2. Air Conditioning
Air Conditioning Installation
The most conventional type of whole–house cooling is central air conditioning. As you
undoubtedly know, central air conditioning delivers cooled air throughout your home via
ducts and vents. It’s great for cooling even large homes, and offers incredible
convenience, thanks to control innovations like digital thermostats and zoning systems.
A second, newer option is a ductless mini split system. These systems are also capable
of cooling your whole home, via an outdoor condenser unit and several individual room
units. The major advantage of these systems is that they do not use ducts, so they are
ideal for homes that do not have any existing ductwork, or where space is at a premium.
From a very broad perspective, central air is better for larger homes and ductless mini
splits are better suited for smaller ones, but it depends on the situation. Your needs –
and budget –– may be better suited by one or the other.
Air Conditioning Maintenance
To ensure your air conditioner keeps working as it should, you need to have regular
maintenance performed on the system. This requires a trained professional to clean and
check your coils, the compressor and all other components. They will turn on and
inspect the system in the spring before the cooling season starts and check for any
problems that might crop up during the hotter months of the year.
Air Conditioning Repair
Even the most well maintained systems will eventually start to wear down. If a problem
does occur, you want a trained expert you can rely on to make repairs as soon as
possible. Whether the system suddenly stops working, stops providing even cooling to
every room of your home or begins to make a lot of excess noise, call us to inspect and
repair the problems immediately, before it gets worse.
Air Conditioning Replacement
At a certain point, spending money to constantly repair your old air conditioner just
doesn’t make financial sense. If your air conditioner is in poor condition or is using a
tremendous amount of energy to get the job done, it may be time for a replacement. If
you find yourself in this situation, we can help you determine the best modern, energy
efficient model to choose as a replacement for your home.

4. Indoor Air Quality
Types of Air Pollutants
Some of the more common air pollutants found in homes include pet dander, pollen,
bacteria, molds, and cigarette smoke. These can cause anything from mild irritations to
allergic reactions that may require medical attention. Some of the more serious
pollutants commonly found in homes are combustion pollutants, which are gases or
particles that are created when fuel or other materials are burned. Carbon monoxide is
an odorless and potentially deadly gas that is a byproduct of burning fuels, such as gas
from a furnace. Nitrogen dioxide is another dangerous combustion pollutant commonly
found in homes that you should be aware of.
Improving Indoor Air Quality
But the humidity level in the home also plays a role, so you may want to consider a de–
humidifier or a humidifier depending on how much moisture is in the air inside your
home.
Proper ventilation is another important part of preventing pollutants from getting trapped
inside your home, so make sure all of your exhaust fans are working properly and free
of dirt or debris. Cleaning and changing the air filters will also keep pollutants from
circulating in the indoor air through your heating and cooling ventilation systems.
Toxic gasses can leak from a damaged or rusted furnace heat exchanger or from faulty
flues. It is important to note that there is no evidence that these gasses can be filtered
by air purification systems. Schedule regular maintenance visits with one of our
experienced HVAC technicians to check your heating and cooling system for gas leaks
or other safety issues.

5. Plumbing
Plumbing Installation
Your plumbing system is a complex series of pipes, drains and fixtures that need to be
properly installed to work as intended. A single misaligned washer can directly impact
your water pressure and the effectiveness of your fixtures. We offer expert installation
services for plumbing system components.
The key to effective installation of new fixtures and pipes is proper sizing, use of the
best quality materials, and an understanding of your family’s needs. If you have a
remodeling project or simply want to replace a single fixture and you want to ensure the
job is done right, call us today.
Plumbing Repair
There are a number of reasons your plumbing might stop working properly. In some
cases, a clogged drain can slow down every fixture in your home. A leaky pipe can
reduce water pressure and increase your water bill. A dripping faucet can be incredibly
annoying.
If you notice something not working quite right – whether it’s your water heater failing to
provide enough hot water or a wet patch on your lawn that you’re afraid might be the
result of a leaky pipe – you need to act fast. Most plumbing repairs are routine, requiring
a patch that takes very little time and costs you little money. However, when a small
problem is ignored it can become a major problem.
Plumbing Maintenance
One of the easiest ways to avoid the cost of emergency repairs is to have routine
annual maintenance performed on your plumbing system. Routine maintenance
involves checking for leaks in exposed pipes, checking for corrosion in or around the
pipes and joints, testing water pressure, cleaning sediment from faucets and shower
heads, checking the flush handle of your toilet, and making sure each drain empties as
quickly as it should.
Plumbing Replacement
As durable as modern plumbing parts have become, pipes and fixtures are only
designed to last so long. There are a number of signs indicating that you may need to
replace some or all of your plumbing system. Excess corrosion or leaks in your pipes is
always a sign that replacement may be necessary. Often, small parts of the system can
be replaced at a time to make it a more affordable project, but it’s important that you call
for inspection or routine maintenance sooner than later so the process can be started.

6. Water Heaters
Tank Hot Water Heaters
The simplest type of hot water heater is tank system. Tank based water heating
involves a single tank, operated with gas, oil, or electric heat. These tanks must be
carefully selected based on efficiency and the individual home’s hot water needs. The
newest tank models will last for many years and require only a minimal amount of
maintenance, some of which can even be done by homeowners themselves.
To select a good tank water heater, you must first measure the total hot water needs of
your home. This requires careful estimation of how much water you need in any one
hour. A professional can help make these measurements.
Tankless Hot Water Heaters
Tankless water heaters are relatively popular right now because they allow you to heat
only the water you need. They apply heat directly to the water supply, turning on only
when needed. When someone turns on a hot water tap somewhere, the system will turn
on and heat water for as long as the tap is active.
While a tankless hot water system costs more to install, it saves a lot of money on
monthly energy bills over the long run and doesn’t require combustible fuel to operate.
It’s a powerful solution for anyone that wants to reduce their carbon footprint and save
money by eliminating the need to pay for energy that keeps water hot inside a tank,
whether it’s being used or not.
Solar Hot Water Heaters
The third option on the market and one that is growing in popularity is solar hot water.
Solar water heaters require a solar heat collector on your roof. That heat collector
gathers energy from the sun and passes it to water or coolant in pipes on the roof. If you
choose a direct heating system, water is circulated to the roof to gather heat and then
carried to your fixtures for use. An indirect system uses coolant like antifreeze to carry
heat from the solar collector to a heat exchanger in a tank. In the heat exchanger, the
coolant passes the heat it gathered to your water supply.
The best thing about solar water heaters is that they can be used in conjunction with
solar air conditioners to provide cooling to your home in the summer. These systems
are slightly more expensive, but for places with high cooling costs, the added benefit of
solar power for both hot water and cooling can save you quite a bit of money over time.
