Howard and Anne Arundel Counties but may carry travel charges. Call ahead to confirm if your address falls within service range. Appointments are scheduled in advance; same-day calls are handled on a case-by-case basis. There is no walk-in service.

All Temp earns its presence in a Baltimore home services guide by handling load calculations and permitting correctly, not cutting corners on system sizing, and maintaining equipment to extend its working life rather than premature replacement. For homeowners tired of generic HVAC shops, it represents a local alternative rooted in straightforward practice.
