Buying & Selling a Home
The HVAC questions that show up alongside a real estate transaction: inspection findings, system age, warranties that may not transfer, and what to check the week you move in, before small surprises become July emergencies.
I have a home warranty. Do I still need an HVAC company?
Yes, as a second set of eyes. Warranty claims route you to whichever contractor the administrator assigns, and coverage disputes are common. When their contractor says 'replace' or a claim gets denied, an independent $89 diagnostic gives you your own written answer to push back with, or the confidence to proceed.
Just moved in. What should I check on the HVAC first?
Five things, ten minutes total: find the filter and save its size in your phone, replace it if you cannot see light through it, find the HVAC breaker in the panel, run both heat and cooling for ten minutes each before the season forces the question, and clear two feet around the outdoor unit.
How do I find out how old my HVAC system is?
The manufacture date is encoded in the serial number on the outdoor unit's nameplate. Text a photo of the nameplate and your thermostat to (661) 374-0624 and we will read you the age, model, and filter size for free. In Bakersfield heat, ACs typically last 12 to 15 years and furnaces 18 to 20.
How do I know if my HVAC system is still under warranty?
Find the model and serial number on the outdoor unit's data plate, then run it through the manufacturer's warranty lookup page; every major brand has one. Two catches decide most cases: many brands grant their full parts term only if the system was registered shortly after install, and warranties often shrink when a home changes hands. Check before paying for any major repair.
The new AC refrigerant is flammable? Is R-32 actually safe?
R-32 carries an A2L rating, the mildly flammable class, which sounds alarming until you read what it takes to ignite: a concentrated leak meeting an open ignition source, conditions modern equipment is specifically engineered to prevent. It burns so slowly it struggles to sustain a flame. Regulators approved it, every major manufacturer builds with it, and the scare version of this story is mostly a sales tactic.
What questions should I ask an HVAC contractor before hiring them?
Seven questions sort the field fast: Are you licensed with the CSLB, and what is the number? Will you pull a permit? Do you do a Manual J load calculation on installs? Is the quote itemized and flat? Are your technicians paid commission? What are the parts and labor warranties, separately? Are your prices published anywhere I can check? Every good contractor passes all seven without flinching.
The inspection report flagged the HVAC. How bad is it?
Usually less bad than it reads. Inspector language like 'at or near the end of its useful life' is a prompt for pricing, not a verdict. An $89 diagnostic turns the flag into a written answer: what needs fixing now, what can wait, and the repair versus replace math you can take back to the negotiating table.
