HVAC Equipment Buying FAQ

Answers to the questions homeowners and contractors ask most when shopping for HVAC equipment online.

• Can I buy HVAC equipment online without a contractor license?

  Yes. Budget Heating sells to homeowners, contractors, and businesses. No license is required to purchase equipment. However, we recommend hiring a licensed HVAC technician for installation, as improper installation can void manufacturer warranties and compromise system performance. Refrigerant handling requires EPA Section 608 certification.

• How do I know what size HVAC system I need?

  System sizing depends on square footage, ceiling height, insulation quality, window count, climate zone, and building layout. A general guideline is 1 ton of cooling per 500–600 sq. ft. in moderate climates, but a proper Manual J load calculation provides the most accurate sizing. Our technical support team offers free sizing assistance. Call (813) 885-7999 with your project details.

• What is the difference between SEER and SEER2?

  SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency under older DOE test conditions. SEER2 is the updated metric adopted in 2023 that uses higher external static pressure during testing, producing a more realistic real-world efficiency measurement. SEER2 numbers are slightly lower than SEER for the same equipment because the testing conditions are more demanding. Both ratings indicate higher efficiency at higher numbers.

• Do your HVAC systems come with a warranty?

  Yes. Every system we sell includes the full manufacturer warranty, which typically covers parts for 5–10 years depending on the brand and product line. Some manufacturers offer extended warranty terms when the system is registered within 60 days of installation. We can provide warranty registration details for any product in our catalog.

• What refrigerant should I choose: R-410A, R-32, or R-454B?

  R-410A remains widely available and is fully supported for existing systems. For new installations, R-32 and R-454B are the industry's next-generation refrigerants, offering lower Global Warming Potential (GWP) and equal or improved performance. R-32 is commonly used in Goodman, Daikin, and Rheem product lines, while R-454B is being adopted by several major manufacturers. Both are A2L (mildly flammable) and require installation per current code requirements.

• How fast will my order ship?

  Most in-stock orders ship same-day or next business day from our Tampa, FL headquarters. Delivery typically takes 1–5 business days depending on your location. Florida and Southeast customers often receive orders within 1–3 days. In-store pickup is available at our Tampa warehouse at 6217 Anderson Rd., Tampa, FL 33634, Monday through Friday 7:30 AM – 5:00 PM EST.

• Do you offer contractor pricing or bulk discounts?

  Yes. Licensed HVAC contractors and businesses purchasing in volume can access additional pricing through our contractor accounts program. Call (813) 885-7999 or email sales@budgetheating.com to set up your account and discuss volume pricing for your projects.

• Do you offer financing on HVAC equipment?

  Yes. We offer financing through Affirm with rates from 10–30% APR depending on creditworthiness. Affirm lets you split your purchase into monthly payments directly at checkout. For larger commercial or multi-unit orders, contact our sales team to discuss additional payment options.

• What is a package unit and when should I choose one?

  A package unit combines heating and cooling components in a single outdoor cabinet, as opposed to a split system which separates the condenser (outside) from the air handler (inside). Package units are the standard choice for manufactured homes, mobile homes, slab-on-grade construction where indoor mechanical space is limited, and commercial rooftop installations. They connect directly to ductwork through a wall or roof penetration.

• Can I return HVAC equipment if I order the wrong size?

  We accept returns on uninstalled, undamaged equipment in its original packaging. Return policies vary by product type and manufacturer. Contact our customer service team at (813) 885-7999 before returning any equipment so we can assist with the process and help determine if an exchange is the better option. We strongly recommend confirming sizing with our team before ordering to avoid return situations.
