Get matched with top furnace / forced air heating system install or replace pros in Red Bluff, CA

"They did a thorough and complete job. They recommended items I hadn't thought about and cut back on portions of the job that were not necessary that saved me money by not doing. Both installers were very knowledgeable and friendly and came across as very trustworthy. Never had an AC work so well before."

"Keith came over for an estimate the previous Friday, took one look at our old tank water heater, and let us know what a liability it was.  We were then persuaded to go with a tankless water heater -- I have to say that I wasn't hot on the idea initially due to cost recovery being nearly impossible on them due to high installation costs having to rejigger the plumbing, add electrical, and update the venting.  However, we had decades of code violations which would have added up to a monstrous cost (especially for the vent) to replace with a normal water heater.  The NPE-240A that we were persuaded to purchase uses PVC venting, which is routable through older metal vents -- thus is a cost reduction over installation of new, up-to-code metal venting.
Note that Gallagher will have a promotional first-visit price.  If you don't sign the dotted line to purchase a major service from them on that first visit, the price may increase by several hundred dollars on the next visit.  That is a little bit of a pressure tactic and we would have done a bit more homework had we known of it.  However, in this case, we had a potentially disastrous situation on our hands with that 23 year old water heater and didn't much feel like tempting fate by checking with other contractors for their costs and quality of service.
 After Keith left, I began to do some additional research.  I came to find that flush valves are a huge convenience with tankless water heater.  They allow you to easily isolate the house plumbing from the tankless water heater, connect two hoses to the heater and a pump, and circulate a lime scale dissolving solution (such as house-hold vinegar) to remove the scale from the heater exchanger.  I was worried that the install wouldn't come with these flush valves.  I called Gallagher at 9am on a Saturday morning and asked if they would be installing flush valves.  The initial answer from the on-call plumber was no.  Fortunately, Keith provided his personal/work cell phone.  I called to verify the no answer.  He assured me that the flush valves would be installed (and yes, they were -- and high quality valves too; single ball-valve, cast in Italy!).  Thanks, Keith, for taking my call on your off day.  That saved everyone a lot of grief :-)  So my nerves were soothed and I waited patiently for Monday to get that old, possibly leaking, tank water heater out of my house.
 On Monday, two technicians came out on time (Travis and Chad).  I don't recall which one was the experienced plumber, but one of them was definitely new and needed the experience (we all start from somewhere).  Both set out to do their work and were fairly efficient.
Only one mistake of note was caught.  The lesser experienced technician did accidentally cut a hole through my gas furnace vent cap, believing it to be the water heater vent cap.  The mistake was caught, and some sheet metal was cut and the cap was repaired with some mastic and water repellant stuff.  I don't know if that's code but I suppose I'll find out when the code inspector visits to close the permit... certainly the last thing I need is CO entering the house because the cap was reinstall or repaired incorrectly.
The copper pipes were completely reconfigured, and even shortened (which is always good for water pressure and heat retention).  The PVC outlet vent was installed through the old vent and spray painted black.  It can hardly be seen from the highway.  The experienced plumber ensured that the system worked well at full firing.  He didn't have a Manometer that worked with the unit, so we didn't get our gas pressure tested.  He said that the inspector should be able to do that; should I have made him come back to test the pressure?  Well, it seems to work with the gas stove going, but I haven't had a chance or a cool day to test the furnace plus the water heater and the oven.  Backing up a bit, they did install an outlet into the water heater closet, tying into the bathroom electrical on the other side.
The final result looked nice; the valves were mostly positioned in an accessible way.  The hot water flush valve is a little hard to access with the gas trap in front of it.  But everything got insulated, and a bit of PEX tubing was installed for the condensation line.  That was also insulated, so UV degrading the PEX shouldn't be a problem?   The heater was installed in an exterior water heating closet with a vented outside door.  The condensation line was linked up with the A/C condensation line.  The A/C condensation seems to still make it out.  Bonus that the PVC was extended off my patio, but the condensation does now exit just behind the A/C unit. I've read that the Navien produces somewhat acidic condensation so I'm only slightly concerned that large amounts of condensation could cumulatively affect the A/C metal footings.  We'll see what the inspector says (I'll update this review after that is completed).
Overall, the experience was nice, and we were not bothered too much with the Gallagher membership plan like last time.  The techs were personable and willing to explain what they were doing.  They even let me see what a bad idea it is to have galvanized piping interact with copper piping.  Yuck!  It is nice to get rid of all those corroded galvanized stub outs between the old tank water heater and the main service to the house.  They didn't mind that I was looking over their shoulders the entire time; personally, I hate when others do that to me, so good on them.  The experienced plumber graciously repaired some of the busted out dry wall with some of my left over dry wall, which was great, and helped complete one of my DIY items.  Only other thing that comes to mind is, ensure that the techs clean the cold water inlet filter after testing the tankless water heater.  I had to do that myself (per the install instructions that came with the unit) and it had some debris from the performed work.  The tech did explain how to clean that out as it is regular maintenance for tankless water heaters.  He also let us know that there is an inlet air filter that is easily cleaned.
Good experience overall; a few minor (?) issues cropped up.  I'll update this review when the inspector checks on the work.   The heater works great, even without a recirculation line.  I'm much happier to be serviced by a tankless water heater!

** Update post-Inspections **

After waiting a few weeks, and inquiring Gallaghers about the permit, and then receiving it shortly after that inquiry, we had the City inspector over.  He found that the tankless water heater did not have a properly sized gas input.  He caught the fact that the gas line reduced down to 1/2" somewhere after the house furnace.  For some reason the old water heater and adjacent stove had 3/4" pipe connected to that 1/2" pipe.  The installers did not notice this as a potential problem.  The inspector was concerned that if the house furnace were going, there wouldn't be much left over for the house tankless water heater.  Thus he wrote up the install as needing 3/4" pipe all the way to the water heater.  He also detected a hint of natural gas smell in the water heater closet.  We pointed out that the house furnace roof jack had been damaged and repaired.  The inspector took a look and wasn't so sure that the mastic would hold up to the vent's output heat.  So the jack/bonnet would have to be replaced.

It took one night to get a plumber out to fix the gas leak.  It took 3.5 weeks to get plumbers out here to fix the inspector's red tag items for upsizing the gas line and replacing the vent bonnet.  We had called Gallaghers many times during those weeks and were told they would get the installers in touch with us to schedule repa"

"My daughters a/c went out when it was 100+ and I referred her to Ian whom I had the pleasure of working with for many years. It was after hours but he was willing to come out. I can't remember what the issue was but he was able to get her a/c back on line. He is a man of integrity and truly cares for his customers I recommend A&S for all your heating and air needs."

"Jed went above and beyond installing my new ceiling fan. He had to get some supplies and worked in my hot attic and made sure that it was wired correctly. This involved cutting through the old inside wood 2nd layer roof to get to the hidden electrical wires where he put a junction box and new wiring for the fan and light kit. He stayed longer than necessary and completed the job that night after working all day. He is a consummate professional and I will hire him again. through"

"After having countless issues with our A/C and heating unit, John fixed it during his first visit to our home and we have yet to experience anymore issues with our A/C and heating. Thank you for your service!"

"Do.n was on time and was extremely knowledgeable I was told by previous companies that my mini split was not repairable and suggested that I install a brand new unit. Not only did Don repair my unit he was very reasonable with the price I will only call Don Hays Heating and Air from now"

"Mega Power Electric is an excellent company to work with. Gary and his team are knowledgeable, honest, and will go out of their way to get the job done right. We installed panels and solar battery storage unit in our home and we're reaping the benefits of being clean and green."

"Professional staff and excellent work done! Jason took less than an hour to discover what the problem was with the evaporative cooler and install the new water pump - and this was during an extreme heat wave!! Jason was very courteous and I am very happy with his work as well as the minimal cost!"

"Energy Smart Engineering was amazing. They provided a quick response and appointment. The technician ensured that I understood everything going on. He had the problem fixed quickly and didn't leave until he was sure that the problem was fixed. I would definitley recommend they to everyone."

"David was a professional and did a very thorough job! He even went as far as to show me photos of my damaged system."
