Santa Rosa. Our newest partner family, the

for your part in helping us to make
homeownership for our partner families a reality.

Hi Matt,
I want to thank you and Neal for the wonderful job setting up the radiant heat
on both the tenant’s and my parent’s units, as well as, the central heat on our
unit. More importantly, I appreciate your quick prompt friendly response time,
whether it’s because the plumber accidentally broke the radiant tubing or the
water heater (therefore the radiant heat) went bust on us. You guys are true life-
savers, especially since accidents happen when the weather is at its coldest!
Lastly, thanks for returning my phone calls and answering all my heating
questions.
Please feel free to use as referrals.
Sincerely,
Unhei Kang and Ben Khoo

I was doing an extension on my house and everyone knows it's a nightmare
finding reliable contractors for plumbing, electrical, HVAC and so on.  I've
called several HVAC businesses, but 88HVAC was referred by several people
that used them and they were happy with them.  They showed up when they
say they would.  They are friendly and knowledgeable, I've call several times
asking questions before I they were going to place the equipment and the
estimated time of when they can do the job and it was in a few days.  I told
them I was planning to add a second level in the future so they installed the
equipment that would accommodate my future second level addition. The cost
was very reasonable compared to other places I called for the same
equipment.    I've also recommended them to several co-workers and family
and they were very happy with 88HVAC.

Veasna L.- 4-2011 .Just bought a home less than
six months ago in San Lorenzo. Upon having the
dreaded home inspections done, it was brought to
my attention that my furnace was shot, along with
most of the ducting. I was stuck with using electricity
guzzling space heaters in each room to keep my
significant other and myself happy. After talking to a
few customers of mine about how cold it has been,
and how it's no fun living in a cold home... I was
fortunate enough to bump in to 88hvac(Matt)! Matt
walked me through all of the steps that it would take
for his crew to do the job right. 88Hvac showed up
right before I left for work, and COMPLETED the job
just as I was off work. I got home, and was amazed
at how there was HEAT coming out of the vents. I
had a smile from ear to ear. Nothing like coming
home to a welcoming warm home. Maybe I can
make it to work on-time now, since it wont be such a
drag to crawl out of bed.
I told 88hvac that I wanted done once, and done
right. I didn't want any shortcuts, I just wanted to "set
it and forget it". I wanted the heating system to be
worry free for years, and maybe the next owners to
come. He assured me I would not have any worries.
I'm also amazed at how CLEAN of a job they did. I
wish I could give 88hvac 10 stars, instead of 5. But
you know what, I can.
I rate 88hvac TEN STARS

My wife and I built a new home in Mountain View
three years ago that features a combined radiant
heating/domestic hot water system.  Our contractor
selected 88hvac to install the entire system.  Matt
and his team did a terrific job.  They got the system
up and running on time and for the agreed upon
price.  When other subs inadvertently punctured a
couple of the radiant lines in the floor, 88hvac was
back out to repair the damage at no charge, even
though they were not responsible.  The system Matt
installed features 8 thermostats that let us tune the
house for comfort and energy efficiency, and the
slightly warm floors are wonderful to walk on in bare
feet.  The house is always so uniformly comfortable
inside that we are often surprised by and
unprepared for cold temperatures when we head
outside. Just recently a gauge on the radiant system
indicated a lower than normal pressure which
concerned us because it can indicate a leak.  Matt
was out the next day to check things out.  He
explained that the water in the radiant system can
outgas over time, causing a gradual pressure drop.  
He inspected the system and topped off the
pressure, all at no charge.  When the pressure
again dropped a few weeks later, Matt was back out,
diagnosed a faulty gauge and replaced it, again all
at no charge.
I can't say enough about Matt and his team.  They
are honest, straight-shooting and professional, and
I highly recommend them.
"Matt handled our hvac work
very professionally. We had a
new heating and A/C system
installed to replace our aging
heating system. The work went
smoothly and matt always kept
an open and friendly line of
communication with us. I would
certainly recommend 88HVAC
to my friends."

Jose C. Menlo Park, CA Compliment
6/14/2009 .We had just finished a prefab home that came with a hi-velocity air
system last summer.  As the winter arrived, we found out the heating didn't
work.  We called back the on-site HVAC contractor responsible for hooking up
the system and performing startup.  They came out for several site visits and
could not figure out why the heating would not work.
The prefab factory then had 88HVAC come out and give it a try and they
resolved the problem on their first visit.  In about an hour, they identified two
conditions that were preventing the system from working properly.
I found them to be extremely courteous and knowledgeable about my HVAC
system.  I highly recommend them to any home or business owner.

.4/28/2009 .The rating says it all. We did a major renovation and worked with a
lot of subcontractors. Most of the folks who worked on our project were very
good. But 88HVAC is the one subcontractor that I have recommended to
everyone I know, without hesitation.
These guys came in midway through our radiant heat installation and finished
the job beautifully. After my first meeting with Matt, he made some design
recommendations to our system that saved me upwards of $5K for a more
efficient system that heats my entire house (rather than just a portion of the
house, as had been originally designed).   Bottom line - I got way more than I
expected, for lower cost.
Nelson L. San Carlos, CA
Matt and his team were fantastic.  Came out on day 1 for an estimate and
listened to our needs and desires.  He also provided excellent alternatives.  
We just had a straight forward high efficiency furance, A/C, and duct
replacement, even though they can do the more elaborate geothermal, radiant
and solar heating.  His team works fast, on-time and are very neat and clean.  
Matt answered all our questions and addressed our concerns with cold spots
and insulation.  Lastly, his prices are also very reasonable - the quote he
provided was one of the lowest of four bids we received.  Thanks again Matt
and I wouldn't hesitate to recommend you to my closest friends!

First and for most, i wanted to express that Matt and the team of 88hvac are
extremely Professional. They are very honest, and answered all my question.
They help me understand what i was investing my money in and how in the
long run, it was going to save me money and be more efficient am very happy
with the service and the customer service i got from them. I would recommend
all my friends and family to 88hvac, and if i ever in my mind had any doubt
about the company or their product, then i would never have writ en this review.
They are as good as they get. Thanks Matt and the 88hvac team for everything.
james s. San Francisco, CA
Matt was fantastic!  Came out to my place, diagnosed and fixed the
problem within minutes.  Even showed me how to fix it in the future, and
other steps I could take.  Also, super-nice guy.  Thanks!
We make customer service our first  priority. Take a look at what
others say about us.
We also believe in a strong community, we donate money and our
labor.
Jonathan G. Saratoga, CA 5/11/2011
I was referred to Matt at 88HVAC by a friend who owns a Matt
was professional and pleasant, and didn't make a mountain out
of a molehill. Having recently done business with a competitor, I
can tell you that the difference was night and day! Matt told me
to hang on to my current system (which was up and running
again in minutes), while others have told me that I need a new
system, which they would install for only some thousands of
dollars. It's sure nice to deal with an honest person who knows
his stuff!
