Your Questions About Hvac Repair Costs

Jenny asks…

A home inspector said we need insulation on our HVAC coolant line? Can we do this ourselves? Or hire a pro?

Our house is under contract to be sold, so we are dealing with the inspection report at this point. Apparently, there is no insulation on the coolant line between the heat pump and the exterior of the house. Is this something we can do ourselves? We are facing other repair costs as well, so anything we can do ourselves would be great. This sounds fairly simple, but I could be wrong.

You can do it. Measure coolant line pipe thickness. Often 1/2inch piping.

At Lowe’s, go to the aisle where they have pipe insulation. Often near plumbing, of course. Sometimes near the HVAC filters. Also purchase some metal duct tape.

Get enough to travel from your AC coil (inside) to the outside condenser unit. Wrap the insulation around the pipe — being careful not to bend or kink. Wrap metal duct tape around the insulation to keep it intact. And around the pipe. Do your best to even insulate the part of the pipe that goes through the wall to the outside. Caulk any remaining gaps with silicone caulk or electrician’s clay.

At $100+ HVAC bill complete by YOU instead…. For $20 and an hour of your time.

Good luck.

Who is responsible for HVAC/oil bill?

I’m working with a buyer who has an accepted offer on a short sale property (vacant). We just had the inspection done today. The only portion of the inspection that couldn’t be completed was the heating/cooling system because the oil tank (above ground, in-basement tank) was on empty and because of this..the furnace’s pilot light was out. The inspector didn’t want to risk trying to re-light it and possibly cause an explosion (you never know) so he wrote in the inspection report that more oil needed to be put into the tank, and an HVAC repair person needed to come and check out the furnace. I called the listing agent, and not only did he deny that the tank was empty (he swore that he had been there the day before to check on it and it’d been half-full) but that himself, nor his sellers would be responsible for getting oil in the tank to complete the inspection..much less the cost of the HVAC or to have the inspector come back and a-ok it. Something smells fishy to me. I was under the impression that the listing Realtor is responsible for any and all components that need to be checked in an inspection, are in working order on the day of inspection. Why should my buyers, or myself, have to pay for this? If it means anything, this is in NY State.
“Realtor”..with all due respect, just because someone is a Realtor does not mean they know everything to do with every situation. Asking questions is how we learn in our profession. Your cocky attitude is not needed.

appliancerepairpros answers:

You are a Realtor and your posting this question here? You need to be talking to your broker and/or review the purchase contract. It’s the listing agent’s or seller’s responsibility. It’s the same as having all the utilities turn on. The buyer pays for the inspection so it’s his decision as to whether or not have the inspector return. The inspection is incomplete and there are probably some time constraints in the contract,so the buyer needs to make a decision. Take it as is or cancel the contract due to an unsatisfactory inspection.

Cost of replacing hvac for a 2300 sf two-story house?

looking to replace current system with a 13 seer ac 95% 70,000 btu gas furnace, also ducts need some work which was estimated at about $1000. got a couple of estimates, the better one being $7500 to replace the outside ac unit and the inside gas furnace and to repair the existing ductwork. the house is a 2300 sf two-story house in central California. is that a fair quote, or should i keep looking.

appliancerepairpros answers:

For that price they should do the install and replace all your duct work…a Goodman 4 ton 15 seer with a 95 % efficiency furnace is about 4145.00 plus tax installed including duct work included…..should cost about 1500 dollars to 1900 dollars per ton to install with new duct work…….this price could vary depending on unit…. I would get new estimates as i think this is high to just replace the units and do no duct work and then pay 1000 dollars more to fix your duct work……

John asks…

Looking 4 Hvac installers newton iowa, electricians same?

Hi, I am looking for Hvac installers who could install in the newton area, also electricians. You need to be certified. I would like american standard, trane, rheem, ruud bryant or carrier would be considered based on cost, I am having a hard time deciding who to go with so I am putting it on here. I would like high efficiency, my home is 960 sq ft ranch from 1958 and we will be having blown in installation put in attic to r 19 thickness. If you could help me out I would appreciate it. the electric needs a new range outlet, and our box needs rewired. the hvac system currently there will need removed and I would consider a repair contract? warrenty you know where you buy discounted services in return for it being checked out every year. I do not think the duct work needs replaced though I will have to look at it to see if it is square or not. thank you sorry I know this is odd but we just bought the place. my email is

I can’t help you find HVAC installers or electricians in Iowa, because I’m in California. However, the Iowa Division of Labor Services has an online database that can be searched for registered electricians or plumbers (including heating and air conditioning). Go to:!OpenForm

Regarding air conditioning, I recommend that you buy the most efficient (highest SEER) system that you can afford. The cost of energy will probably keep going up, and you don’t want to install a system that will soon be obsolete. I’ve got a high efficiency Bryant system that uses Puron, which is their trade name for R-410A refrigerant, and have had no problems.

It is definitely a good idea to insulate your attic, but be sure that the ceiling joists are not hidden. Periodically you or the termite inspector will need to crawl around up there, and you’ll need to see the ceiling joists to know where to step. R19 should be OK if the joists are 2×6 or larger. An attic fan also helps by reducing the load on the air conditioner.

You should also consider upgrading your electrical service when the panel is rewired. By today’s standards, with a smaller house, you should have 100-120 amps minimum. But with the air conditioning, electric kitchen, and if you have an electric dryer or a spa, you might need 150 to 200 amps. Your local electric utility may be able to help determine what you need by conducting an on-site survey.
